Apparatus for measuring three-dimensional curved surface shapes.

摘要

A three-dimensional curved surface shape measuring apparatus of the slit light rotating type. In accordance with a composite image theta (x min , y min ) produced when a slit light is rotationally scanned with resect to a picture of an object to be measured and horizontal displacements xo and vertical displacements zo 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 distortions due to a perspective effect of a television camera.
