In order to implement two-dimensional moving object's non-contact and real-time speed measurement  in this paper  wc proposed a new method which was based on the characteristic of FPGA and a real-time two-dimensional correlation speed measurement was proposed on image processing using high speed CMOS shown in figure 1. Experimental installation was shown in figure 2  a cardboard with images which was fixed in electric control movement device was moving to simulate moving object  the CMOS image sensor gathered image signals of the cardboard and the image signals was output to FPGA after a serials pretreatment such as binaryzation etc. Logical operation insteaded mathematical operation on FPGA to implement two frames image's cross-correlation operations as the formula (10) in this paper  and finally calculate the two-dimensional velocity. Through experiment result of table 1 we drawn an conclusion the accurarcy of the method in this paper was less than 1 pixel and the method can be used at a certain speed ranges of two-dimensional  real-time speed measurement. 2010 IEEE.

Based on laser optical triangulation displacement and grating displacement inspecting principle  optoelectronic non-contact inspecting method and inspecting system for the taper of small-calibre bore are presented. In this paper  the constitute and overall structure of the system are described. Then  the taper inspecting method and principle of the bore are discussed and theoretically analyzed  and also  the corresponding mathematics model is established. As inner diameter measurement is an important parameter for the taper of small-bore  an inner diameter laser non-contact measuring method is presented based on the structure characteristic of the taper of small-calibre bore  which adopted optoelectronic probe sensitive device (PSD) and laser optical triangulation inspecting principle. And then  the laser probe inner diameter measuring system is designed based them. Moreover  the measuring principle  the project of optical system of this measuring system are illuminated in detail in this article. The accuracy of inspecting system is verified by experiment. The results showed that the measuring error of inspecting system is superior to 0.005  and the inspecting repetition is superior to 0.003. It indicates that the system can fulfill the inspecting accuracy demand for inspecting the taper of the small-calibre bore  and the inspecting method is applicable.
