Due to the reflection characteristics of the bright surface, the general three-dimensional shape measurement method are difficult to measure.To solve this problem,a scheme based on binocular vision and phase deflection method to measure the three-dimensional shape of bright surface is proposed. The binocular system layout uses the camera horizontal placement, and the complete screen-camera-adjustable platform measurement system is integrated into a custom frame.In order to reduce the calibration error, the Levenberg-Marquardt algorithm is used to optimize the position parameters obtained from the system calibration. The matching point search efficiency is improved by combining the uniqueness of the bright surface normal vector with the polar constraint of the camera.The traditional trigonometry method is improved to find the space points and the accuracy of the surface points of the object to be measured is improved. The experimental results verify that the proposed method has high measurement accuracy and stability.
