Abstract
A TV camera for visually inspecting an object is focused to a designated inspecting point, while being shifted to that inspecting point by utilizing a calculated distance from the TV camera to the next inspecting point without actually measuring the distance. The distance to the next inspecting point is calculated from a plane equation several of triangular planes formed over the object by a plurality of reference points previously designated on the object. The plane equations are calculated before executing inspection, by using distances, actually measured by distance measuring means, from the TV camera to the reference points.
