Abstract

The invention discloses a target positioning method using laser scanning. The method includes the following steps that: as for any one of the N laser rotational scanning devices of a laser emitting device, first reference time and second reference time are determined from each scanning period of the laser rotational scanning device; a laser receiving device determines the first motor rotation angular velocity of the laser rotational scanning device corresponding to first time according to the first reference time, the second reference time, the first angle of preset angle synchronization signals corresponding to the first reference time, and the second angle of preset angle synchronization signals corresponding to the second reference time; the rotation angle of each laser rotational scanning device is obtained through calculation; and the laser receiving device determines a position where the laser receiving device is located according to the rotation angles of the N laser rotationalscanning devices and the coordinates of the N laser rotational scanning devices.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a target positioning method and device using laser scanning. 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. Among them, based on the method of measuring the angle of arrival (AoA, Angle of Arrival) of the laser, the characteristic of good directivity of the laser is used to measure the angle of arrival of the laser, and then use the AoA method to locate the target. In this method, multiple laser sensitive components are installed on the target to measure the time when the laser light reaches the sensor re...
