基于视频的智能交通信息检测算法的研究

Study of an Algorithm in Intelligent Traffic-information Detection Based on Video Technique

该文通过自适应混合高斯模型在一系列连续视频图像中提取出背景并进行更新的基础上,利用背景差法对视频图像中的运动车辆进行检测并进行占道比计算,以实现对高速公路上过往车辆的自动监控功能。实验结果表明,该系统能够快速地适应环境的变化,达到实时的要求,具有较好的效果。

In the paper, an adaptive mixture Gaussian model is used as the background model, the background is extracted from the video images. In order to automatically monitor the passing vehicles on the highway＇, a method of background subtraction is applied to detect the moving vehicles and finally the ratio of vehicle - occupied was computed. Experimental results show that the system can fast adapt the environmental changes, meet the real - time re- quirements and have a good effect.
