摘要
激光线扫描嵌入式系统易受到基线漂移影响,扫描精度低,为了提高激光线扫描精度,提出基于嵌入式系统的激光线扫描精度优化方法。首先对激光线扫描嵌入式系统总体设计进行描述,具体设计了激光射线探测模块、传感器模块、基线漂移恢复模块和控制模块,然后进行了自适应稳态误差补偿控制器设计,对激光线扫描精度优化控制,最后进行系统调试和仿真实验分析,结果表明,本文设计的嵌入式系统的激光线扫描方法,精度高,可靠性强。
Affected by the baseline drift in the laser scanning line of the embedded system, the scan accuracy is not high. In order to improve the precision of the laser scanning line, proposes a control method of the precision opti- mization of embedded system with adaptive steady-state error compensation of laser scanning. The system includes a laser ray detection module, the sensor module, the baseline drift recovery module and control module. Then, the de- sign of adaptive controller is designed to realize the optimization control of laser line scanning precision. The embedded system integrated design includes hardware and software. Finally, the system debugging and simulation analysis results show that this method has high precision and strong reliability.
