Abstract

This paper presents a new 3D coordinate measurement method based on linear camera equipped with cylindrical lenses (LCEWCL). The LCEWCL has prominent advantages in high-precision coordinate measurement and dynamic position-tracking owning to the high resolution and outstanding frame rate of linear CCD. Every LCEWCL is a one-dimensional angle-measuring unit which can confirm a plane passing through the light spot. With three or more LCEWCLs arrangement in front of the measurement field, the 3D spatial coordinate of the light spot is reconstructed by multi-angle intersection. Experiments are conducted to validate the accuracy and effectiveness of the proposed method and good results have been obtained.
