Abstract: Considering the lack of ground control data of domestic remote sensing images,a method of using reference image data geo-positioning to increase accuracy of geo-positioning was proposed.Meanwhile,considering random errors in coefficient matrix of observation equation for image points,the total least squares was introduced to achieve a more reasonable result.The experimental results of ZY-3 and TH-1 images indicated the feasibility and availability of proposed method.

Key words: remote sensing images, RFM, block adjustment squares, reference image
