Abstract

The embodiment of the invention discloses an RGB-LEDs atmosphere lamp calibration method and device. The method comprises the following steps: controlling the lightening of an atmosphere lamp and collecting the color data of the atmosphere lamp, wherein the color data comprises the duty ratio of RGB (Red, Green, Blue), the color coordinate of a lamp holder and the brightness; the acquired color data are analyzed and calculated, and the RGB values of the color coordinates are calibrated according to a preset calibration rule; sending the calibration data to the lamp holder to complete color calibration; according to the embodiment of the invention, automatic calibration is realized, the calculation efficiency is high, and the expansibility is high.

Description

technical field [0001] The embodiments of the present application relate to the technical field of color calibration of automotive ambient lights, and in particular, to a method and device for calibrating RGB-LEDs ambient lights. Background technique [0002] With the continuous development of automotive electronics, the application of automotive ambient lights is becoming more and more extensive, but due to factors such as the material and service life of the ambient lights, there will be color differences in the process of using the same set of primary color ratios to light up colors, resulting in The color coordinates are not uniform. [0003] With the continuous popularization of vehicle ambient lights, various car manufacturers have continuously improved the requirements for the consistency of colors when the ambient lights are lit. Taking Volkswagen as an example, the ambient lights will be tested for 30 colors when they leave the factory, and the color deviation value...
