A three-dimensional intelligent supplementary light system and method

Abstract

The invention provides a three-dimensional intelligent supplementary light system, comprising: several supplementary light lamps with different projection angles; a PWM control circuit whose output end is connected to the supplementary light lamp; a processor connected to the input end of the PWM control circuit, and also includes a The input end of the processor is connected to the image forming device. The present invention is provided with multiple groups of supplementary lights, and the projection angles of each group of supplementary lights are different, and there is a fixed angle between the supplementary lights and the image imaging sensing device, so that the supplementary lights form a three-dimensional layout; the image The imaging device captures the change information of the external environment, converts the signal through the processor and modulates it with the PWM control circuit to realize the intelligent adjustment of the brightness of the corresponding supplementary light, which avoids the fisheye camera from being monitored due to unreasonable supplementary light and changes in environmental factors. The problem of poor image quality achieves the purpose of intelligent light supplement for fisheye cameras.

Description

technical field [0001] The invention relates to the field of safety monitoring, in particular to a three-dimensional intelligent supplementary light system and method. Background technique [0002] The panoramic camera can monitor and cover the scene without blind spots. It is equipped with a fisheye lens, or a reflective mirror (such as a parabola, a hyperbolic mirror, etc.), or is composed of multiple ordinary lenses facing different directions, with a 360-degree Panoramic field of view. One panoramic camera can replace multiple ordinary surveillance cameras, achieve seamless surveillance, realize new surveillance applications, and can be used in various fields, including prisons, government agencies, banks, social security, public places, cultural places, etc. [0003] Surveillance cameras are usually equipped with fill lights to improve the clarity of the surveillance images at night or when the light is insufficient. However, if the supplementary light design is unrea...
