| description | 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.
