摘要利用CCD成像基本原理,在研究了道路照明亮度与图像关系的基础上,设计了一种基于CCD数码相机的道路照明亮度测试系统,并设计了一种道路照明的实用标定装置。借助于MATLAB软件给出了数码图片的像素灰度值与亮度之间的数学模型,对标定环境中关键影响因素进行了定量研究,并在盐城市松江路进行实测,测试结果与参照值的相对误差均在15%以内,表明新设计的测量方法有效地提高了道路照明指标测试的精度与效率,减少了测量误差。

Abstract：Based on the imaging property of CCD, a method for design of CCD imaging luminance for road luminance test was proposed. It is analyzing the relationship between the gray-level of the image pixel and the luminance of the measurement point and find a road lighting practical demarcation installment. To improve the measurement accuracy, the influential factors of the calibration environment in a quantitative study is analyzed. With the aid of the MATLAB software between the digital picture element grey level and brightness mathematical model is given , the Songjiang Road in Yancheng city is measured. The relative error of the test results and the reference value is within 15% indicting that the new designed method is effective to improve the road lighting test accuracy and reduce the measuring error.
