摘要

An automatic digital photography visibility system(DPVS)is presented, which can di- rectly measure and monitor horizontal visibility during daytime through digital shooting. After shooting a scene of given black object and background via its CCD digital camera, the system can capture and transfer photographic images in the camera to a computer, as well as process the digital images and calculate the value of visibility. The formulas for calculating visibility with this method and analysing the effect of non-black object on measured results have also been de- rived.
