The invention relates to the technical field of vehicles, in particular to a sensor position adjustment device, system and method and a vehicle. The sensor position adjustment device comprises a firstadjustment mechanism, a second adjustment mechanism, a position detection mechanism and a control mechanism, wherein the position detection mechanism can be used for detecting a current position of asensor, the control mechanism can be used for detecting whether the position of the sensor is drifted or not according to the current position of the sensor, if yes, the first adjustment mechanism and the second adjustment mechanism are controlled to drive the sensor to move, the position of the sensor is corrected, so that the position drift of the sensor is reduced or eliminated, the measurement accuracy of the vehicle sensor can be improved, and the application stability of the vehicle sensor is ensured.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a sensor position adjustment device, system, adjustment method and vehicle. Background technique [0002] On-board sensors play an important role in intelligent driving technology and are key equipment for vehicles to perceive the external environment. Currently commonly used on-board sensors include lidar, monocular camera, multi-camera, millimeter-wave radar, etc. During the working process of the on-board sensor, affected by factors such as ambient temperature and vibration, the position drift may occur after a certain period of operation, which will lead to a decrease in the measurement accuracy of the on-board sensor. Contents of the invention [0003] In the process of realizing the present invention, the inventors found that: in order to ensure the measurement accuracy of the on-board sensor, it is necessary to correct the position drift of the on-board sensor in time....
