Image light supplementing method and device and computer readable storage medium

Abstract

The invention discloses an image light supplementing method and device, and a computer readable storage medium. The image light supplementing method comprises the steps of obtaining a target distance between a target object and an image acquisition device, and a current light supplementing brightness value of a light supplementing device for supplementing light to the target object; in response to the fact that the target distance is smaller than a first distance threshold value, reducing the current light supplementing brightness value to obtain an adjusted light supplementing brightness value; and carrying out light supplement on the target object by utilizing the adjusted light supplementing brightness value. In this way, the light supplementing brightness value of the light supplementing device can be automatically adjusted according to the distance, and the image effect is better.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an image supplementary light method, equipment and a computer-readable storage medium. Background technique [0002] With the development of artificial intelligence, computer vision is being widely used in various scenarios in life, among which the field of security monitoring is an important application field of computer vision. In the field of security monitoring, the actual effect of computer vision is largely limited by the image quality collected by surveillance cameras. The higher the image quality, the better the actual effect of computer vision. While surveillance cameras have higher requirements on lighting conditions when collecting images, usually the better the lighting conditions are, the higher the quality of the collected images will be. Therefore, when the light is not sufficient at night, the external fill light of the surveillance camera is usually turned on ...

Problems solved by technology

[0003] When there is a moving object close to the monitoring equipment, due to the illumination of the supplementary light, the reflection of the object is very likely to occur, resulting in the brightness of the nearby object being very bright, and the brightness of other areas is very dark. Therefore, if the brightness of the supplementary light cannot be reasonably controlled, it may It will cause the picture effect to become worse in some scenarios

Although the existing fill light intensity adjustment technology can realize the adjustment of the overall brightness of the captured image, there are still some scenes where the image effect is not good.
