Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control system for multi-light source illumination detection and correction. Background technique [0002] Illuminance, the unit of lux, means the luminous flux received by the unit area of ​​the surface of the subject, referred to as illuminance, 1 lux is equivalent to 1 lumen / square meter, there are various illuminance meters on the market at present, and illuminance meters are usually It is composed of a selenium photocell or a silicon photocell with a filter and a microammeter. The photocell is a photoelectric element that directly converts light energy into electrical energy. When the light hits the surface of the selenium photocell, the incident light passes through the metal film to reach the semiconductor selenium layer and On the interface of the metal film, a photoelectric effect is generated on the interface, and the magnitude of the generated ph...

Problems solved by technology

[0004] The purpose of the present invention is to provide an automatic control system for multi-light source illuminance detection and correction, to solve the problem that the existing illuminance meters proposed in the above background technology are mostly hand-held illuminance meters, which require manual operation and measurement. If the measurement angle is not accurate, The result of measuring the illuminance value will also change, the measurement error is large, the error control is difficult, and the data input feedback also requires manual input. For a dome light source composed of multiple luminous objects, the measurement accuracy is poor, the intelligence is low, and it takes a long time. It is impossible to correct the illuminance. There are some inventions about illuminance or brightness measurement and calibration, which mainly use the principle of illuminance meter to connect the terminal and automatic measurement equipment. This type of instrument can automatically measure the illuminance data of multiple light sources, and automatically Input data for analysis, but cannot dynamically track multi-position and multi-angle luminous objects, cannot accurately and quickly obtain the position of luminous objects, and cannot use the measurement results of multi-position and multi-angle luminous objects for automatic correction of the illuminance of luminous objects
