Laser scanner 3d modeling
What is 3D Scanning? | Laser Design
First of all, let’s be clear that 3D laser scanning is not magical. True, the technologies that make it possible are very advanced and quite amazing. But behind the mirrors—found in the laser probe (without any smoke)—there is a lot of know-how and experience that makes the laser scanning experience seem so easy to Laser Design customers.

What is 3D Scanning?
3D Laser Scanning is a non-contact, non-destructive technology that digitally captures the shape of physical objects using a line of laser light. 3D laser scanners create “point clouds” of data from the surface of an object. In other words, 3D laser scanning is a way to capture a physical object’s exact size and shape into the computer world as a digital 3-dimensional representation.
3D laser scanners measure fine details and capture free-form shapes to quickly generate highly accurate point clouds. 3D laser scanning is ideally suited to the measurement and inspection of contoured surfaces and complex geometries which require massive amounts of data for their accurate description and where doing this is impractical with the use of traditional measurement methods or a touch probe.
The 3D Scanning Process:
Data Acquisition via 3D Laser Scanning
3D Laser Scanning Process An object that is to be laser scanned is placed on the bed of the digitizer. Specialized software drives the laser probe above the surface of the object. The laser probe projects a line of laser light onto the surface while 2 sensor cameras continuously record the changing distance and shape of the laser line in three dimensions (XYZ) as it sweeps along the object.
Resulting Data
The shape of the object appears as millions of points called a “point cloud” on the computer monitor as the laser moves around capturing the entire surface shape of the object. The process is very fast, gathering up to 750,000 points per second and very precise (to ±. 0005″).
Modeling Choice Depends on Application
After the huge point cloud data files are created, they are registered and merged into one three-dimensional representation of the object and post-processed with various software packages suitable for a specific application.
Point Cloud Data for Inspection
If the data is to be used for inspection, the scanned object can be compared to the designer’s CAD nominal data. The result of this comparison process is delivered in the form of a “color map deviation report,” in PDF format, which pictorially describes the differences between the scan data and the CAD data.
CAD Model for Reverse Engineering
Laser scanning is the fastest, most accurate, and automated way to acquire 3D digital data for reverse engineering. Again, using specialized software, the point cloud data is used to create a 3D CAD model of the part’s geometry. The CAD model enables the precise reproduction of the scanned object, or the object can be modified in the CAD model to correct imperfections. Laser Design can provide a surface model or the more complex solid model, whichever results are needed for the application.

In modern surveying, the general meaning of laser scanning is the controlled deflection of laser beams, visible or invisible.
Within the field of 3D object scanning, laser scanning (also known as lidar) combines controlled steering of laser beams with a laser rangefinder. By taking a distance measurement at every direction the scanner rapidly captures the surface shape of objects, buildings and landscapes. Construction of a full 3D model involves combining multiple surface models obtained from different viewing angles, or the admixing of other known constraints.
The need to capture existing real-world conditions in a digital format has become increasingly vital across all industries.

US construction company Gilbane invested $60,000 in a FARO Focus-S 350 laser scanner, software, and employee training. At first glance, the amount seems too large for a small-scale firm. But, after the calculations, the company's management came to the conclusion that the investment will pay off in the shortest possible time. nine0003
According to Gilbane's director of 3D design, John Tocci Jr., after introducing the expensive new technology, the company began to use the equipment even in areas where it was not originally planned. The specialists managed to save $30,000 for one hour of Focus-S 350 and Autodesk Revit software.

