The Structured Light Image'S Outline Extraction

This paper presents a kind of method for the obtianment of curve surface information - the Structured Light Image Methed(SLIM). The key to the method is the outline extraction or the Structured Light Image(SLI). From the Image taken by CCD camera, to obtain surface geometric information is a new field for electric-lighted nontouching measuring. It is a comprehensive field,developed recently, consists of optics, machine. electronics, computer and image processing. In this paper, from Image grey level and perspective projection, the outline of surface can he got.
