Traditionally, the surface contour test instrument or three-coordinate measuring machine is used in 3-D curved surface measuring system. Now a laser triangle measuring device instead of test probe is installed on the three-coordinate measuring machine, but this method is still limited by the three-coordinate measuring machine itself. On the basis of a thoroughgoing study of the principle of laser triangle measuring method, a laser two-triangle measuring system for 3-D curved surface is described.
