homogenious image transformation

Published by Martijn at 10:03 under PhD lab book

The homogenious transformation matrix for projection of one camera view onto another one, can easily be found using Matlab. This link explains how to open the Control Point Selection tool (cpselect(input_image, base_image, input_points, base_points);), compute the transformation matrix (t = cp2tform(input_points, base_points, ‘perspective’);) and finally transform the image. Computing the transformation matrix needs only to be done one time for a single camera set-up, so it could be pre-processed and the matrix can be saved for later usage.
