Combined with the binocular vision system, the characteristics of the measured object, and the characteristics of embedded system, some improvement or expansion is done on the mature Harris corner detection algorithm and traditional corner matching algorithm, thus to realize fast and real-time measurement of 3D object without any reduction of the system accuracy. Ultimately a quick solution to the non-contact measurement is provided in this paper. 【Key words】binocular vision; embedded system; Harris corner detection; corner matching 0 引言
