Paper Abstract

When the videometric method is working during a long period, the temperature effects on cameras and lens will cause changes in optical axis, focal length and aberration coefficients, so as to influence the accuracy and reliability of measurement results. The features of typical structure of camera lens when it is applied by thermal stress are analyzed in this paper. The model of key parts of camera lens which influence the measure accuracy mostly is built firstly, then the thermal stress is calculated and the influence of thermal transmutation to the measure accuracy is analyzed. Finally, suggestion to improve the structure of camera lens is proposed.
