Method for preventing lens from fogging, intelligent control equipment and automatic driving vehicle

Abstract

The invention provides a method for preventing a lens from fogging. The method for preventing the lens from fogging comprises the steps of acquiring the current position and the current time of an automatic driving vehicle; acquiring driving data of the automatic driving vehicle and first environment data of the automatic driving vehicle at the current position; determining an expected position and expected time to be achieved in the driving process of the automatic driving vehicle according to an expected path; obtaining second environment data associated with the expected position and the expected time; obtaining environmental difference data according to the first environment data and the second environment data; judging whether the environmental difference data meets a preset fogging condition or not according to a preset fogging standard; and when the environmental difference data meets the preset fogging condition, starting an anti-fogging scheme corresponding to the environmental difference data. By starting the anti-fogging scheme in advance, the lens is actively prevented from fogging, and the safety of the automatic driving vehicle in the driving process is improved. In addition, the invention further provides intelligent control equipment and the automatic driving vehicle.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method for preventing lens from fogging, an intelligent control device and an automatic driving vehicle. Background technique [0002] Camera equipment is an important sensor on a self-driving vehicle, which can collect image data around the self-driving vehicle to identify obstacles and other road signs around the self-driving vehicle. The self-driving vehicle adjusts the trajectory and pose of the self-driving vehicle according to obstacles and other road signs to ensure the driving safety of the self-driving vehicle. [0003] However, during the driving process of the self-driving vehicle, some specific environmental changes will cause the lens on the camera device that collects images to fog up, so that the line of sight of the camera device is blocked and the surrounding environment cannot be collected. Although existing self-driving vehicles also have methods f...

Problems solved by technology

[0003] However, during the driving process of the self-driving vehicle, some specific environmental changes will cause the lens on the camera device that collects the image to fog up, so that the line of sight of the camera device is blocked and the surrounding environment cannot be collected.

Although existing self-driving vehicles also have methods for solving lens fogging, the existing method for solving lens fogging is generally to solve how to remove the fogging of the lens, that is, take corresponding measures to eliminate the fogging of the lens of the camera equipment. The fog on the lens will cause the camera equipment that collects images to be unable to collect image data of the surrounding environment for a period of time

While the self-driving vehicle is driving, the section of the road that loses the view of the camera equipment will lack a lot of real-time information, making it impossible for the self-driving vehicle to perceive danger in time

The above situation is very dangerous in the process of driving a self-driving vehicle
