Vehicle-mounted visual acquisition module and its centrifugal cleaning device, unmanned vehicle

Abstract

The present disclosure relates to a vehicle-mounted visual collection assembly, a centrifugal cleaning device thereof, and an unmanned vehicle. The vehicle-mounted visual acquisition system includes a stator base, a rotating device, and a light-transmitting casing. The stator base includes an inner column and a first mounting platform for installing the vehicle-mounted visual acquisition component. The first mounting platform is fixed on the inner column, and the rotating device It is rotatably sleeved on the inner column and can be rotated at a preset speed. The light-transmitting housing is rotatably installed on the stator base through the rotating device, and rotates at a preset speed with the rotating device to generate light that can clean and transmit light. Due to the centrifugal force of the dirt on the surface of the casing, the light-transmitting casing and the first mounting platform together enclose a cavity for accommodating the vehicle-mounted visual collection component. When the rotating device rotates, it can drive the light-transmitting casing to rotate, so that the dirt attached to the outer surface of the light-transmitting casing is thrown away by centrifugal force, so as to clean the outer surface of the light-transmitting casing and ensure the optical path of the visual collection component is clean. The in-vehicle vision acquisition component is suitable for unmanned vehicle applications.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle-mounted visual acquisition components, and in particular, to a vehicle-mounted visual 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 on-board visual acquisition components, such as cameras, etc., which are used to collect and monitor the external environment of the vehicle, in order to The driving of the vehicle provides a reference. Since the vehicle-mounted visual acquisition components are set on the outside of the vehicle, a mounting cover is usually installed to centrally install and protect multiple vehicle-mounted visual acquisition components. However, when the mounting cover is exposed to the outside world, it is easy to absorb dust, rain and other contaminants, which will cause pho...

AI Technical Summary

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
