    • The invention relates to a method for the estimation of the dynamic state of a real-world object over time using a camera system, 2D image information and a combination of different measurements of the object's distance from the camera. The 2D image information is used to track an object's 2D position as well as its 2D size and 2D size change using its appearance. In addition, an object's distance from the camera is gained from one or several direct depth measurements. The 2D position and size, and the object's depth are coupled with each other to get an improved estimation of an object's 3D position and 3D velocity, and so get an improved real-world object tracking system, which can be used on a moving platform like a robot or a car with mounted cameras for a dynamic visual scene analysis.
    • 本发明涉及一种用于使用相机系统估计真实世界对象的动态状态的方法,2D图像信息以及物体与照相机的距离的不同测量的组合。 2D图像信息用于使用其外观来跟踪对象的2D位置以及其2D尺寸和2D尺寸变化。 此外,物体与摄像机的距离是从一个或几个直接深度测量获得的。 2D位置和尺寸以及对象的深度相互耦合,以便对对象的3D位置和3D速度进行改进的估计,从而获得改进的现实世界对象跟踪系统,可以在移动平台上使用 机器人或具有安装摄像机的汽车,用于动态视觉场景分析。
