How to weaken the influence of high temperature radiation and imaging distortion on component measurement is of great significance in aerospace and automobile manufacturing. In this paper, the radiation characteristics of the object at different temperatures are analyzed based on the blackbody radiation theory, and the imaging spectral range is determined. The high temperature binocular stereo vision measurement model is established. The deflection law of light propagation in the high temperature field is analyzed by combining the finite element modeling simulation and the ray tracing algorithm, and the influence of temperature and light wavelength on the deflection of light is analyzed. Finally, through the establishment of binocular stereo vision measurement system, the interference of high-temperature radiation light is weakened by the measurement system composed of CMOS camera, narrow-band filter and parallel light source, and the analysis results are experimentally verified. The experimental results show that the measurement system can obtain clear image features at high temperature. The results of ray tracing algorithm analysis are in good agreement with the experimental data; compared with the normal temperature measurement results, the error of visual measurement results under 800 ℃ is less than 0. 28 mm, and the standard deviation of ball spacing measurement is less than 0. 11 mm, which can meet the measurement requirements of components in high temperature environment.
