Problems solved by technology

Infrared microwave probes have the advantages of non-contact detection and high reliability, but their disadvantages are mainly the limited detection range, which leads to excessive use of probes in engineering, complicated wiring and increased costs, and cannot be applied to rooms whose height exceeds the detection distance of the probe.

Embodiment Construction

[0014] refer to figure 1 As shown, a lighting control method based on human body detection of the present invention, its working principle is: an ordinary camera installed vertically or obliquely downward takes images of lighting places that require intelligent lighting control, and the captured The image signal is sent to the control computer; it is judged by the control computer whether there is a person, if there is a person, it will send a control signal to the lighting regulator to turn on the lighting fixture to the set illuminance; when the person leaves, it will send a control signal to the lighting regulator, Turn off lighting fixtures. Specifically include the following steps:

[0015] (1) Install a CCD or CMOS camera in the lighting place that requires intelligent lighting control, connect the output signal of the camera to the control computer, and set the appropriate illuminance in the control computer according to the needs of different areas of the lighting pla...

Abstract

The invention discloses an illumination control method based on human body detection, which is characterized by comprising the following steps of: (1) installing a CCD (Charge Coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor Transistor) camera and connecting to a control computer, and setting required illumination intensity in the control computer; (2) detecting a manned area through a probabilistic background model; (3) converting a current frame image from an RGB (Red, Green, Blue) color space into an HSV (Hue, Saturation, Value) color space by a system when someone appears at some area in the illumination occasion so as to obtain the image brightness of the current frame, and automatically controlling the brightness of an illumination device at the area by combining the illumination intensity value obtained by an illumination intensity sensor; and (4) automatically closing the illumination device at the area by the system when detecting that someone leaves the area. The invention can detect the human body in long distance and large scale, enhances the intelligence of an illumination control system, has the advantage of lower cost and is used for intelligently controlling lamplight at the illumination occasions.

Description

technical field [0001] The present invention relates to a lighting control technology, more specifically, it relates to a lighting control method based on human body detection. Background technique [0002] Illumination is a method of providing light sources for the human body's visual receptors. Therefore, the core task of an intelligent lighting system is to detect the position of the human body and properly illuminate a certain range centered on the human body. In the current intelligent lighting system, the equipment used to detect the position of the human body is mainly an infrared microwave probe. Infrared microwave probes have the advantages of non-contact detection and high reliability, but their disadvantages are mainly the limited detection range, which leads to excessive use of probes in engineering, complicated wiring and increased costs, and cannot be applied to rooms whose height exceeds the detection distance of the probe. .
