Infrared lamp control method and device, and four-eye adjustable camera

Abstract

The embodiment of the invention provides an infrared lamp control method and a device, and a four-eye adjustable camera. The method comprises the following steps: aiming at each lens in a plurality oflenses of the multi-view adjustable camera, determining a brightness change rate between a picture shot by the lens when the first infrared lamp group is not turned on and a picture shot by the lenswhen the first infrared lamp group is turned on, wherein the first infrared lamp group is one infrared lamp group in the multi-view adjustable camera; and determining the lens with the maximum brightness change rate in the plurality of lenses as the lens bound with the first infrared lamp group. According to the method of the invention, the light supplementing effect of the first infrared lamp group is improved on the premise that the position of the first infrared lamp group is fixed.

Description

technical field [0001] The invention relates to the technical field of network cameras, in particular to an infrared lamp control method and device and a four-eye adjustable camera. Background technique [0002] The multi-camera is equipped with multiple lenses. In actual work, for scenes with low light, such as cloudy days, dark nights or places with insufficient light, infrared lenses can be used to monitor these scenes. In order to obtain a clearer image, the infrared lens can be supplemented with infrared light. [0003] In the prior art, to perform infrared supplementary light for the infrared lens on the multi-eye camera, a group of infrared lamp groups may be pre-configured for each infrared lens. When a lens needs to perform infrared supplementary light, the The lens corresponds to a pre-configured infrared lamp group, and these infrared lamp groups emit infrared light, which increases the intensity of the infrared light in the scene that the infrared lamp group can...

AI Technical Summary

Problems solved by technology

[0004] However, in a multi-eye adjustable camera where the positions of multiple infrared lenses can be adjusted manually, the positions of multiple infrared lenses may be adjusted according to actual needs, and the scene monitored by the infrared lenses will also change with this adjustment

However, due to optical and heat dissipation reasons, the infrared light group cannot follow the movement of the infrared lens. Therefore, after adjustment, the overlapping area between the scene monitored by the infrared lens and the scene that can be irradiated by the pre-configured infrared light group is small, resulting in the pre-configured The infrared light group has a poor fill light effect on the infrared lens
