Abstract

This paper introduces a precise way of using linear structured light sensor and CCD camera to measure the workpieces' shoulder characteristic size. The high precision measuring system and the core algorithms are mentioned in the paper to test the deformation of the light plane when the light meets the workpieces' shoulder surfaces. The measuring principle and the set-up of the system are described in detail. The core sub-pixel algorithms are proposed to locate the deformation of the structured light in order to improve the final precision. The experiments demonstrate the high repeatability and accuracy of the system. The experiments of accuracy estimation show the measuring precision could reach 0.05 mm.
