【摘要】 针对低空飞行器(飞艇)为平台获取的高清晰交通视频数据,通过对交通视频序列数据进行运动补偿与配准,提出了一个在复杂变化背景下基于帧差法的运动目标(车辆)快速检测与提取方法。实验结果验证了本方法的准确与可靠性。更多还原

【Abstract】 Currently,the conflict between vehicle and road is becoming increasingly serious.How to implement advanced technology to obtain traffic information fast and accurately becomes a key point to upgrade the level of transport management and services.Access dynamic traffic information rapidly based on the low-altitude aircraft becomes an improtant expansion of conventional collection means.This paper aimes at low-altitude aircraft(airship) as a platform to obtain the high-definition video data,and proposes a method for detecting moving targets(vehicles) quickly and accurately in the complex situation.Finally,massive video data were acquired by low-altitude aircraft platform,and the results prove the proposed method is capable of detecting moving vehicles fast and reliably.更多还原
