Laser radar protecting device for driverless car based on artificial intelligence

Abstract

The invention provides a laser radar protecting device for a driverless car based on artificial intelligence. The device comprises a protective box, a protective upper cover, a laser radar, a protective mechanism and a rainproof mechanism. The protective upper cover is arranged on the protective box, the rainproof mechanism is arranged at the upper surface of the protective upper cover, a placement cavity is formed in the protective box, the laser radar is placed into the placement cavity, and the protective mechanism is arranged at one side of the laser radar; the protective mechanism comprises a protective plate, a push plate, a sliding rod and a protective spring, a movable groove is formed in the lower surface of the placement cavity, a movable block is slidably arranged inside the movable groove, the protective plate is arranged on the movable block, a protective cavity is formed in the side wall of the placement cavity, one end of the push plate is fixedly arranged at the outer side wall of the push plate, the other end of the push plate is installed inside the protective cavity through a protective spring, and a sliding groove is formed in the protective cavity. The protecting device has the advantages that the phenomenon that deviation and damage are caused by the laser radar when the car meets bumps or sharp bends can be avoided, and the device can dealt with differentweather conditions.

Description

technical field [0001] The invention relates to a protective device, in particular to an artificial intelligence-based laser radar protective device for unmanned vehicles. Background technique [0002] A driverless car is a smart car that senses the road environment through an on-board sensor system, automatically plans a driving route, and controls the vehicle to reach a predetermined target. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained from the perception, so that the vehicle can drive safely and reliably on the road. Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. In terms of working principle, there is no fundamental difference from microwave radar: a detection signal (laser beam) is sent to the target, and then the received signal reflect...

AI Technical Summary

Problems solved by technology

[0003] The laser radar is generally installed on the top of the driverless car, so there will be some disadvantages. When the driverless car encounters bumps or sharp turns, the laser radar installed on the top of the car is likely to vibrate and cause data deviation to affect driving. It is easy to vibrate and cause damage to the lidar; when it rains, if the rain covers the light emitting port of the lidar, it will affect the emission of the beam, so that the information obtained by the lidar is not accurate enough, which affects driving safety; another convenience, now Some devices cannot be adjusted and cannot meet the protection requirements of different rainfall
