Abstract

PURPOSE: To enable the outside shapes of objects having curved faces, etc. to be measured with high accuracy in the absence of contact by providing projectors and photo detectors which project and receive laser beams to the three-dimensionally movable measuring member.
CONSTITUTION: Bodies 1 and 1' of an automobile are radiated by the laser beams which are bisected by a half mirror 12, by which bright points A, A' are formed on the bodies. The laser beams corresponding to the bright points A, A' are then imaged on a light receiving array 16. The signals corresponding to said position information are supplied to signal processing circuits 18, 18', and the shapes of the bodies 1, 1' are continuously detected while the positions of the lenses 13, 14 and 13', 14' are in the intended set positions with respect to the target object or not is being observed
