Abstract

The present invention belongs to the laser radar field and provides a laser radar acquisition and ranging apparatus. The laser radar acquisition and ranging apparatus includes a laser output device which is used for outputting collimated laser, a laser scattering device which is arranged on the laser path of the laser output device and is used for scattering the collimated laser to 360-degree ring-shaped laser, and image sensing devices which are arranged around the laser output device and can receive laser signals reflected by a measured object in an all-direction manner. With the laser radar acquisition and ranging apparatus adopted, 360-degree full-angle signal acquisition can be realized, and angle resolution and scanning frequency can be improved.

Description

technical field [0001] The invention belongs to the field of laser radar, and in particular relates to a laser radar acquisition and ranging device and a working method thereof. Background technique [0002] Lidar is an advanced detection method combining laser technology and modern photoelectric detection technology. It can accurately measure the distance and orientation information of the target position, and it is more and more used in the defense industry and all aspects of smart life. [0003] At present, when using lidar detection, it is usually realized by mechanical rotating components, that is, placing the laser on a rotating platform that can rotate at a constant speed, and at the same time controlling the laser to emit laser beams to scan and detect objects in front, and record the corresponding orientation information, through image sensing The unit receives the laser beam reflected by the detected object, and determines the imaging position of the reflected lase...
