WitrynaNow, as usual, we load each image. Search for 7x6 grid. If found, we refine it with subcorner pixels. Then to calculate the rotation and translation, we use the function, cv2.solvePnPRansac().Once we those transformation matrices, we use them to project our axis points to the image plane. In simple words, we find the points on image plane … chute blockers for zero turn mowers
