摘要
为了在车载RGB-LED颜色一致性校准算法中减少时间成本,并能更便捷地分析数据,开发了一种基于模块化的颜色参数校准实验系统。该系统面向汽车电子应用,结合伺服电动机、光电探头和颜色分析仪,通过LIN总线并使用PWM调光方法驱动RGB点亮;分析了RGB-LED混光原理和电流对RGB-LED亮度的影响;展示了校准后各种颜色的CIE坐标图以及校准时间图。经RGB-LED颜色标定实验测试,实现了RGB-LED的高精度颜色校准并具有较快的校准速度,同时实现了数据的采集和数据源的可追溯功能。
In order to reduce the time cost consumed by repetitive work and to analyze the data more conveniently during the research of color consistency calibration algorithm for RGB-LEDs,a color parameter calibration experimental system based on modular design is developed.The system combines a servo motor,a photoelectric probe and a color analyzer to drive RGB lighting through LIN bus communication and PWM dimming method.The results of RGB-LED color calibration experimental test show that the RGB-LED can be calibrated with high accuracy and fast calibration speed,and the data acquisition and data source traceability can be achieved.
