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.
