Laser swinger detector assembly and method for estimating swinger laser position

Abstract

The invention provides a laser swinger detector assembly and a method for estimating a swept laser position. The laser swinger detector assembly is composed of four photoelectric detection units whichsurround the supporting frame by 360 degrees and are perpendicular to each other in pairs. The laser swinger detector assembly estimates the distance of the swept laser through the pulse time interval and the scanning period of the two adjacent photoelectric detection units; an optical signal output by a laser swinger is received through a photoelectric detection unit, light intensity informationand light intensity variation are output through a data processing module, and azimuth information of the laser swinger can be obtained after calculation. According to the elevation function of the photoelectric detection unit, the height of the leveling laser is estimated through a gravity center method. The laser swinger has the advantages that the laser swinger has a sweeping function, information such as the distance, the direction and the height of sweeping laser can be estimated, extra measuring instruments are reduced, meanwhile, the accurate control degree of engineering operation equipment is improved, and the laser swinger is easy to operate, high in work efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of building surveying and detecting instruments, and in particular relates to a laser leveling instrument detector assembly and a method for estimating the position of a leveling laser. Background technique [0002] The laser leveling instrument is driven by the fast rotating shaft to make the visible laser point sweep out the light at the same level, which is convenient for engineers to locate the level. [0003] The laser leveling instrument is a surveying and mapping instrument integrating optical, mechanical, electronic and other technologies. It can provide a horizontal reference plane for engineering applications. Cooperating with the detector, it can control the horizontal height of any measuring point within the test range, and can measure Combined with construction to realize construction automation, it is widely used in building construction, leveling ground, airport construction, etc. [0004] Ho...

Problems solved by technology

[0004] However, in order to achieve precise control of engineering equipment, it is usually necessary to control the target's height, azimuth, distance and other information, while the laser leveling detector only has the function of height measurement, and often requires additional instruments to measure the target's azimuth and distance, and the number of instruments The increase is not only cumbersome to operate, but also not conducive to the progress of engineering operations.
