Abstract

The invention discloses a method and a device for automatically heating and removing ice, frost and fog for a vehicle-mounted lens, and the method for automatically heating and removing ice, frost and fog for the vehicle-mounted lens. Comprising the following steps: acquiring an actual vehicle-mounted camera view, comparing the vehicle-mounted camera view with a camera image recorded in advance, detecting the environment temperature, and determining the temperature of the vehicle-mounted camera in combination with image comparison information and temperature information. And judging whether the surface of the vehicle-mounted lens is fogged or frosted, calculating the shielded area of the visual field of the vehicle-mounted camera according to the image comparison information, calculating the heat required for melting the shielded fog or frosted, and heating the surface of the vehicle-mounted lens by using the heating module. The invention provides a technology for automatically heating and removing ice, frost and fog on the surface of a camera based on images and temperature feedback of a heating element.

Description

technical field [0001] The present invention relates to the technical field of cameras, and more particularly, to a method and device for automatically heating and deicing, frosting and fogging of a vehicle-mounted lens. Background technique [0002] As the eyes of smart cars, in-vehicle cameras play a huge role in assisting driving and provide important visual information. Due to the changeable driving environment, low temperature, icy weather or some rapidly changing environment will cause the outside of the lens on the camera to freeze, fog or frost, and the vision will be blurred and cannot work properly. [0003] Therefore, it is necessary to develop a new type of vehicle camera heating device and supporting technology, which can melt the frost and fog on the vehicle lens online and keep the vision of the lens clear. SUMMARY OF THE INVENTION [0004] The primary purpose of the present invention is to address the existing problems in the prior art and provide a method...
