A high-precision long-distance laser receiving sensor positioning method and system

Abstract

The embodiment of the invention discloses a high-precision long-distance laser receiving and sensing positioning method and system. Wherein, the method includes that the processor receives the electrical signal sent by the photoelectric sensor array, and the electrical signal is obtained by converting the laser signal emitted by the laser transmitter collected by the photoelectric sensor array; the processor uses the electrical signal to calculate the laser beam according to the mode selection instruction input by the user The position information of the center point of the plane irradiated on the photosensor array. Wherein, the array direction of the photoelectric sensor array is perpendicular to the plane where the laser beam emitted by the laser emitter is located. This application greatly improves the positioning accuracy of the laser information output by the laser transmitter on the laser receiver, and has a wider application range; the high-precision positioning of the application makes it possible to meet the requirements without subsequent processing, thereby reducing the cost of subsequent processing; The anti-interference performance is greatly improved, the environment adaptability is strong, and the conditions are more relaxed; the requirements for the laser transmitter are not high, and the cost of the transmitter is greatly reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of laser technology, in particular to a high-precision long-distance laser receiving sensor positioning method and system. Background technique [0002] With the rapid development of laser technology, various equipment prepared by using laser technology is gradually popularized and applied in all walks of life. In the equipment prepared by laser technology, the basic components include a laser transmitter and a laser receiver. The laser transmitter emits a planar pulsed laser beam, and the receiving sensor of the laser receiver receives the laser emitted by the laser transmitter, and the light carried by the laser beam The information is analyzed and processed to obtain the required information for use by other subsequent circuits. It can be seen that the performance of the laser receiver determines the performance of the entire laser system. [0003] For example, the dual-axis slope single (tw...

Problems solved by technology

The price is opaque and expensive, which leads to the high market price of the laser system. The high price limits the universality of the laser system. How to control the manufacturing cost of the laser system is very important

[0005] For existing laser receivers, in some actual high-precision applications, the positioning equipment with low precision needs post-processing to meet the requirements, which consumes a lot of manpower and material resources, resulting in high follow-up maintenance costs; In the working condition with a large effect, the external light source reflected or scattered to the receiver will seriously interfere with the processing of the received laser signal by the laser receiver, and the requirements for the output laser information quality of the laser transmitter are relatively high, correspondingly increasing the overall Supporting facility costs for laser systems
