Abstract

The invention discloses a lighting control method and system. The lighting control method comprises the following steps that an original image of a target object is obtained by an imaging device; color enhancement processing is performed on the original image to obtain a color enhancement image; color coordinate calculation is respectively performed on all pixels in the original image and the color enhancement image to obtain a first colorimetric parameter C and a second colorimetric parameter Cr; feedback control calculation is performed according to the first colorimetric parameter C and the second colorimetric parameter Cr to obtain a first drive parameter D; the first drive parameter D is sent to a lighting device, so that a first drive current value output by the lighting device is regulated by the lighting device according to the first drive parameter D; whether the first colorimetric parameter C reaches a nominal value is detected; and if the first colorimetric parameter C does not reach the nominal value, the steps are circularly performed until the first colorimetric parameter C reaches the nominal value. The effect that the lighting device is automatically regulated to enhance the color contrast of a lighted object is realized by using the lighting control method and the lighting control system.

Description

technical field [0001] The present invention relates to the field of lighting equipment, in particular to a lighting control method and system. Background technique [0002] In the existing lighting system, the dimming device usually does not have the function of calculating the control signal according to the measured illuminance or color. The lack of these measured information can be mainly attributed to the difficulty of measuring these physical quantities: a certain point can be measured with a photodiode or a phototransistor. Illumination, color, but it is quite difficult to use them to achieve multi-point measurement of the surface of the illuminated object, because a large number of such sensors are difficult to install and affect the appearance. In addition, the lack of feedback control makes the lighting system unable to ensure that the illuminance or color of the output light meets the specified requirements. In some special applications, such as operating lights,...
