Abstract

The invention relates to the field of electronic technology and especially to a target positioning method using laser scanning and a laser receiving device. The method comprises steps that the laser receiving device records a first time when a synchronization signal transmitted from a first laser rotation scanning device is received, and a second time when a laser signal is received, determines a reception time length, determines the rotation angle of the first laser rotation scanning device according to the reception time length, determines the position of the laser receiving device (the same as the position of a target object) according to the rotation angles of N laser rotation scanning devices. The first laser rotation scanning device is any one of the N laser rotation scanning devices of a laser emission device, wherein N is greater or equal to 3. The method may position the laser receiving device just with at least three laser rotation scanning devices, does not have high requirements for light, mechanicals, and electrics. The number of laser sensitive element in the laser receiving device is at least one so that the laser receiving device is simple in structure.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a target positioning method using laser scanning and a laser receiving device. Background technique [0002] Positioning technology is a supporting technology for applications such as location-based services and virtual reality. In order to improve user experience, the requirements for positioning accuracy and real-time performance are getting higher and higher. Due to its monochromaticity and good directionality, laser is one of the main technical means to achieve precise positioning of targets. At present, the main methods of laser for target positioning and tracking are: [0003] 1) Based on the method of measuring laser time of flight (ToF, Time of Flight), typical applications include laser range finder, 2D (2dimensional, two-dimensional) laser radar, and 3D (3dimensional, three-dimensional) laser radar. This method requires accurate timing within nS (nanosecond) leve...
