Problems solved by technology

[0003] At present, the most widely used laser radar is the rotary laser radar. During the research process, the inventor of the present invention found that the outer cover of the rotary laser radar can reflect and scatter the laser signal emitted by the radar, and the laser receiving unit receives the reflected , After the scattered laser signal, it will produce useless interference signal, which will affect the measurement accuracy of the laser radar

Embodiment Construction

[0031] Embodiments of the technical solutions of the present application will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present application more clearly, and therefore are only examples, rather than limiting the protection scope of the present application.

[0032] see figure 1 , figure 1 An exploded view of a lidar proposed in the present application is shown, including a top cover 1 , a body 2 , a protective cover 3 and a base 4 . The body 2 is located in the space enclosed by the top cover 1, the protective cover 3 and the base 4. The protective cover 3 is used to protect the body 2. The two can rotate relative to each other. The protective cover 3 can rotate with the base 4 relative to the body 2. It can rotate relative to the body 2 together with the top cover 1 , and can also rotate relative to the body 2 together with the top cover 1 and the base 4 . The...

Abstract

The embodiment of the present application relates to the field of laser detection technology, and discloses a laser radar and an intelligent sensing device, including: a body and a protective cover; the body is located in the protective cover and rotates relative to the protective cover; a laser emitting unit and a laser receiving unit are adjacently arranged on one side of the body, and an optical isolating plate is disposed between the laser emitting unit and the laser receiving unit. One end of the optical isolating plate is disposed on the body, and the other end faces the protective coverand extends and shifts to the side of the laser emitting unit or the laser receiving unit, and rotates relative to the protective cover. In the above manner, the embodiment of the present applicationachieves shielding and blocking of interfering laser signals, well solves the problem of crosstalk between signals due to laser signal scattering and reflection of the protective cover, and improvesthe laser radar detection accuracy.

Description

technical field [0001] The invention relates to the technical field of laser detection, in particular to a laser radar and an intelligent sensing device. Background technique [0002] With the development of technology, lidar is widely used in the field of intelligent equipment such as autonomous driving, intelligent robot navigation, and drones, and is applied to scenarios such as environmental detection and space modeling. Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of target objects. The signals are compared and processed to obtain relevant information of the target object, such as target distance, azimuth, height, speed, attitude, shape and other parameters. [0003] At present, the most widely used laser radar is the rotary laser radar. During the research process, the inventor of the present invention found that the outer cover of the rotary laser radar can reflect and scatter the laser signal emitte...
