DIY 3D Scanner

Fiend3d

The highest purpose of mathematics is that to find hidden order in the chaos that surrounds us
Norbert Wiener

Hello!
This material is about how to create a 3d Scanner with your own hands. I will try to explain the logic of his work on the fingers.

Inspired by this:
http://en.wikipedia.org/wiki/3d_scanner
I also wanted to make myself such a thing. More precisely, this is one option for solving this problem from an infinite number. This, of course, will not be an ultra-precise instrument, but I hope you will be interested. nine0003

What you need to start the scanner:

1. Web-camera.
2. Lamp.
3. Two square sheets perpendicular to each other.

Web-cameras are now very cheap: it cost me 600 rubles. (D-Link DSB C320). Of course, the better the camera, the better the results.

I'm proud to present you my device:

Shadow-casting cardboard (should be flat and cast a shadow in one plane). This will mimic the operation of a laser that shines in a plane, which you can also use if you have one (you can order it on the Internet, it costs about 20 USD). Naturally, the laser is better than the lamp. nine0003

Now about the principle of operation. Let's look at this picture:

We see a shadow falling. The shadow line should be clearly visible both on square planes and on the scanned object. Angle ABC is (as you should have guessed) a right angle.

Let's take a closer look at what we need from this:

Notice the line of intersection with the square planes and the scan line. All points on these lines lie in the same plane. If you look closely at the line of intersection with the planes, you will find that they form three points (A,B,C) of intersection with the planes. This means that we know three points from the plane in which the scan line (and the line of intersection) lies. Three points is all that is needed to construct the equation of the plane. nine0003

Knowing the coordinate of the camera, we can emit a beam from the camera to the scanning line. The intersection with the shadow plane will be the future 3d object.

It is very difficult to calculate the camera coordinate with points 0,1,2,3,4,5. However, we can manually calibrate the camera in the 3d editor.

I prefer Maya and will do in it and describe everything in MEL.

If you think about it, everything is very simple. I even believe that the human brain is guided by the same principles when judging the distance with one eye. If we count the picture without a shadow, then the objects will “hang in the air”, i.e. the eye cannot determine the location of the object. Its coordinate can only be calculated if the object is moving...but I'm tired. nine0003

And so. If you do not understand what the equation of a plane is, then I will try to tell you how I understand it.
Despite its invaluable power, the plane is described simply:
Ax + By + Cz + D = 0 (where A, B, C and D are constants, and A, B and C are not equal to zero at the same time)
This is the general equation of the plane. In other words, on the Internet you can find a lot of things about the plane.

References have very complex-sounding definitions. Personally, I think of a plane as a normal and the distance to the plane from the center of coordinates. The normal is a unit vector and the distance is a scalar. nine0008 Imagine a normal: it describes a plane passing through the center of coordinates, and then move this plane in the direction of the normal by a known distance. It turns out that the plane is four scalars or one vector and a scalar.

In MEL, a plane can be described as follows:
float $plane[4];

It's just four numbers. You can get them from three points (three points are three vectors). An example of a solution in MEL:

It looks cumbersome, because I try very hard to comment in detail, but if something is not clear to you, then these are simple operations on vectors. Consult any reference (or even the Maya manual). There is nothing super complicated here. nine0003

We already know how to find the plane. Now the camera position is vital. To calculate the beam from the camera to the scan line.

Camera calibration is a very complex mathematical problem. And I did not dare to torture myself and (God forbid) you with this occupation. I thought that the easiest way is to manually set up the camera and take the coordinate from it.

To do this, I created a scene in which I created a personal camera and a frame for fitting future points, which will also be assigned manually. nine0008 Yes ... it's not very fast, boring, but there are no restrictions on the material of the sanitized object and its environment. So there are plenty of pluses in this method (the best plus is, perhaps, the ease of implementation).

It is convenient to perform camera calibration when the picture is adjusted to the Resolution Gate.

The camera position has appeared. Now you need to learn how to calculate the intersection of a ray with a plane. To do this, you need to understand what a beam is. A ray is two vectors. One vector is the beam start coordinate (in our case it is the camera), the other one is its direction. A direction, like a normal, is a unit vector (a normalized vector). nine0003

You can explain in words how to calculate the intersection:

As you can see, the solution is very elegant:

Well, the math is over.
The scanning process itself looks like this:

The function ( createScannerPoint ) creates points (spheres) of the future object and places them in a special group (final_group), which is convenient to show and hide from view using additional buttons on the interface:

If you can call it an interface. And what else can you come up with. It seems to me that the code of complex interfaces is extremely inconvenient to read (even if you wrote it yourself), but this is still a lesson.

Resources:

1) Project Maya 8.5 (ma)
2) Script

Run Maya project and script (source "3dScanner.mel";).

