ATLAS 3D: Getting Started with ATLAS 3D

ATLAS 3D: Getting Started with ATLAS 3D - Murobo.com

The following content instructs the user on how to assembly, calibrate, and scan with ATLAS 3D.

  1. Software Install (BYOP ONLY)
  2. Scanner Assembly
  3. Determining the Scanner IP Address
  4. Connecting to the Scanner
  5. Register the Scanner
  6. Hardware Calibration
  7. Getting Good Scans
  8. Support Forum

Note: This step is for BYOP Kit backers only. All other kits have the software pre-installed on the SD card.
An ATLAS 3D software image is provided to make it easier for BYOP Kit backers to get up and running. It is located at https://s3.amazonaws.com/atlas3d/2015-05-01-atlas3d.zip. An 8GB or larger SD card is required. Instructions for writing the image to an SD card can be found at https://www.raspberrypi.org/documentation/installation/installing-images/.

In order to connect remotely to the scanner, the IP address of the scanner must be determined. This is most easily done by attaching a monitor, keyboard, and mouse to the HDMI and USB ports. Once prompted for login information enter the following:

  • pi for the username
  • raspberry for the password

If you are doing a wired connection to the scanner, insert the Ethernet cable and type the following command at the prompt.

  • ifconfig

The IP address of the scanner should be listed after the inet addr: for eth0. For example: 192.168.0.201. If you are connecting over Wifi, plug in the Wifi adapter and follow the instructions at Raspberry Pi Wifi Configuration. Type the following command at the prompt.

  • ifconfig

The IP address of the scanner should be listed after the inet addr: for wlan0.

NOTE: Depending upon how your home network is setup, you may be able to simply enter http://atlas3d/ (no .com) instead of the IP address.

Once the IP address is known, enter it into a web browser on the same network. For example, if the IP address is 192.168.0.6 you would enter http://192.168.0.6/ in the location bar of the web browser. You may be able to simply enter http://atlas3d/. The main interface for the scanner should come up at this point.

Register your ATLAS 3D scanner with the included 8 character serial number at https://www.murobo.com/register.php. The serial number is located on the bottom of the stepper motor. Then, enter the serial number on the Setup page by navigating to SETTINGS and then clicking Setup. This will allow the scanner to receive software updates.

This video below shows how to calibrate an ATLAS 3D scanner.

Before scanning for the first time, the hardware must be calibrated. Calibration is the process of moving the lasers and camera to the orientations that the software expects. The Calibration Item Model must be printed and used for the process. Calibration is performed from the Camera page.

The first step in calibration is aligning the the camera.

  1. On the SETTINGS page, choose the Calibration preset which has a camera resolution of 640x480 to have faster video feedback.
  2. Click the CAMERA link at the top of the page to begin calibration.
  3. Place the calibration item on the table.
  4. Move and rotate the camera until the red horizontal line is level with all 3 peaks of the calibration item. The horizontal line should stay at the peak of the calibration item towers whether the item is in the back or front of the table. If the line moves up or down when the calibration item is moved around the table then the camera needs to be adjusted vertically.
  5. Rotate the camera side to side until the vertical red line is at the center point of the turntable. This point can be more easily seen by placing a pin the the center hole.

  6. The horizontal red line should stay at the peak of the towers when the item is in the front as well.

The next step is to calibrate the lasers.

  1. Place the calibration item on the table to where the longest side is facing the camera and the front of the wall is at the center of the hole in the table.
  2. Turn on the right laser.
  3. Rotate the right laser until it sits over the vertical red calibration line.
  4. Turn off the right laser.
  5. Turn on the left laser.
  6. Rotate the left laser until it sits over the vertical red calibration line.
  7. Turn on both lasers and recheck alignment laser.

Once calibration is complete, the next most important part of getting good scans is balancing the lighting with the laser threshold setting. If the light is too bright then it will over saturate the laser line and make it difficult for the camera to pick it up. If the light is too dim the camera image will be noisier, the laser will appear to reflect off the object more, and the resulting scan will be much darker than the object. Before scanning an object, first select the Preset that you would like. Navigate to the CAMERA page and click the test button. Suppose we are scanning the object below...


Click the Test button to see if the current settings and lighting is appropriate for the object. The image below shows the resulting test image. The test image shows the detected laser line after processing the image from the camera. The gray pixels are those that are above the threshold value, while those below the threshold are yellow. The red line shows where the center of the laser was detected. To obtain a good scan, there must be a red line everywhere that the laser contacts the object. For this to occur, the threshold settings must be set appropriately. If the threshold value is too high (or there is too much direct light) then there will be gaps in the object. If the threshold value is too low then laser detection false positives can occur in the background pixels resulting in scans with lots of points floating around off the object. In the image below notice the gaps toward the bottom of the image.


We can correct for this by lowering the laser threshold value. The laser threshold value is close to the top of the SETTINGS page. Lower the value by half, save the preset, and generate another test image.


With the new laser threshold setting there is now a much better line at the bottom of the image. The object is not ready to be scanned. From the SCAN page click Start Scan to scan the object.


Once the scan is complete, click on the file link (STL, PLY, etc) to download it from the scanner.

