WebBecause we know the light ray from captured object (x0,y0) comes through the pinhole (0,0), the change in horizontal direction is x0 - 0 and on vertical y0-0. The slope of the ray of captured object is therefore x0/y0. And because the point (x1,y1) on the image plane is the same light ray, therefore it lies on the same line as the captured ...
