Analysis of Influencing Factors on Gauging Accuracy of Average Luminous Intensity for Light Emitting Diode Light Source

  • 摘要: 以LED光度光色空间分布综合校准装置中平均发光强度的测量为对象展开研究。为提高检测精度,通过在远/近场条件下测量距离和LED安装角度偏差对平均发光强度影响的分析,对检测系统中距离、定位实现装置提出精度要求。系统中采用满足精度要求的位移台实现远/近场距离调节;以CCD采集LED轮廓图像,使用Hough变换和图像质心结合的方法对LED的安装进行准确定位,从而提高LED平均发光强度的测量精度,保证检测系统具有良好的可靠性和准确性。
