Abstract :
Due to advancement of technology and application of information technology, now we are able to measure visibility using a digital image processing method. The previous related technologies are mainly based on high-frequency information. For example, high-pass filters are used to measure meteorological visibility. This study used a simulated city landscape similar to an actual one, trying to explore the influences of different parameters of a high-pass filter on the measurement of the visibility index values. The results of the experiments showed that the simulated environment we used was effective. In the future, we will conduct more experiments to test more simulated environments and visibility measurement methods.
