Abstract

The embodiment of the present invention provides a method and device for protecting a camera against fog interference, and an electric appliance, and belongs to the field of electric appliances. The method includes: determining the lens temperature of the lens of the camera; determining the dew point temperature at the lens; and instructing a heating module to heat the lens according to the dew point temperature at the lens and the lens temperature. The device includes: a heating module for heating the lens of the camera; a lens temperature determination module for determining the lens temperature of the lens; a dew point temperature determination module for determining the dew point temperature at the lens; and a control module for instructing the heating module to heat the lens accordingto the dew point temperature at the lens and the lens temperature. Therefore, no fog is generated on the surface of the camera, or the fog is quickly removed after generated, thereby protecting the camera against fog interference and reducing the influence of the fog on the imaging effect of the camera.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a method and device for preventing a camera from being interfered by fog, and an electrical appliance. Background technique [0002] The country vigorously develops artificial intelligence. At present, many smart refrigerators, wine cabinets, and unmanned retail cabinets are equipped with cameras. The main purpose is to remotely monitor user behavior and image recognition, and to generate a list of items in the box in real time. Make an admin or checkout payment. [0003] When the camera is installed in refrigerators, wine cabinets and unmanned retail cabinets, due to the difference between the ambient temperature inside the cabinet and the external environment, the temperature difference is likely to cause fogging on the camera lens during the process of opening or closing the door, and the photos taken will be affected by water droplets , The clarity of pictures and videos...
