I am interested in getting the 3D location of a specific object (Using stereo vision) giving Its location and ROI in the left image, in addition to obtaining its location in the right image. All I found online is how to get the disparity map using (StereoBM::operator()/ cvFindStereoCorrespondenceBM). What is the approach ? how can i get the disparity of that object, is there a direct way of doing it after getting the disparity map or i should match the object first in the right image to get the disparity, can you suggest an good algorithm to match the object , I hope you can show how to do that with some code, at least getting the disparity of a specific object. thanks
