Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0022] Please refer to the example figure 1 and 2 , shows a multi-line rotary laser radar device 100 provided in the first embodiment, including a rotary drive mechanism 10, a rotary frame 20 and at least one set of lasers, each set of lasers includes a plurality of lasers 31 and is installed in multiple directions On the rotating frame 20, the laser scanning surfaces of the lasers 31 intersect in pairs to form a predetermined angle when rotating, and the rotating drive mechanism 10 is connected to the rotating frame 20 to drive the rotating frame 20 to rotate each laser 31. Multiple lasers 31 perform laser scanning from multiple different angles.

[0023] Specifically, the above-mentioned components are accommodated in the casing 11, and the casing 11 includes an upper cavity 111 and a lower cavity 112. Preferably, the upper cavity 111 is tran...

Abstract

The invention relates to a multi-line rotary type laser radar apparatus comprising a rotary driving mechanism, a rotary rack and at least one group of laser devices, wherein each group of laser devices comprise a plurality of laser devices and are mounted on the rotary rack in a plurality of directions, every two laser scanning faces of the laser devices during rotation are intersected with each other to form a preset angle, the rotary driving mechanism is connected with the rotary rack so as to drive the rotary rack to rotate, all the laser devices are enabled to rotate, and laser scanning isperformed from different angles via the plurality of laser devices. A rotary structure is adopted in the above multi-line rotary type laser radar apparatus, a laser scanning plane can be formed wheneach laser device is used for scanning, the plurality of laser devices are arranged according to rules, planes of different angles can be scanned at the same time in a plurality of directions, good 3Dlaser scanning effects can be exerted via a small amount of laser, a rapid and highly efficient scanning mode is adopted, and three dimensional laser scanning is realized; the apparatus can be widelyapplied to the fields of driving assistance systems, unmanned driving systems, mobile robots, pilotless aircraft obstacle avoidance, navigation and the like.

Description

technical field [0001] The invention relates to the technical field of laser scanning, in particular to a multi-line rotary laser radar device. Background technique [0002] With the development of laser technology, laser scanning technology is more and more widely used in surveying, transportation, driving assistance and drones, mobile robots and other fields. Existing laser scanning radars generally have high manufacturing costs and complex structures, and some have large volume and mass, which is not conducive to the application of laser radar in driving assistance systems, unmanned driving systems, mobile robots, unmanned aircraft obstacle avoidance and Applications in the field of navigation. [0003] Laser scanning is mainly through the rapid and continuous emission of multiple pulses. The direction of these emission changes continuously in a certain way, and each distance measurement value is regarded as a pixel. The collection of fast and continuous emission and r...
