Vehicle-mounted visual acquisition assembly and centrifugal cleaning device thereof, and unmanned vehicle

Abstract

The invention relates to a vehicle-mounted visual acquisition assembly and a centrifugal cleaning device thereof, and an unmanned vehicle. A vehicle-mounted visual acquisition system comprises a stator base, a rotating device and a light-transmitting shell. The stator base comprises an inner stand column and a first mounting table used for mounting a vehicle-mounted visual acquisition assembly, the first mounting table is fixed to the inner stand column, and the rotating device rotatably sleeves the inner stand column and can rotate at a preset rotating speed; the light-transmitting shell is rotatably installed on the stator base through the rotating device and rotates along with the rotating device at the preset rotating speed so as to generate a centrifugal force capable of cleaning dirt on the surface of the light-transmitting shell, and the light-transmitting shell and the first mounting table jointly define a cavity for containing the vehicle-mounted visual acquisition assembly; and when the rotating device rotates, the light-transmitting shell can be driven to rotate so that the dirt attached to the outer surface of the light-transmitting shell is thrown away by the centrifugal force, the effect of cleaning the outer surface of the light-transmitting shell is achieved, and a light path of the visual acquisition assembly is ensured to be clean. The vehicle-mounted visual acquisition assembly is suitable for unmanned vehicles.

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, a centrifugal 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 contro...

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
