Abstract

The invention discloses a laser scanning detection device and method capable of adaptively adjusting a scanning angle. The laser scanning detection device comprises an angle adjusting device, a laserscanning detection device body, a main control module and a shell assembly. In the target laser scanning process, echo signals are transmitted to the main control module to calculate the included angle between the axis of a rotating motor and a target movement direction under vertical projection, the minimum pulse number of a stepping motor is calculated through an optimal angle model, the angle adjusting device is controlled to change the axis direction of the rotating motor, so that the axis of the rotating motor is parallel to the vertical projection of the target movement direction, and the laser line scanning direction of the detection device is changed to obtain more accurate and stable target characteristics. The problem that a traditional laser scanning detection device has an obstacle blind area due to a fixed scanning angle is solved, and the recognition rate and the detection efficiency of target detection are improved.

Description

technical field [0001] The invention belongs to the field of laser detection, and in particular relates to a laser scanning detection device and method for adaptively adjusting a scanning angle. Background technique [0002] The laser scanning detection device is an active detection and imaging system that can accurately and quickly obtain the three-dimensional space information of the target. Due to the advantages of high coherence, directionality, and monochromaticity of the laser, the laser scanning detection device can achieve long-distance and high-precision fast ranging function. The laser scanning detection device is mainly composed of a transmitting system, a receiving system, and an information processing system. , Signal amplification and processing, the target distance, azimuth, height, speed, attitude and other information can be obtained through laser ranging technology, and the information processing system processes these information to detect, identify and t...
