Abstract

The present disclosure discloses a method of tracking a detector using a laser leveling instrument and a laser tracking system. This method needs to use the sector scan mode or dot mode for the laser leveling instrument, which includes: the laser leveling instrument emits laser rays to perform circular scanning; during the circular scanning, when the detector When the laser beam is detected, the detector sends a detection signal to the laser leveling instrument; when the laser leveling instrument receives the detection signal, the laser beam emitted by the laser leveling instrument moves in the opposite direction. Scanning in a circular manner; and determining that the laser leveling instrument tracks the detector when the frequency at which the laser leveling instrument receives the detection signal is greater than a first threshold. The disclosure can determine the detected position of the laser leveling instrument before calibrating the laser leveling instrument, and can accurately find the detected position without leveling the laser leveling instrument and the detector.

Description

technical field [0001] The present disclosure relates to the field of intelligent surveying and mapping, and more particularly, to a method for tracking a detector using a laser leveling instrument and a laser tracking system. Background technique [0002] The horizontal axis accuracy of the laser leveling instrument refers to the range of the angle between the laser surface of the leveling instrument and the absolute horizontal plane in each of the four directions of the front, back, left, and right of the horizontal plane when the laser leveling instrument is normally leveled and scanned on the horizontal plane. According to geometric principles, the accuracy of the horizontal axis is also often expressed as the range of height values ​​from a certain distance. [0003] The existing methods for calibrating the laser leveling instrument are all suitable for calibrating the laser leveling instrument in the rotation scanning mode. Since the detector needs to distinguish the ...