At the time of the start of work, the architects had drawings made 85 years ago, and a little more than 4.5 thousand square meters of the old building. Using a 3D laser scanner, Gilbane digitized the training areas in one day. Modernization of load-bearing structures, as well as the main utility systems: plumbing, electrical and ventilation, was based on data obtained from scanning. nine0003
Quality Inspection with ScanTech
Source: 3d-scantech.com
The advantage of metal stamping over forging and casting is the lower weight and thickness of the resulting parts. The use of molds gives high accuracy and maximum compliance of the obtained parts with the specified characteristics, but does not completely exclude deviations and deformations. Which, in turn, can lead to difficulties in assembling finished products and reducing product quality. Therefore, constant quality inspection is a necessary part of production. nine0003
Having understood the problems of the manufacturer, ScanTech experts proposed to check the quality of stamped parts using the PRINCE laser scanner. The ability to switch blue and red laser modes allowed the device to combine the functionality of traditional portable and metrological 3D scanners. The mode of operation with an active beam of a red laser provides fast digitization of objects. In the case of increased requirements for accuracy and detail, turn on the blue laser beam mode. nine0003

Laser scanning and 3D modeling to restore the information model of the Rostov NPP
Laser scanning and 3D modeling to restore the information model of the Rostov NPP Authors: M. Anikushkin, E. Beletsky, E. Okunkova, S. Serkov, S. Smirnov.
2013
Despite the fact that the first terrestrial scanners appeared in the last century, there is no reason to claim that laser 3d scan is widely used in the design and construction of industrial facilities. The main reasons should probably be the still high cost of such systems and the lack of information on how to use them effectively in certain applications. However, interest in this technology and its demand in the surveying equipment market is growing exponentially every year, and the high cost of acquisition is increasingly offset by the offer from scanning service providers. Depending on the goals and objectives of the project, laser scanning technology can be effectively combined in a project with 3D design technologies. nine0008
Recently, designers of technologically complex industrial facilities are increasingly resorting to the use of intelligent 3D design. Due to the high detail of , 3D model contains a fairly large amount of information about the shape and parameters of process equipment, as well as all the necessary engineering and technical information for the formation and release of design and estimate documentation and subsequent purchase, supply, construction and operation needs. As a result, designers who are customers of measurement work now want to receive as a survey result not executive geodetic schemes with plotted design values and actual dimensions of individual structural elements, but detailed data in a three-dimensional representation containing an amount of information comparable in detail to the design digital model . Software plays an extremely important role in fast and efficient processing point clouds obtained from high-resolution laser surveys.
In modern realities, in the vast majority of cases, the Customer - the operating organization that orders the entire range of works, from a feasibility study to commissioning and commissioning - is faced with a situation where the design three-dimensional model of the operating object has significant differences from what actually built on site. Currently, there are proven solutions that allow you to quickly and efficiently obtain the so-called executive model of a plant or other complex engineering facility. The second task that design organizations face more often is reconstruction and deep modernization of existing engineering structures and enterprises of continuous operation. Existing technologies make it possible to automate typical tasks and increase the speed and quality of performing diverse work on restoring "from paper", that is, according to the documentation available in the archives, or in the absence of such, an integrated information executive model of an enterprise or its individual parts, depending on assigned tasks. nine0003
Let us turn to the description of the processes of restoring the information model. The software developer for lifecycle management of industrial facilities Intergraph recommends using the Smart3D 3D design module in conjunction with software developments from Leica Geosystems, which allows you to get a tool for restoring an intelligent 3D model from a point cloud.
Solution Leica CloudWorx acts as a software module for Smart3D, embedded in the powerful Intergraph Smart3D shell. This module is designed to work with a point cloud, that is, gaining access to the database where the point cloud is stored, and further processing the point cloud, as well as working with it inside the Smart3D software as a "substrate" for the purpose of accurate and error-free positioning of objects, measurements and design. In this program, based on the well-established technology Leica Cyclone , the entire toolkit of the Intergraph Smart3D system is used to perform measurements, correct data, visualize elements of scanned pipeline structures, build models based on the Smart3D object catalog and generate reports.
