摘　　要：针对普通单光源单接收器传感器普遍存在的反射光线遮蔽现象,提出了一种自动消除光线遮蔽的方法和测点快速重定位算法.它是通过变换传感器空间姿态使发射光线避开遮挡物,并采用重定位算法重新标定测量坐标系,从而实现高效高精度测量.实验验证表明,该方法简单实用,具有一定的参考价值.Aiming at the beam occlusion of a single emitter and single receptor laser sensor, an automated approach for avoiding occlusion during measuring process was presented. Through changing the position and pose of the laser sensor, occlusion can be automatically avoided with high precision. And based on a triangular pyramid, an efficient repositioning method was also put forward to ensure that all data are in the same measuring coordination.
