Vehicle-mounted visual acquisition device and unmanned vehicle

Abstract

The invention relates to a vehicle-mounted vision collection device and an unmanned vehicle, and the device comprises a body part which comprises a base, a vision collection part and a lens, wherein the vision collection part and the lens are installed on the base, and the lens is located in front of the vision collection part and is rotatably installed on the base; and a shielding part which comprises a shielding cover connected with the base, wherein a light hole corresponding to the position of the visual collection part is formed in the shielding cover, the shielding part further comprises a scraping piece fixed on the shielding cover, and the scraping piece is located in a cavity between the shielding cover and the lens and can clean the surface, close to the shielding part, of the lens when the lens rotates. The scraping part is matched with rotation of the lens to clean dirt on the surface of the lens, and the automatic cleaning effect is achieved; in the self-cleaning process, the visual area of the visual collection part cannot be shielded by the scraping part, and normal work of the visual collection part is guaranteed. And the scraping part is fixed on the shielding cover and is positioned in the cavity between the shielding cover and the lens, so that the scraping part is not exposed in the external environment for a long time, and the service life is not influenced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle-mounted electronic devices, and in particular, relates to a vehicle-mounted vision acquisition device and an unmanned vehicle. Background technique [0002] Unmanned vehicles, passenger vehicles with unmanned driving assistance systems, etc. are usually equipped with multiple on-board vision acquisition devices, such as cameras, lidar, etc., which are used to collect and monitor the external environment of the vehicle and provide reference for the driving of the vehicle. Taking the camera as an example, during the driving process, dirt in the natural environment, such as rain, snow, dust, leaves, shellac, etc., will adhere to the lens of the camera, affecting the camera's acquisition of the surrounding environment, thereby affecting the driving performance and security. In related technologies, the commonly used solution is to spray glass water on the lens and then blow it off with air. ...

Problems solved by technology

Taking the camera as an example, during the driving process, dirt in the natural environment, such as rain, snow, dust, leaves, shellac, etc., will adhere to the lens of the camera, affecting the camera's acquisition of the surrounding environment, thereby affecting the driving performance and security

In related technologies, the commonly used solution is to spray glass water on the lens and then blow it off with air. This method is suitable for cleaning the floating dust or water-soluble stains on the surface. When encountering shellac, heavy rain, heavy snow, etc. Difficult to clean; the surface of the lens can also be wiped clean by using the wiper movement and spraying glass water, and the cleaning effect can be achieved by controlling the frequency of the wiper movement according to different situations, but because the moving wiper will affect the camera line of sight, it cannot start up
