Dear all,
I have a pair of stereo images provided by a stereo sensor (the Zed camera). I do not have access to the camera (no camera parameter was provided). I am asked to measure the distance to a distinct object in the images using the stereo pair. I have never performed 3D reconstruction from stereo pairs, however I do not think we can infer actual distances to an object from a stereo pair without having the parameters of the cameras. I guess I can only provide a depth map.
My questions are : 1. Is it possible to have the distance to an object in the scene from a stereo pair without having the camera parameters ?
- If we have the camera parameters, what are the steps to follow in order to measure the distance to an object in the scene (or at least have a depth map with the correct distances in meters for instance)
Thank you for your help.
