Intelligent space positioning system and space positioning method for laser pan-tilt

Abstract

The invention discloses an intelligent space positioning system and space positioning method for a laser pan-tilt. The space positioning system comprises a distance acquisition subsystem, an angle control subsystem and a marker subsystem, wherein the distance acquisition subsystem comprises a probe array formed by laser ranging probes; the probe array follows the marker subsystem and monitors distance information between the probe array and the marker subsystem from the same direction; each laser ranging probe collects independent distance information separately; the angle control subsystem controls a level angle and a pitch angle of the distance acquisition subsystem and makes the distance acquisition subsystem aligned at the marker subsystem; and the marker subsystem provides the distance acquisition subsystem with an alignment signal, receives alignment measurement operation of the distance acquisition subsystem and is matched with correction lock operation of the angle control subsystem. According to the system, large-range measurement and accurate positioning can be achieved by employing laser ranging, meanwhile, the anti-jamming capability of equipment is improved, and the measurement accuracy can be further improved by using the space positioning method.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a laser pan-tilt intelligent space positioning system and a space positioning method. Background technique [0002] In the existing wireless communication ranging equipment, it is mainly composed of four parts: three wireless signal transmitting and receiving points on the ground and one wireless signal transmitting and receiving point in the air. Its main principle is to use the divergent propagation of radio waves, measure the time of several sending and receiving points, and calculate the distance information of each sending and receiving point. Then by bringing it into the calculation, the relative position information of the sending and receiving points in the air is obtained. [0003] When the above technology is used for large-scale testing and positioning measurement, there are the following problems and shortcomings: [0004] (1) The measurement accuracy of the existin...

AI Technical Summary

Problems solved by technology

[0004] (1) The measurement accuracy of the existing technology is low. The main problem is that the technology of the hardware components is limited. The spatial positioning of the moving object will be inaccurate due to the untimely response of the hardware. At the same time, the influence of radio wave interference will increase the use of the site. limitations

In the actual use of radio waves, due to hardware reasons, the precise positioning cannot meet the actual requirements, and the measurement accuracy cannot be satisfied;

[0005] (2) The use of the existing technology is relatively inconvenient. The existing technology requires four transceiver modules to operate at the same time to realize the positioning of the spatial position. Correspondingly, it is inconvenient to deploy and recover equipment at multiple points at the beginning of the measurement. ;

[0006] (3) The fatal shortcoming of the existing technology is that the practical radio wave communication measures the distance information of each sending and receiving point, which is limited by the error of the hardware equipment, the measurement accuracy cannot meet the needs of precise surveying and mapping, and the spatial positioning cannot reach the required precise value

In addition, during wireless signal transmission, measurement signal loss will occur due to the inability to synchronize the movement of the transceiver antenna.
