Daytime Visibility Measurement with Camera during Spring in Qingdao

Abstract:

Based on digital camera method, there was using an improved dual-target method to measure atmospheric visibility. Using a digital camera to obtain images selected targets under different weather, to brightness contrast method and dual-target method were used to edge detection and Hough transform to obtain the image of the target and background, then respectively through the brightness contrast method and dual target method to calculate visibility value, in view of the different weather will dual target method and brightness contrast method and meteorological bureau issued the visibility value contrast experiment. Comparison results show that the digital camera method for visibility value and weather bureau data released by the trend is almost the same, especially dual target method. Digital camera method proved the effectiveness of Qingdao area visibility observation.
