Embodiment Construction

[0011] Such as figure 1 As shown, the anti-fogging device for automobile glass of the present invention is composed of a front-mounted vehicle camera, a machine vision analysis chip and a start-up trigger control. By analyzing the clarity of the image collected by the camera device, a standard clear imaging data is formed, and then the The image data collected in real time is compared with the standard data to determine whether the windshield of the car is in a foggy state, so as to decide whether to activate the glass blowing device spontaneously.

[0012] The camera acquisition module is pasted on the windshield before being installed on the driver's seat of the car, and performs image acquisition on the front view during driving to provide visual analysis data.

[0013] The machine vision analysis module is a simple integrated chip, which is installed on the control panel of the automobile air conditioner. When it is used for the first time, the front view is taken through...

Abstract

The invention relates to an automobile glass automatic defogging device, which comprises a camera collecting module, a machine vision analyzing module and a starting triggering module, wherein the data output end of the camera collecting module is connected with the data input end of the machine vision analyzing module, and the data output end of the machine vision analyzing module is connected with the data input end of the starting triggering module. The automobile glass automatic defogging device has the advantages that the definition degree of images collected by the camera collecting module is analyzed, and whether an automobile windshield is in a foggy state or not is judged, so whether a glass blowing and sweeping device is automatically started or not is determined.

Description

technical field [0001] The invention relates to the fields of image analysis and electronics, in particular to an automatic defogging device for automobile glass. Background technique [0002] The temperature difference between the inside and outside of the car easily causes water vapor to condense on the windshield of a car, forming a layer of mist. If it is not removed in time, it will seriously affect the driver's sight. At present, automobiles are equipped with a glass blowing device, which blows out hot or cold wind through the tuyere to make the temperature of the inside and outside of the glass similar to that of the water mist, but the device requires manual operation by the driver. When the windshield is covered with fog, the driver's vision is not clear, and he has to look for the air-conditioning switch button and perform manual operations, which seriously affects the driver's attention and poses a greater driving safety hazard. Contents of the invention [000...