We look at how everything works: we pull the locators. Now we shoot video from the webcam:

We adjust main_camera together with the connected Image Plane (with playback of the frame sequence from avi enabled). As I said, it’s convenient to customize according to Resolution Gate:

To increase the accuracy, first use alt and the mouse, and then Move Tool, Rotate Tool and tweak the viewing angle a little, if necessary. After fitting, make the camera Lock (in the additional window tools, this is done with one button).

I have my unfortunate digital camera that can shoot a maximum of 640 * 480 and it does it terribly. In principle, you can use a digital camera or camcorder connected to a computer. Since 640*480, then these numbers should be in the Image Size settings. nine0003

Now, without being nervous, manually move the sight (target) along the scanning line, remembering to move the locators that form the shadow plane (p1,p2,p3). It is also convenient to put the createScannerPoint command on the hotkey or use the G button after running the command from the Script Editor.

As a result, we get a set of points in three coordinates. The more accurate your movements and technique were, the less noise the final result looks like.

That's it.

In fact, I was very upset by the quality of my technique: a soapy and very small picture, there are catastrophically few frames per second and my monitor is too small for accurate work. The biggest bummer is the lamp. It gives a diffused shadow in any case. A special laser is needed (although it is cheap, but my experience with our mail discouraged the desire to order it). nine0003

You can make a NURBS curve from each scanned line and run a loft surface on them. Or write a script that builds a grid based on the received points, the coordinates of which you can take from the spheres.

The lesson is structured in such a way that it would be difficult to scan without understanding how it works. I don’t even know if this is good or bad, but I thought that the principle here is more interesting than the implementation and this was the focus of the lesson (or article?). In short, I myself do not know what I wrote. nine0003

I hope you enjoyed it and thank you for your attention.

I would like to add that the method is not tied to a program. You can implement this in any 3d graphics application that has a built-in interpreter.

2007-10-09

Maybe, of course, I'm not far from the intricacies of programming scanners, but I didn't smile at all that this is all done in Maya itself, the question follows - why do you need to scoff at the program like that? if there are already free programs with similar capabilities and even better, I can envy the current in one thing - this is that MEL to know this archive is important for Maya, and so I will put an average score. nine0003

2007-10-10

Yes, of course, all this is interesting, but in practice there is little use..... without a license) and a laser is required). And the one that is, has a lot of limitations, although it is inexpensive. The benefit appears if you use an HD camera and a laser. And I don't have them. The accuracy of my webcam is sorely lacking. In conjunction with the lamp especially. But even in such conditions, I can scan the teapot. This will take me a little time. If you increase the size of the sheets, get a very bright lamp (preferably a laser for 20 bucks), then you can scan a person's face. And in this case, there is no restriction on the material (the skin is translucent and can confuse the beam search algorithms). You can judge for yourself what quality my sources were. And their availability. In paid (I'm talking about the cheapest) devices (written in the instructions), you need to ENTER the camera coordinate. I find calibration in Maya a thousand times more convenient, accurate, and faster. I wanted it to be interesting. Still, I think everyone understands that it is unreasonable to expect great use from a table lamp, but it is fun to play with it :) The description of constructing a surface by points deserves a separate article. I suggested only doing Loft according to the scanned curves. This should work. nine0003

2007-10-10

If you are interested :) Then read this [url]http://www.vision.caltech.edu/bouguetj/index.html[/url] Solutions based on small scripts are very flexible and change to the necessary needs in half an hour. Pay attention to this example: [url]http://www.vision.caltech.edu/bouguetj/SunScan/images/car_anim.gif[/url] If you find the same platform with the car, and measure the height of the wall, then you can model this sketch in Maya (blender, xi, 3dmax ...) and calculate the equation of the plane from the shadow cast by the stick that he manually moves. After being calibrated into the chamber. [url]http://www.vision.caltech.edu/bouguetj/SunScan/images/car6s.gif[/url] [url]http://www.vision.caltech.edu/bouguetj/SunScan/images/car4s.jpg[/url] In my opinion, a lot of fun. The flexibility that 3D editors provide is hard to overestimate. nine0003

[quote] if there are already free programs with similar features [/ quote] dimson3d, this tutorial proves that Maua's possibilities are almost limitless. The lesson is interesting and original. 5\5 Of course, in practice this is rarely applicable, but still)) IN EXCEPTIONALLY GOOD SENSE :)))))))) 5/5

2007-10-10

I didn't understand anything. 5/5 :)

2007-10-10

I seem to have seen this lesson (similar) somewhere else I don’t know who the avtar was, but we cross our fingers that you are, and that you didn’t drag him away :) and finally the quality of the resulting models is not very good :)

2007-10-11

It's not good to accuse people of plagiarism. I provided links to the source code at the beginning of the article. I am sure that you saw not a tutorial, but paid programs.

