摘要:
在采用线结构光投影的三维物体测量中, 激光条纹中心检测是影响测量精度及系统分辨率的一个重要因素.提出了一种激光条纹中心检测方法,这种方法通过对极值法获得的中心点的拟合,计算出光条各处的法线方向,并在法线截面上用遗传算法进一步优化出灰度的极大值点.实验结果表明在合理选择遗传算法的交叉率和变异率的情况下, 该方法可以有效地获取光条纹中心,满足系统精度要求.
Abstract:
Detecting the structured light strip center is one of the important factors influencing measure precision and system resolution of 3D measurement based on line structured light. A new centreextracted method that combines genetic algorithm with extremum method is proposed in this paper. This method fits the central points resulted from extremum method and gets each normal direction of them, then optimizes the extremum by genetic algorithm on each section. Experimental results show that with the adaptive rate of crossover and aberrance properly selected for genetic algorithm, the structured light strip center line can be accurately acquired with satisfied accuracy by adopting this method.
