Enhanced High-Precision and Non-Contact System for Measuring Geometrical Size of the Irregular Shape
Abstract: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. The article introduced the realization of the linear array CCD's driving circuit, and the hardware architecture of the array CCD online measurement system which take TMS320F2812 as signal processor. 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.
