针对复杂环境中道路背景图像的快速获取问题,提出了一种快速有效的道路背景提取和更新算法。应用改进的多帧平均算法提取背景,采用改进的Surendra算法对背景进行更新。实验结果表明,该算法能够减轻初始静止车辆对背景建立的影响,能及时消除由于初始帧中目标移动而造成的鬼影,对光线变化鲁棒性高、速度快、更新效果好。
針對複雜環境中道路揹景圖像的快速穫取問題,提齣瞭一種快速有效的道路揹景提取和更新算法。應用改進的多幀平均算法提取揹景,採用改進的Surendra算法對揹景進行更新。實驗結果錶明,該算法能夠減輕初始靜止車輛對揹景建立的影響,能及時消除由于初始幀中目標移動而造成的鬼影,對光線變化魯棒性高、速度快、更新效果好。

Aiming at the problem of fast extracting road background image in complex scenes, an effective algorithm about road background extraction and updating is presented. An improved algorithm for time averaged background images (TABI) is used to the background extraction, then an improved surendra algorithm is applied to the background updating. Experimental results show that the proposed algorithm can reduce the influence of initial static vehicle on the background extraction and eliminate in time the ghosts caused by the motion of objects in the initial frame. The proposed algorithm is robust under lighting variations,fast in speed and satisfactory in updating performance.
