Abstract

The invention relates to a face recognition access control day and night state switching method, system and equipment and a storage medium, and belongs to the technical field of face recognition. The method comprises the steps of judging whether current environment brightness is stable or not according to an environment stability coefficient; acquiring a current day and night mode under the condition that the current ambient brightness is stable; under the condition that the daytime mode is obtained, if the ambient brightness value is smaller than a preset first ambient brightness threshold value, switching from the daytime mode to a night mode; and under the condition that the night mode is obtained, if the ambient brightness value is greater than a second ambient brightness threshold value, switching from the night mode to the daytime mode. According to the embodiment of the invention, the accuracy and stability of the day and night state switching mode can be improved, and meanwhile, the economic cost is reduced.

Description

technical field [0001] The present application relates to the technical field of face recognition, and in particular to a method, system, electronic device and storage medium for switching between day and night states of face recognition access control. Background technique [0002] At present, face recognition access control usually uses photoresistors to sense the surrounding ambient light, and changes the brightness of the fill light and image parameters according to the ambient light, and can also switch the day and night status according to the ambient light sensed by the photoresistor. However, the method of switching between day and night based on photoresistors has the following drawbacks: [0003] (1) The use of photoresistors requires additional hardware circuits, which increases economic costs; [0004] (2) The photoresistor is greatly affected by the position of the light source and is easily blocked. It cannot accurately reflect the ambient light intensity, and...
