(English Abstract)
When CCTV installed at regular intervals on existing highway are used to generate real-time road hazard weather information, the driver can be provided with road situation information combined with current weather. In order to generate information such as rainfall and visibility distance from CCTV images, it is essential to analyze the data change pattern of time series images. In this paper, we propose a data analysis based weather information generation method that extracts graph patterns from one or more ROIs and generates numerical rainfall and visibility distance to generate image data patterns according to weather change. In addition, we describe a method for determining the optimal size of ROI and the interval between multiple ROIs that can optimally detect fine weather image changes due to the corrective distance and rainfall. As a result of experiments, we show the optimal ROI size and the spacing between ROIs.
