laser and a camera on a movable platform

laser and a camera on a movable platform

Postby billsmith » Fri Dec 16, 2011 9:23 pm

To scan a high-detail, I want to apply this scheme:
3D_fixed_camera+laser.jpg
3D_fixed_camera+laser.jpg (7.73 KiB) Viewed 2885 times

Is it possible?
What settings are needed?

Your planned set-up doesn't work with DAVID. The camera has to stand still during one scan and the laser can be moved linear (like at your vertical stage) or can be panned.

If you need a high resolution, do it like Mattia here:

But if you intend to scan a person, do it with the structured light technique.

This way I looked. Resolution is limited by the camera. If you scan a high detail, the camera will have to put away. And we lose the details.
In my version, the program should give the command to Mixing Capacity. As in the usual 2D scanner.

p.s. Developers who make this possible. It is very necessary, and you is not difficult.

You don't have to put the camera away, you can scan close to the object and stitch all the single scans together and then fuse them.

Your suggestion was already discussed:

And if it isn't difficult then you can give some hints to the DAVID programmers how to do it.

Hi,

old wish and I agree, should be not so difficult .... but needs an predictable motion of the Laser/Cam combo (or object)
see also here:
viewtopic.php?f=3&t=861

Also look at the customize hardware options in DAVID. You might discover that such stuff might come in future versions.

Predictable movement to do just. For this I use the cnc machine.
It remains to wait for this feature in the new version. :?
