Vehicle-mounted visual acquisition module, active cleaning device thereof and unmanned vehicle

Abstract

The invention relates to a vehicle-mounted visual acquisition module, an active cleaning device thereof and an unmanned vehicle. The active cleaning device of the vehicle-mounted visual acquisition module comprises a stator base, a rotating device, a light-transmitting shell, a windscreen wiper and a spray washing device, the light-transmitting shell is rotatably mounted on the stator base through the rotating device and used for covering the vehicle-mounted visual acquisition module, the windscreen wiper is arranged on the stator base, located on the outer side of the light-transmitting shell and used for being lifted up to be attached to the outer surface of the light-transmitting shell in the working process, and the spray washing device is used for spraying cleaning liquid to the outer surface of the light-transmitting shell. The outer surface of the light-transmitting shell is scraped through the windscreen wiper when the light-transmitting shell rotates, the cleaning effect is improved, the windscreen wiper is arranged on the stator base and lies down after cleaning is completed, in this way, normal shooting work of a vehicle-mounted visual collection assembly inside the vehicle-mounted visual acquisition module cannot be affected, and the reliability of the visual collection assembly is improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle-mounted vision acquisition components, and in particular, relates to a vehicle-mounted vision acquisition module, an active cleaning device thereof, and an unmanned vehicle. Background technique [0002] Usually, the outside of a vehicle such as an unmanned vehicle or a passenger car with an unmanned assistance system requires multiple vehicle-mounted vision acquisition components, such as cameras, which are used to collect and monitor the external environment of the vehicle to The driving of the vehicle provides a reference. Since the vehicle-mounted vision acquisition components are installed on the outside of the vehicle, an installation cover is usually set up to collectively install and protect multiple vehicle-mounted vision acquisition components. The distortion problem will seriously affect the processing results of computer vision, which will lead to errors in vehicle control. ...

Problems solved by technology

Since the vehicle-mounted vision acquisition components are installed on the outside of the vehicle, an installation cover is usually set up to collectively install and protect multiple vehicle-mounted vision acquisition components. The distortion problem will seriously affect the processing results of computer vision, which will lead to errors in vehicle control

In order to ensure the collection effect of the vehicle-mounted visual collection components, the current common solution is to use water washing or micro wipers to clean the outside of the installation cover. Among them, the water washing solution is to spray water mist around the installation cover through water pumps and pipelines, but this Water mist may also cause beads to hang on the installation cover or cause image distortion, especially in rainy days, the cleaning effect is not good; and the solution of the micro wiper is to drive the wiper to scrape along the circumference of the installation cover to achieve cleaning purposes, but When it comes to moving on a curved surface, the scraping effect is average, and the wiper will continue to block the camera during the movement, affecting its image acquisition, and it is easy to cause vehicle control errors
