JIN Yi,ZHAI Chao,XING Xiao-zheng,TENG Yong,HU Hong-zhuan(University of Science and Technology of China,Hefei,Anhui 230027,China)  
A set of non-contact on-line detection system based on close-range photogrammetry is designed,which can detect multi-objects simultaneously in the wide field of view compared to the traditional measuring methods.The detection precision is increased through some key technologies such as precise calibration of CCD camera,light rays adjustment method,subpixel image processing technology and corresponding image points matching.The single frame photo-field is about 141?mm and 500?mm×500?mm area is finally covered,the precision of space coordinates detection is less than 0.03?mm.This system has the potential in precision measurement,industry measurement and other application areas.
