摘要

This paper proposes a new method of detecting traffic volume of intersections from aerial video processing by software, and made a simple example. First, we use aeromodelling to get traffic flow video of target area. Then, we process the video with software we developed independently, to access data we need. The software developed on the platform of MFC and OPECV based on the C++ program. We used the mixed Gauss background difference method to identify vehicles in a single frame, and the L-K algorithm and corner detection algorithm to track vehicles in the continuous video. By this way, we extract trajectories of vehicles, and then get the speed and acceleration according to the relationship between time and displacement. On this basis, we propose a method of intersection traffic volume statistics. Proved by the experiment, the data gathered from the aerial video by our software is very accurate, and the error of intersection traffic volume is within 2%. It meets the requirements of the traffic survey well. The foreground of the software is considerable.
