Problems solved by technology

However, in the prior art, the scanning range and scanning resolution of the laser signal transmitting unit are usually fixed, so that the laser signal transmitting unit needs to scan the entire area in each scanning cycle to determine the position of the obstacle. As a result, obstacles cannot be tracked in time, resulting in poor tracking accuracy of obstacles

Abstract

The embodiment of the invention provides a laser scanning-based object tracking method and device. The method comprises steps: laser scanning is carried out in at least one first scanning period according to a first rule until an obstacle is scanned within a preset scanning range, a first location information set of the obstacle is determined, wherein the scanning resolution in the first rule is afirst scanning resolution, and the scanning range in the first rule is a preset scanning range; laser scanning is carried out in a second scanning period according to a second rule, and a second location information set of the obstacle is determined, wherein the next scanning period of the second scanning period is determined as a new first scanning period, the scanning resolution in the second rule is a second scanning resolution, and the second scanning resolution is higher than the first scanning resolution; and according to the first location information set and the second location information set, the trajectory information of the obstacle is determined. Thus, the obstacle tracking accuracy is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser scanning, and in particular, to a laser scanning-based object tracking method and device. Background technique [0002] At present, with the continuous development of laser scanning technology, functions such as object positioning and tracking can be realized through laser scanning technology. [0003] In the prior art, when laser scanning is required, the laser signal emitting unit is usually installed on the motor, and the laser signal emitting unit can emit laser light at different angles under the drive of the motor, so that the laser signal emitting unit can be in the Laser scanning is performed in a certain area, and by scanning a certain area, it is determined whether there is an obstacle in the area or the obstacle is tracked. However, in the prior art, the scanning range and scanning resolution of the laser signal transmitting unit are usually fixed, so that the laser...
