Depth map from stereo pair using local method (matching windows) DMAG2

[@marianchirila2760]

Ugo, you have really good and comprehensive knowledge in 3D. Is it possible to obtain a 3d object(as mesh) from a image that is imitating the 3d effect with shades?

[@ugocapeto3d]

Thanks Marian. You should be able to use depthplayer.ugocapeto.com and save as an .obj the 3d scene (no colors though). I am trying to think if there are other ways. Surely, you should be able to use blender for such a purpose. Maybe somebody else can chime in about other ways to do it!

Oddly enough, sometimes that information is kind of naturally encoded in the mesh if the colors are monochrome. I've done a lot of testing, as Ugo here will attest to. I took a screengrab of Star Trek TNG, and used it as the depth map, no alterations, somehow, the back wall's depth information was mostly there, everything else was a pointcloud nightmare, but the back wall of the Enterprise D's bridge naturally worked as a depth map.

Thank you so much for your replies. The issue is, if applying the image as a depthmap we obtain a lithopane, which is not relief as is not based on shadows for 3d effect but on light filtering. Is there any trained A.I. to understand that a grey colour from the image is a shadow of a creast, not a hole?

@@marianchirila2760 AI depth maps aren't entirely accurate, but you can produce one in GIMP, by tracing out the image. Would you mind if I saw the image?

Hi, great video. Have you got something to do the displacement (right eye) from 2D + depth map ? Python script or something like this ?

[@ugocapeto3d]

There is software already to do this. I am thinking StereoPhoto Maker but there are others.
