3d reconstruction from 2 images without info about the camera

September 14, 2023 by Tarik

StereoRectifyUncalibrated calculates simply planar perspective transformation not rectification transformation in object space. It is necessary to convert this planar transformation to object space transformation to extract Q matrice, and i think some of the camera calibration parameters are required for it( like camera intrinsics ). There may have some research topics ongoing with this subject. … Read more

3D reconstruction — How to create 3D model from 2D image?

May 30, 2023 by Tarik

As mentioned, the problem is very hard and is often also referred to as multi-view object reconstruction. It is usually approached by solving the stereo-view reconstruction problem for each pair of consecutive images. Performing stereo reconstruction requires that pairs of images are taken that have a good amount of visible overlap of physical points. You … Read more
