Embodiment Construction

[0018] Principle of the present invention and content are as follows:

[0019] 1. Set up multiple photoelectric sensors according to the size and layout of the stage, use the photoelectric sensors to collect the ambient light information of the stage, use the adaptive parameter solving unit, use the neural network model to solve the brightness value of the color screen, and control the brightness of the color screen in real time; , layout, etc., the light reflectivity and scattering rate caused by the difference have a negative impact on the visual effect of the stage.

[0020] 2. Collect the lighting parameters of the stage lighting controller, use the adaptive parameter solving unit, use the neural network model to solve the brightness value of the color screen, and control the brightness of the color screen in real time; eliminate the problem caused by the difference in the number and layout of the stage lights that need to be matched with the performance The negative impac...

Abstract

The invention discloses a self-adaptive control system and a method of stage screen luminance, integrating stage environment optical parameters, stage light parameters, stories and screen luminance value information of hand control to realize the self-adaptive regulation of the stage screen luminance. The stage environment optical parameters are acquired by a photoelectric sensor, the stage light parameters are obtained by a light controller, the screen luminance parameters required by the stories are read by story configuration files preset by the stage design personnel, and the screen luminance value of the hand control is input on a hand controller by the stage design personnel. The parameters are transmitted to a server, the screen luminance value is solved by adopting a neural network model, the luminance value is sent to a screen luminance controlling lower computer of an LED display screen to control the screen luminance of the LED display screen in real time.

Description

technical field [0001] The invention relates to the technical field of stage digital color screens, in particular to an adaptive control system and method for brightness of stage digital color screens. Background technique [0002] With the development of society and the advancement of science and technology, people's spiritual and cultural life has become rich and colorful. As a part of spiritual and cultural life, going to the theater to watch performances is an important way to cultivate sentiment and obtain physical and mental pleasure. As an important part of the theater stage performance, the stage background plays an important role in exaggerating the atmosphere of the scene and enhancing the stage effect. The stage background of theater performances in our country is the traditional hanging soft curtain, and the plot of each scene needs to be replaced with the hanging soft curtain. The hanging scene soft curtain can be divided into hard scene and soft scene: the ha...
