Hello,
i have been trying to reconstruct a 3D surface out of 2 given stereo images. Basically i need to create some kind of surface plot with the texture of a given image at the correct real world coordinates, so i cannot simply use the "texturemap" feature of matlab.
To make it a little bit more clear i try to do something like this:

Where i have the two pictures (from left and righ camera) and i try to create the corresponding surface in 3D-world coordinates. - i need this to visualle check my computations
Can someone please point me in the right direction how to do this ?
thanks

Use these instructions as a starting point for what you are trying to accomplish:
The following shows the workflow for creating a 3D point cloud from two stereo images:
The instructions are for video frames, but the same functions apply for singular images as well.
To set the stereo parameters correctly, kindly go through the following:
You may have to rectify the stereo parameters, so here is the document with the necessary details:
I was able to find something for generating a 3-D surface from a points cloud on MATLAB central:
