Home-build 3d scanner


#1

Hi all.
I just wonna show you my friend’s and mine project we are working on.
The PR-SCAN lol
It’s 3d scanner based on linear laser, but because mine laser will arrive only in 10 days,
we use max to set-up scene and get simulated pictures.
You can find more on http://3d.raca.biz
Any comments are welcome

Pretty impressive! What will the new laser add to the system?? So far looks great for a home built system, keep on tweaking it.:thumbsup:


#3

Now if you could only build a 3d printer to compliment it… :smiley:


#4

I’m not gonna ask where you aquired a brain for scanning :twisted:


#5

is there more info on how we could do this, that looks GREAT


#6

Basicly all you need are this four thing:

  1. web cam or better yet digital camera
  2. linear laser to project the red line on your object
  3. rotating table with some kind of degree mark
    and finaly
  4. software, which will calculate all data from pictures and create a 3d point cloud

very good explanation is here: http://www.chromecow.com/MadScience/3DScanner/3DScan.htm

try googling for “diy 3d scanner” for more

Hi

We upgraded vertex optimization.
Little analyse on webpage.
Next on list are edges.

That’s really impressive! Those shots are quite a bit better than the last ones! Keep us updated with your progress! GJ!:slight_smile:

Quite a welcome alternative to the $20,000 commercial hardware. :slight_smile:
Curious though… What happens with your script if there’s a break in the model’s geometry?
Like say you had a can with a 1inch hole in the side. Have you coded it to take into account that break in the laser line?

:thumbsup: RC1 DEMO released :thumbsup:
Try it

restricted on 20 samples

Some of their earlier images featured a bottle of fabric softener( or something like it) which had a handle on it. The hole was shown just fine, although their more recent render of the fire hydrant looks quite a bit better.


#12

I’m not so sure that they would work the same way. With a handle, if you put all of your samples together (provided you’ve taken enough), you can still make out the geometry within the hole. In my can example, I’m just talking about a hole in one side of the can, so you’re not going to be getting -any- geometry within the hole. So I’m just curious to know if the software would interpret that properly to create a hole in the mesh as well.
If you look through some of the laser scans for the fire hydrant, you can clearly make out breaks in the geometry - where the laser line went flat against an extrusion. I’m guessing that their software is coded to ignore these breaks, and stitch the lines together at the closest points to these breaks in the lines. In the example I’m suggesting, I’m just wondering if it wouldn’t do the same thing there, since it will not be reading any actual geometry within the hole in any of the samples. Would those gaps in the laser be stitched, or not?
Not really a matter of the program’s functionality (honestly, how often is someone going to cut a hole in a can and try to scan it? :stuck_out_tongue: ), just curiosity.


#13

I just wanna add that this application requires Microsoft .NET 1.1 framework

I got my laser.

Hi, me again.
With a pumpkin scan


#16

Don’t Linear Laser use lights to reflect and judge all of what the laser reflects off of? If so will the laser only be useful in low light situations, so the lasers detemination isn’t altered by the light?


#17

Upgraded to FLAT scan and poly output

@NinjaSquirel: Wrong, laser do emit light, so the darker the better.
PS: all mine scans were done in extremly bad condition :thumbsup:

Very curious.

On your site you said you have a pc controlled rotating turntable. Do you have any pictures, how did you build it? Have you written the software to control it? Have you thought about how to control the cam from the pc too? Sorry about all the questions. I’m building a laser scanner for a class here at my university, and you seem to have alot of great ideas. Get back to me and lets see if we can get some more buzz started about this subject.

This is awesome.
Scan some more things. Looks great.
