Abstract

This paper research the effect of scale using in reconstruction of industry close-range photogrammetry. The two major factor of scale using, deviation of scale reconstruction and calibration, are analyzed. Based on the analysis, the equation of deviation in scale using is obtained and verified by the experiment. According to this equation, some requests of scale using to improve the reconstruction accuracy are studied, and a new scale using method, close scale model, is proposed. Using close scale model, it can be reduced the effect of scale using deviation in reconstruction, the accuracy of industrial close-range photogrammetry is improved.
