Research on High Precision and Non-Contact Measuring System for Geometric Parameter of the Irregular Shape

Abstract:

Traditional measurement for geometric parameter of the irregular shape is considered as high cost and low efficiency, and large-scale automatic measurement cannot be achieved. In this paper, a low-cost, high-precision measurement system of irregular shape is presented. The system based on linear array CCD non-contact measurement method, in which a CCD camera is controlled to scan the projection of thread in the parallel optical field to acquire thread images. Meanwhile, an edge detection method based on gradient operator and linear fitting principle is proposed, the results show that the design improve the measurement precision efficiently.
