ZHANG Yao1,WANG Bao-guang1,LI Ya-biao2,LU Hui-qing2,YU Shui-liang21.State Key Laboratory of Precision Measuring Technology and Instruments Tianjin 300072,China;2.Ji-Nan Bao De Lu Liao CO.,LTD.Jinan 250109,China  
Discuss the principle of vision sensor,the structure and model of vision system and go deep into analysis about the influence to accuracy from the structure.Based on the two dimensional binocular vision sensor measurement model,a kind of low cost single camera model used to measure coordinates in space was established.By using optical imaging,the single camera was imaged as two virtual cameras.Two parallax images which screened by the same object can be collected in the same charge coupled device(CCD)image surface.Discuss the calibration method of vision system and present a new one of the vision system with laser stripe.The precision of the instrument is appraised by National Institute of Metrology P.R.China.The performance of the apparatus is tested to be high through experiments and custom applications.
