【Abstract】 CIS(contact image sensor) is the conventional sensor in the field of image scanning. In the application of concrete engineering, the image acquisition schemes of CIS sensor have many differences, and the performance is also uneven. Aiming at solving the problem of CIS high-speed acquisition, this paper proposes a new way, which has advantages compared with traditional solutions, such as good generality, high acquisition speed, easily expanded, low cost, and so on. This paper discusses in detail design plan of CIS high-speed image acquisition based on CPLD, and has full analysis on experimental results.更多还原
