Problems solved by technology

These three installation positions have different disadvantages: the overhead installation method leads to greater constraints on the design of the upper body of the robot, and there is a large blind area for the detection of low-level obstacles; the front-side installation method reduces the usable angle of the 360-degree laser At least 90 degrees, the appearance design is also relatively abrupt; the installation method of the middle interlayer is to place the multi-line laser radar in the middle hollow interlayer, which can retain a 360-degree range, but in order to retain the upper and lower viewing angles, the height of the middle interlayer needs to be very high, and the structure The window is too large, and the space is seriously wasted

Embodiment 1

[0053] This embodiment provides a multi-line laser radar constraint adjustment system, the multi-line laser radar is, for example, 8-line, 16-line, 32-line laser radar, etc., including an upper housing 400, an upper reflection device 100, a lower housing 500 and a lower Reflecting device 200;

[0054] The upper housing 400 is connected above the multi-line laser radar 300 , and the end of the upper housing 400 located in front of the transmitting part 301 of the multi-line laser radar 300 is connected vertically downward with a first vertical wall 401 ;

[0055] The lower housing 500 is connected to the bottom of the multi-line laser radar 300 , and the end of the lower housing 500 located in front of the transmitting part 301 of the multi-line laser radar 300 is connected vertically upward with a second vertical wall 501 ;

[0056] The upper reflection device 100 is fixedly connected to the lower end surface of the first vertical wall 401, and is used to reflect once or more ...

Embodiment 2

[0061] This embodiment provides a multi-line laser radar constraint adjustment system, on the basis of the above embodiments, such as image 3 As shown, the upper plane reflector 101 and the lower plane reflector 201 are changed to be inclined and arranged at an angle, and they respectively reflect the uppermost part of the scanning light and the lowermost part of the scanning light emitted by the emitting part 301 once. Therefore, the irradiation range of the reflected light is expanded, and the detection range is expanded.

Embodiment 3

[0063] This embodiment provides a multi-line laser radar constraint adjustment system, on the basis of the above embodiments, such as Figure 4 As shown, the fixed connection between the upper reflection device 100 and the lower end surface of the first vertical wall 401 is replaced by a telescopic connection; the fixed connection between the lower reflection device 200 and the upper end surface of the second vertical wall 501 is replaced by a telescopic connection. Thus, the gap between the upper reflector 100 and the lower reflector 200 can be adjusted to realize the angle θ 1 and θ 2 adjustable. And through the telescopic connection between the upper reflection device and the upper casing and between the lower reflection device and the lower casing, the forward and backward movement adjustment of the viewing angle α is realized, and the detection range is expanded.

[0064] Preferably, the upper reflection device 100 further includes a first retractable device 105 ; the u...

Abstract

The invention discloses a multi-line laser radar constraint adjustment system and a detection method, and relates to the technical field of intelligent robots. The system comprises an upper shell, an upper reflection device, a lower shell and a lower reflection device; the upper shell is connected and positioned above the multi-line laser radar, and the end part of the upper shell is downwards and vertically connected with a first vertical wall; the lower shell is connected below the multi-line laser radar, and the end part of the lower shell is vertically connected with a second vertical wall upwards; the upper reflecting device is connected with the lower end surface of the first vertical wall and is used for reflecting the uppermost part of scanning light emitted by the emitting part; and the lower reflecting device is connected with the upper end surface of the second vertical wall and is used for reflecting the lowest part of scanning light emitted by the emitting part. On the premise of not losing data and visual angles, the structure windowing size is reduced, and miniaturization is facilitated.

Description

technical field [0001] The invention relates to the technical field of intelligent robots, in particular to a multi-line laser radar constraint adjustment system and detection method. Background technique [0002] With the development of artificial intelligence and the reduction of key hardware costs, robots have also been more widely used. In robotics, mapping and positioning technology is one of the core technologies. At present, the laser radar SLAM technology is usually used for robot mapping and positioning. Due to the advantages of multi-line laser radar (such as 16-line, 32-line, etc.) ranging distance, more data, and higher cost performance, it is widely used indoors and outdoors. Scenarios such as robots and driverless cars. [0003] Lidar is an infrared laser ranging radar based on the principle of TOF (time-of-flight ranging). Lidar is an active detection and does not depend on external lighting conditions or the radiation characteristics of the target itself. It...
