Abstract

The invention discloses an intelligent infrared control circuit and a control method thereof. The control circuit includes: a camera for taking pictures; a DSP processor for controlling the work of the system and partitioning the pictures taken by the camera to obtain picture areas The highest brightness and output the PWM signal whose duty ratio changes with the brightness; the infrared voltage adjustment module generates an output voltage that changes with the brightness under the control of the PWM signal output by the DSP processor; multiple infrared lamps D2-DN are connected to The output voltage is used to generate infrared light, and the invention can solve the problem of overexposure of objects caused by the infrared camera at a short distance.

Description

technical field [0001] The invention relates to the technical field of intelligent monitoring and image processing, in particular to an intelligent infrared control circuit and a control method thereof. Background technique [0002] With the continuous development of video surveillance technology, more and more infrared cameras are used in practical projects. Infrared cameras have always been used as a monitoring method at night. Infrared cameras can clearly image at night and overcome the problem of blurred images of ordinary cameras at night. Infrared cameras are used more and more in fields such as transportation, banking and public safety. [0003] Infrared camera technology is generally divided into active infrared camera technology and passive infrared camera technology. Passive infrared camera technology is a camera made of the principle that any substance has infrared radiation above absolute zero, and the higher the temperature of the substance, the more infrared r...
