How can it be that i got negative values? The epipolar lines look really good. Thank you. |

Therefore i want to have a look at the implementation. Can Anybody tell me in which file i can find the implementation. Thank you |
2013-04-26 04:44:31 -0600 | asked a question | initUndistortRectifyMap - crop Hello, i have a question regarding the rectification and the reprojectImageTo3D method: in the function initUndistortRectifyMap the image gets undistorted, rectified and cropped... if i calculate the disparity map afterwards the disparity depends on the crop process, is that correct? Does anybody know by what criteria the algorithm cuts the image? Because by computing the 3D data (reprojectImageTo3D) i will get coordinates according to the crop process. It would be nice, if anybody can help me. |