Simplified laser scanning technology is as follows. First, a work plan is developed, a laser scanning procedure is carried out with panoramic photography of the object. The rest of the work is carried out remotely from the facility. The scan results are pre-processed and as a result we have a point cloud - a virtual copy of a real object with millimeter detail. Geometric modeling is often carried out, the essence of which is to create a vector model from a cloud of points. The result of the stage is a geometric solid model of the object, available for import into almost any CAD system. nine0008 As a rule, a geometric model is used for the reconstruction of industrial enterprises - it is important for a designer to know where and how the existing equipment and communications are located, what are the geometric parameters of the room. The use of a three-dimensional model based on scanning data at the stage of reconstruction design can significantly reduce the likelihood of collisions and errors at the stage of construction and installation works. Within the framework of the project described below, another task was solved - a comparison of two models, design (as-designed) and executive (as-built). Such a comparison, carried out periodically during the construction of an industrial facility, makes it possible to control the quality of construction and installation works, improve the efficiency of construction process management, which ultimately significantly reduces the likelihood of violations of the construction schedule and going beyond the estimated cost. nine0003
Another significant challenge is engineering data management. The urgency of this problem increases with the increase in the complexity of objects, the detailing of models, the growth in the number and methods of presenting engineering information. To work effectively, it is necessary to use some tool that can “combine” all the data into an information model (“ as-built ”), which will later be used to manage a complex engineering object or project. Unfortunately, the possibilities of information modeling are often underestimated by operating organizations. Given the limited resources of engineering, administrative and IT personnel at the facilities put into operation, solving the problems of collecting information and tracking changes in order to form an updated information model seems to be an extremely difficult task, especially given the constant updates, re-equipment, overhauls and operational changes in the enterprise configuration. nine0003
New capital construction projects also face the challenge of handling large volumes of unstructured information that is regularly received from suppliers, equipment manufacturers and design offices. If this information is not properly processed directly in the process of its transfer from the contractor to the customer, then it may be distorted or lost forever.
Speaking of a “data collection” tool, it is essential to find one that allows you to organize data in order to enable you to make optimal management decisions. It is this approach that allows navigation with a high degree of accuracy, while displaying real connections between design positions, as a result forming an intelligent model of the operating object. nine0003
The implementation of the laser scanning technology described above, the creation of a point cloud and a geometric and subsequently information model, allows you to fully familiarize yourself with the features of solving the problem of restoring the information model of an existing object.
You should refer to an example project illustrating the application of the technology described above. In 2013, a team of specialists, which included representatives of companies Intergraph (Intergraph PP&M Russia), Trimetari (St. Petersburg), Navgeocom (Moscow), implemented a project to obtain a three-dimensional information model of an engineering facility (reserve diesel power plant of the 3rd power unit of the Rostov NPP) based on laser scanning technologies. The Customer was the leading design institute in the structure of the State Corporation Rosatom - United Company OJSC NIAEP - CJSC Atomstroyexport. The main goal of the work is to test the effectiveness of laser scanning and Intergraph technologies as a method of building an "as built" model when reconstructing existing objects, when designing new objects based on existing ones in order to replicate the design solution, at the operational stage, etc. It should be noted that the authors cases of similar projects being carried out in Russia are unknown, although foreign design and operating organizations have long and successfully used the capabilities of laser scanning and Intergraph CAD to perform these tasks. nine0003
The object was Rostov NPP - one of the largest energy enterprises in the south of Russia. Power unit No. 1 is at the stage of pilot operation at a capacity level of 104% of the design one, power unit No. 2 was put into operation in 2010. Power units No. 3 and No. 4 are currently under construction, the launch of which was scheduled for 2014 and 2017. Electricity generation is over 25 million kWh per day and about 8 billion kWh per year. nine0003
Laser scanning work was carried out at the reserve diesel power plant of power unit No. 3. This facility has 3 levels located at elevations from −7 m to +9.6 m.
