Abstract
This article is to introduce a newly developed method to measure three-dimensional displacement by only a single camera. To measure the 3-D displacement of the two objects A and B, two lighting diodes are fixed on object A. A convex and a translucent screen are fixed on object B, a CCD camera is joined together with the screen. The lighting diodes project two faculae on the screen throgh the lens. The position of the faculae can be detected by the CCD camera. The 3-D displacement of A and B can be calculated according to the position of faculae.
