Abstract
A three-dimensional curved surface shape measuring apparatus of the slit light rotating type. In accordance with a composite image .theta.(x', y') produced when a slit light is rotationally scanned with respect to a picture of an object to be measured and horizontal displacements x.sub.o and vertical displacement z.sub.o of an axis of rotation of the slit light with respect to an origin of a reference plane, a necessary computational processing is performed to determine a three-dimensional shape f(x, y) of the object surface which is free of distortion due to a perspective effect of a television camera.