2007-10-11

This is not exactly plagiarism... This type of scanner was announced here on render.ru. But for him there was a separate program and he used the construction level (laser) So the idea is not his, but well done that he transferred it to max .... Although there is little sense from this . . Programs easily export to * .3DS. Yes, and it’s not actual ... Draw a teapot for 10 skunds, and if you want more, for example, the head will turn out from this scanner so crap that it will be scary to look at. For now, I stick to the old-fashioned methods, if you need something, we can make it with shoulder straps

I have been writing this article for three weeks. Multiple implementations. I fucking hate the accusations. I did not compete with paid projects: I wrote an article about how to implement it myself and I think that I coped with this task.

[quote] I have been writing this article for three weeks. Multiple implementations. I fucking hate the accusations. I did not compete with paid projects: I wrote an article about how to implement it myself and I think that I coped with this task.[/quote] The start is good. I like it. And the topic is relevant. Still, if you improve the system, it can be very useful in the future. But I consider this lesson unfinished, because. only the scan result is present. And it would be worth continuing until the final modeling of the scanned object. So 5/4 from me. And the fact that the lesson was written for three weeks is a little more. I think those who made similar paid programs or scripts have been working on this topic for more than one month. And so the quality is better. And you don't have to compete with them. If you are satisfied with this principle of the scanner, then it is not necessary that others will like it. My advice to the author is to continue to develop the topic and improve the scanning technique. Ato is tired of the fact that everything good is invented in the West. You look in a couple of years the script will turn into a full-fledged software product. Which is what I want. nine0003

"Shadow casting card (should be flat and cast a shadow in one plane). This will simulate the operation of a laser that shines in a plane, which you can also use if you have one (you you can order it online, it costs about $20. Naturally, a laser is better than a lamp." In my childhood, having nothing to do, I shone through a laser pointer through everything that was translucent, and now I noticed an interesting feature for this case, that if a test tube from a school chemist is placed in front of the laser pointer. laboratory, then the laser beam is refracted into a plane, if you recall the movie "Alien" in which the spacecraft was scanned ... In general, I wanted to say that the above principle can be brought to mind, instead of a test tube, use some kind of prism or pipette, etc. place on a tripod and move with the ease of your hand and not spend $20 on a bourgeois device...

>There is no free software for this (they work for free but don't save anything (no license) your statement is not true http://www.david-laserscanner.com/ the program is free, saves in obj, gives very satisfactory results instead of the calibration proposed by the author of the article, the program uses a special template that greatly simplifies this procedure >And in this case there is no limit on the material scan glass object

2007-10-12

by the way, the mentioned program not only saves the geometry in obj, but also captures the texture, UV (all this in a free module)

2007-10-12

remember the movie "Alien" in which the spacecraft was scanned . .. this is very intersting! but in general, a laser level is suitable - they are cheap and available

2007-10-12

ps This program did not start for me. And I can scan a car :) Can this program scan a car with a fence? Before you criticize, please read the lesson, it's not about that at all. nine0003

2007-10-12

You can also use sunlight and a stick. In theory, if a laser pointer is placed on a fast motor, then a % line should appear in the frame (but I haven’t tried it) Lots of things you can think of. This is what I wanted to say.

2007-10-14

As an idea, interesting, though not new. I understand that a lot of work has been done, but you must admit that it's "raw" ... For the efforts 5/5

2007-10-15

Bought a Deja Vu CD. In additions, there was a mention of the LIDAR 3d scanner, which was used to create three-dimensional rooms. Here's what I've dug up so far: [url]http://www.fxguide.com/article114.html[/url] Pay attention to the line: [quote]A Lidar scan was completed of a real church interior located in Los Angeles to serve as a guide for the look of the CG church. Pixel Magic's 3D department modified the geometry of the Lidar scan in order to give the illusion of a 300ft height ceiling, and to add more detail where needed. Lighting of the virtual set was matched to a master clip of the real church interior.[/quote] And further: [url]http://en.wikipedia.org/wiki/LIDAR[/url]

>Dip in flour and scan %) will you wash it yourself? :) >And I can scan a car :) Can this program scan a car with a fence? I guess, yes at least a full-length human body has been scanned by someone >Before you criticize, please read the lesson, it's not about that at all who is criticizing? you just said that there are no free programs, that they do not save anything - and I corrected you and so - quite an interesting article

2007-10-16

I have a cool cat figurine. Thought it would be cool to scan it. But it's matte black. The camera sensitivity was not enough to see the illuminated part. Decided to dump it in flour.
