WebFor example, distortion coefficients can be estimated for each head of stereo camera separately by using cv.calibrateCamera. Then, the images can be corrected using cv.undistort, or just the point coordinates can be corrected with cv.undistortPoints. References [Hartley99]: Richard I Hartley. "Theory and practice of projective rectification". WebDetailed Description. The functions in this section perform various geometrical transformations of 2D images. They do not change the image content but deform the pixel grid and map this deformed grid to the destination image. In fact, to avoid sampling artifacts, the mapping is done in the reverse order, from destination to the source. how many p-40 were built how many oz to make a cup
