A system and method for aerial video traffic analysis are disclosed. A particular embodiment is configured to: approximate a vehicle's region; receive a region map from a database, wherein the regionmap corresponds to the vehicle's approximated region and comprises a plurality of region points indicating an expected roadway lane; receive a response image generated by an imaging device, the response image comprising information relating to the vehicle's environment; generate a response map from the response image, the response map comprising a plurality of response points indicating the vehicle's location; compare the response map to the region map; and predict the vehicle's location based on the differences between the response points and the region points.
公开了一种用于空中视频交通分析的系统和方法。特定实施例被配置为:近似车辆的区域;从数据库接收区域图,其中该区域图与车辆的近似区域相对应,并且包括指示预期道路车道的多个区域点;接收由成像设备所生成的响应图像,响应图像包括涉及车辆环境的信息;根据响应图像生成响应图,该响应图包括指示车辆的位置的多个响应点;比较响应图和区域图;以及基于在响应点和区域点之间的差异来预测车辆的位置。