Inexpensive but capable $200 Atlas 3D scanner

Business

Apart from the technological nuances of the printing process, the main difficulty in introducing 3D printing to the masses is the need to prepare suitable digital models. Not all people who are ready to buy a consumer 3D printer have the 3D modeling skills necessary to provide a full production cycle. Of course, in such cases, special portals come to the rescue, offering access to a great variety of three-dimensional digital models, many of which are offered free of charge. However, the use of other people's designs, by definition, limits the individual creative possibilities of users - the flight of someone else's imagination will never become your own, and therefore the lack of the ability to create your own designs makes 3D printing much less attractive.

nine0003

This problem can only be fixed with simpler and more convenient applications, which is done using Draw in 3D, Morphi and other programs. But there is another point: 3D printing is attractive because of the possibility of copying. This feature alone can make homemade additive manufacturing more attractive. Hanger broken? Did the neighbor have a chic vase? Cracked violet pot? To recreate interesting objects, it is not at all necessary to have 3D modeling skills. A 3D scanner is enough - the main thing is that an object is available from which you can “copy” a design. nine0003

Unfortunately, most 3D scanners cost as much as decent 3D printers, which doesn't help their price appeal. An American engineer named Uriah Ligget offers his own solution to the problem: a kit for self-assembly of an inexpensive, but very capable Atlas 3D scanner. Why pay a couple of thousand dollars when you can assemble a good analogue with your own hands for $200? Why such a low price? Liggett chose to use the most inexpensive hardware and software components, the Raspberry Pi, in combination with open source hardware and software. The body of the device can be printed on a home 3D printer. nine0003

Liggett explained his motivation: “Like many other 3D printers, I purchased a 3D printer for the purpose of printing everyday objects for my own home. Sites like Thingiverse offer a great selection of models, but even they are not enough for my purposes. I came to the conclusion that for my interests, a 3D scanner was needed, with which I could create models based on existing physical objects.

Not wanting to spend a lot of money on buying his own scanner, Ligget experimented with the Autodesk 123D, but the idea of ​​a "cloud" solution did not appeal to him, especially since the quality, according to him, was unsatisfactory. And scanners of the right quality came with a hefty price tag, being for the most part intended for the commercial rather than the domestic sector. It was then that Ligget decided to create his own, inexpensive scanner. nine0003

Ligget opted for a turntable design to achieve a precise grip without too much fuss. The device uses a laser system to quickly generate high-resolution models. Measurements made by lasers are combined into a single polygonal grid to obtain a full-fledged 3D model. In fact, this is an analogue of the famous MakerBot Digitizer, which costs about $800.

The finished model can be processed using any standard software such as MeshLab before being printed. “The Raspberry Pi was an obvious choice as it supports 5 megapixel cameras, lasers and motors, and has enough memory and performance to process 3D scans,” explains Liggett. The Raspberry Pi does not require additional drivers or other software to be installed and can connect to the scanner via a web browser or Wi-Fi. The scanner itself uses the FreeLSS open source software available on GitHub under the GNU General Public License. nine0003

After placing an order for the device, the user will receive a set of .STL files for printing the device case from ABS or PLA plastic. All other parts will be supplied as a kit. At the moment, Ligget is considering two configurations. The first, "complete set", will include a Raspberry Pi B+, a 5MP CMOS sensor, a Wi-Fi adapter, two laser modules, an electronic board, a power supply, a stepper motor, rubber lining and feet, mounts, cables and files. for case printing. The second, reduced package will be designed for those who already have a Raspberry Pi. Whichever kit you choose, assembly is easy: no soldering is required, you just need to fasten the components with screws and ties. nine0003

Like many innovators these days, Liggett decided to go public funding by putting his designs and proposals on Kickstarter. The required amount was collected in a matter of days, and therefore the project can be considered a serious undertaking. Those who wish still have the opportunity to pre-order for $209. Deliveries of the first finished Atlas 3D scanners should start towards the middle of 2015, although the exact date has not yet been determined, and the design will be released to the general market by the end of the year. Those wishing to invest in the project can find additional information here. nine0003

3D scanners - pre-purchase instructions

In industrial and commercial applications - for the study of building structures and making accurate spatial measurements, for digitally capturing crime scenes and cataloging works art or fossils - 3D scanning has been used for many years. Meanwhile, 3D printing was gaining more and more popularity, especially among craftsmen and enthusiasts, and people wanted to read real objects and convert them into printable 3D models. nine0003

The market has of course responded, and today there are more low and very low price 3D scanners on offer than ever before. Prices for 3D scanners range from a few hundred to several thousand dollars, which should suit just about any budget. The decision on which 3D scanner to purchase depends entirely on what exactly it will be used for and how detailed you are going to scan objects.

Software Solutions

Depending on what you want to scan, you may not need to purchase a 3D scanner. It's possible that you already have the one tool you need to create 3D models, and this tool is in your pocket. There are several programs that take ordinary pictures, even taken on a smartphone, and then extrapolate the available data, creating a completely three-dimensional image. nine0003

This process is called 3D photogrammetry and starts by taking multiple pictures of the same object from different angles. The more images involved, the sharper and more detailed the final 3D model will be. This process may work on just three images, but for very detailed objects, dozens of them may be needed. Not only is this a less expensive option, it's also the best option for scanning 3D objects in public places or in the field where you don't want to carry additional 3D scanning equipment. nine123D Catch1 work on a smartphone or tablet. This makes it ideal for digitally capturing objects in public spaces that cannot be scanned in a studio—museum pieces, large structures, and natural formations. nine0003
