Abstract Aiming at the problems of lens eccentricity due to manual adjustment during lens detection, a technical solution for measuring the lens by combining Hartmann detection method, machine vision technology and stepper motor control system is proposed. Based on this scheme, an automatic lens detection system is designed and manufactured. By analyzing the real-time size and position of multiple light spots, the host computer communicates with the microcontroller to control the movement of the mechanical module, thereby automatically calibrating the lens position and measuring the lens. -15m-1~+15m-1 spherical lens is used for repeatable measurement. The experimental results show that the system achieves full-automatic lens measurement, and the test results meet the requirements of national metrological standards. Measurement error is less 0.02m-1 than manual measurement results, the accuracy is improvemented.
