Automatic rearview mirror heating method and device

Abstract

The embodiment of the invention provides a rearview mirror automatic heating method and device, and the method comprises the steps: collecting the camera data of a vehicle owner through a camera device, and obtaining the sight direction of the vehicle owner in the camera data when the vehicle is driven; when the sight line direction is the rearview mirror direction, detecting whether the duration of keeping the sight line direction by the vehicle owner is greater than a preset duration or not; when the duration of keeping the sight direction of the vehicle owner is longer than a preset duration, collecting the facial expression of the vehicle owner through a camera device, and performing micro-expression analysis on the facial expression to obtain a micro-expression analysis result; a preset vehicle owner micro-expression set is obtained, the micro-expression analysis result is compared with the vehicle owner micro-expression set, and when the micro-expression analysis result is matched with the vehicle owner micro-expression set, a rearview mirror heating device is started to heat a rearview mirror. By the adoption of the method, the rearview mirror heating device can be started more intelligently according to the requirements of a car owner, and then energy is saved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a rearview mirror automatic heating method and device. Background technique [0002] During the driving process of the vehicle, the vehicle rearview mirror is an important part of the vehicle. The driver needs to see the rear or side road conditions clearly through the rearview mirror. However, in rainy, snowy and foggy weather, or the vehicle rearview mirror itself If it is not clean, it will affect the driver's judgment on the road conditions. At this time, it is necessary to heat and clean the rearview mirror. [0003] However, in the actual driving process, in the case of the same blurring degree of the rearview mirror, the experienced driver can complete the driving, but the novice driver cannot. However, the current heating devices are basically activated by external environmental factors. Detecting whether heating is needed is sometimes a waste of energy and not smart en...
