摘　　要：针对传统光电三维检测系统存在检测精度低的弊端,设计基于嵌入式技术的光电精密检测系统。系统通过激光扫描光学系统采集光电脉冲信号,光电脉冲信号通过输入脉冲细分电路进行细分转换处理,细分后的光电脉冲信号传输到CPU控制器中AVR单片机进行处理后,实现光电信号采集和控制,通过畸变校正方法对光学畸变进行校正。实验结果表明,该系统可实现高精度、高效率的光电检测。Aiming at the drawback of low accuracy of traditional photoelectric 3D detection system,a photoelectric precision detection system based on embedded technology is designed. The system uses the laser scanning optical system to collect the photoelectric pulse signal. The photoelectric pulse signal is subdivided and converted through the input pulse subdivision circuit. After the subdivision,the photoelectric pulse signal is transmitted to the AVR microcontroller in the CPU controller,and the photoelectric signal is collected and controlled. The optical distortion is corrected by the distortion correction method. The experimental results show that the system can realize photoelectric detection with high accuracy and high efficiency.
