Abstract

The invention provides a camera focusing processing method and device, a storage medium and an electronic device, and the method comprises the steps: collecting a target image under the irradiation ofmixed light in a current monitoring environment in a night mode through a camera; acquiring a first exposure parameter of the camera under the irradiation of the mixed light and a first relative distance and a second relative distance in a BG and RG color space; determining a visible light brightness value of the target image according to the first exposure parameter, the first relative distanceand the second relative distance; under the condition that the visible light brightness value is smaller than a predetermined first visible light brightness threshold value triggering focusing, triggering the camera to perform focusing, so the problem of image blurring caused by infrared non-confocal when the camera is switched to a night mode too early in the prior art can be solved; focusing istriggered when the brightness of the visible light meets a predetermined focusing triggering threshold value, so that repeated debugging is avoided.

Description

technical field [0001] The present invention relates to the technical field of monitoring equipment, in particular to a camera focus processing method, device, storage medium and electronic device. Background technique [0002] At present, the field of security monitoring is in full swing, and one of the more important technical fields is the movement. The movement lens has developed rapidly over the years, from short focus to long focus, and then to super long focus, from small magnification to super large magnification, and resolution from 720p to 1080p to 400w and 4k, etc. The combination of movement and dome camera can realize all-weather Multi-directional and multi-dimensional monitoring is very promising. During the research and development process of the movement, the zoom lens will blur the picture due to the misalignment of the imaging focal planes of visible light and infrared light. This phenomenon is called infrared non-confocal. [0003] In general, the moveme...
