Target automatic aiming method of laser scanning measurement system

The invention relates to a target automatic aiming method of a laser scanning measurement system. The method includes: a horizontal angle of cross hair and a target central coordinate in a pixel coordinate system is obtained by employing an image processing algorithm, a horizontal angle offset of the cross hair center and the target center is calculated according to an angle offset proportional relation of the pixel coordinate system and a measurement coordinate system, and finally according to the obtained offset, the horizontal angle of the laser scanning measurement system can be set to rotate to the position of a target point. According to the method, the coordinate of the measured target is measured by employing the automatic aiming method, coordinate values of multiple measured targets in different periods can be measured, the measuring efficiency is high, the operation is simple, and the precision of measuring results is high. 本发明涉及种激光扫描测量系统目标自动照准方法，其采用图像处理算法得到的十字丝与目标中心坐标在像素坐标系下水平角，并根据像素坐标系与测量坐标系角度偏移比例
