Title:
METHOD AND SYSTEM FOR CONTROLLING COLOR TEMPERATURE OF STAGE LAMP, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/052184
Kind Code:
A1
Abstract:
A method and system for controlling the color temperature of a stage lamp, and a computer device and a storage medium. The method comprises: acquiring the color coordinates and illuminance of each single-color lamp, and obtaining, according to an illuminance ratio of the illuminance to a color temperature, initial illuminance data of the single-color lamp at the current color temperature (S101); calculating a coordinate difference between mixed color coordinates, which are obtained by means of performing illuminance mixing on the initial illumination data, and target color coordinates (S102); when the coordinate difference is within a first difference range, calculating the illuminance variations of R and B according to the mixed color coordinates, the target color coordinates, R correction coordinates and B correction coordinates (S103); and obtaining the latest channel values of R and B by means of the illuminance variations of R and B, and according to the latest channel values, regulating and controlling the color temperature of each single-color lamp for color mixing (S104). By means of the method, the problem of the same color temperature of different lamps being different due to color temperature drift and color rendering index reduction caused by the differences between lamp beads of different lamps is solved, and actual application requirements are satisfied.
