摘要
针对一款激光成像测距系统设计激光成像自适应质心提取算法模块,该模块包含自适应积分时间调整、多波峰毛刺平滑处理及基于灰度加权的质心提取3个子模块,该模块已在FPGA上实现,处理延迟小,占用资源少,可稳定提取目标在线阵探测器上成像的质心位置,提高三维激光测距的精度.
An adaptive centroid extraction algorithm module is described. This module includes three sub modules, which are adaptive integration time adjustment, smoothness processing of multi wave crests, and extraction of centroid based on gray weighted. This module is realized on FPGA with small delay and little resource occupation. Stable extraction of centroid in the detector imaging system is beneficial to im- prove the dimensional precision of laser ranging.
