Windscreen wiper control method and related device, component, system, equipment and medium

Abstract

The invention relates to a windscreen wiper control method and a related device, component, system, equipment and medium. The windscreen wiper control method comprises the following steps: carrying out image recognition on images shot by a visual sensing device according to a set image acquisition period; if the shielding position of the windscreen wiper is recognized from one frame of image, determining the movement time of the windscreen wiper from the shielding position to the outside of the shooting view of the visual sensing device; according to the movement time and the working period of the windscreen wiper, a control instruction used for controlling the windscreen wiper to start working is generated, so that when the windscreen wiper is controlled to be in the shooting view field of the visual sensing device, the visual sensing device is in a non-shooting state; wherein an incidence relation exists between the work period and the image acquisition period. The visual sensing device solves the problem that the windscreen wiper shields the visual sensing device, and the visual perception capability is improved.

Description

technical field [0001] The embodiments of this specification relate to the technical field of automation control, and in particular to a wiper control method and related devices, components, systems, equipment and media. Background technique [0002] In the application field of automatic intelligence, the perception system plays a vital role, and visual perception is a key component of the perception system. For example, sweeping robots, service robots, logistics robots, vehicles, drones, etc. are generally equipped with visual sensing devices (such as cameras, cameras, etc.) for image acquisition, and image analysis and processing to achieve visual perception. [0003] But in outdoor environments, visual perception is easily affected by the environment. For example, for self-driving vehicles equipped with cameras, in rainy, snowy and other bad weather scenarios, it is necessary to configure the camera with a wiper to remove the raindrops on the glass outside the camera len...

[0003] But in outdoor environments, visual perception is easily affected by the environment

For example, for self-driving vehicles equipped with cameras, in rainy, snowy and other bad weather scenarios, it is necessary to configure the camera with a wiper to remove the raindrops on the glass outside the camera lens, so as to ensure that there will be no large raindrops in the images collected by the camera. The inventor found that when the wiper is working, it is easy to block the camera lens, and the main reason for the blockage of the wiper is that the existing camera and the wiper work independently. When the operating frequency of the wiper and the operating frequency of the camera are not adjusted in advance, It is easy for the wiper to block the camera lens. If the continuous multi-frame images captured by the camera are blocked by the wiper, it will greatly affect the visual perception of the autonomous vehicle.