When planning work, the following list of stages was approved:
To perform field work on laser scanning, the scanner ScanStation P20 was used - the latest model of the Swiss manufacturer of geodetic equipment Leica Geosystems . The device has excellent technical characteristics for shooting complex industrial structures - a maximum range of 120 m at 18% reflectivity, a distance accuracy of less than 1 mm, a speed of up to 1 million points per second, a built-in camera. In addition, the possibility of continuing the project with the shooting of the object from the outside in the cold season caused special requirements for the “endurance” of the scanning system. The parameters of the P20 scanner - operating temperature from -20°С to +50°С and dust and moisture protection IP54 - allow the device to be used in harsh climatic conditions. nine0003
Initially, a work plan for scanning of was developed at the facility, a registration method was chosen, and scanner installation locations were determined. Direct laser scanning was carried out in 360-degree mode with panoramic photography of the object. Over two days of field work, surveys were made from 38 stations. Scanning was complicated by the ongoing construction and installation work at the facility. Advantages of the method - non-contact and speed surveys - allow you to minimize the impact of laser scanning work on construction or operational processes at industrial facilities.
All subsequent work was carried out in camera, remotely from the object. The initial processing of laser scanning data - registration of scans (combining into a single coordinate system) was completed in one day. The registration result - point cloud - is a virtual copy of a real object with millimeter detail (see Figure 8). The total number of points in the final cloud was 1.3 billion. nine0003
Geometric modeling of was performed in the Leica Cyclone software. It took 23 man-days to create a vector model from a point cloud. Despite the fact that the Leica Cyclone has ample opportunities for automatically fitting graphic primitives into a point cloud, modeling work is mostly manual and very painstaking work.
To download point clouds and their subsequent processing in Smart3D, the following software was used:
The file was loaded into the same working project on which the object was built, which made it possible to combine the design model and the actual data (as built). Next, the object was divided into sections according to the alignment construction axes, after which we analyzed these sections for compliance - with the identification and recording of discrepancies. Thus, as a result of the work done, we received a list of actual discrepancies, supported by visual materials. This made it possible to quickly eliminate the discrepancies found even at the construction stage and significantly improve the quality of the final object, ultimately achieving its full compliance with the working documentation. nine0003
It is difficult to underestimate the opportunities that open up:
With the help of Cyclone or CloudWorx you can organize bulk data processing. nine0272 Cyclone works as a client-server application, so you can create simultaneous access from multiple computers to one database. At the same time, all changes made on one computer will be immediately visible on others. This property significantly speeds up the processing of large data arrays.
Remote and mobile access to ensure a complete work is carried out using the SPF Web portal or the Dashboard. nine0008
The obtained three-dimensional model of the object and high-resolution panoramic images obtained as a result of laser scanning were published in the SmartPlant Foundation, a portal integration core of integrated design, an information flow management solution from Intergraph.
In addition, as part of the work on the pilot project, JSC NIAEP specialists transferred about 600 MB of unstructured documentation for 7 sections of the project in various formats. Most of the submitted documentation was in scanned form. With the help of the ABBYY software product, the scanned documentation was processed, and the xml files with smart data and source documents were loaded into SmartPlant Fusion. Documentation in dwg, doc, xls, etc. format was processed using the built-in SmartPlant Fusion tools, and no preliminary recognition was required using ABBYY. In SmartPlant Fusion, the downloaded documentation was automatically, according to pre-configured rules, structured by project sections. The classification of project items according to the relevant standard was also set up. nine0003
SmartPlant Fusion "can" process various sources of information, extract data in accordance with the configured rules, and, based on this data, restore a consolidated information model. The project used various approaches to obtain data. Information can be obtained from the stamp of the document itself (for example, the document type and description from the document stamp), from the file name (for example, in this project it was the archive number of the document), from the folder structure of the transferred documentation set (in the project, based on the folder structure were classified documents). The system allows you to extract information on equipment and related documentation, build relationships and navigate between these objects. For example, by selecting the desired design position (pump, valve, etc.), you can view all documents in the system related to it, for example, a process flow diagram, wiring diagram, specifications, etc. The navigation mechanism allows you to switch from a design position to a photorealistic panoramic image obtained as a result of laser scanning and loaded into the system, and see how this equipment is mounted on the site. This functionality will help to compare the actual state of the object with the way it is displayed in the engineering documentation.
