摘要： It is provided a method for conveying data on a flying object in a scene. The method including capturing video frames of the scene by video cameras to get video frames which include image of the object, identifying the object in captured video frames to get associated object parameters, calculating motion variables, solving motion equations for anticipated object trajectory taking into account certain effects, and conveying data to displaying devices. The certain effects are an effect of object collision with a ground surface, air friction, wind effect, and interaction of a spinning object with air. The method may be applied to a ball in a sporting playing field. The cameras may have variable operating parameters desirable for the calculating the motion variables, which may be determined by camera calibration using captured artifacts of the scene. Shadow of the object may be captured as well and be used to provide data absent due to occluding a of the object from a video camera. Also, the captured frames of a ball may be used to calculate parameters relating to a bat which hits the ball.
摘要翻译：提供了一种用于在场景中的飞行物体上传送数据的方法。该方法包括通过摄像机拍摄场景的视频帧以获得包括对象的图像的视频帧，识别捕获的视频帧中的对象以获得相关联的对象参数，计算运动变量，考虑到预期对象轨迹的运动方程式某些效果，并将数据传送到显示设备。某些效果是物体与地面碰撞，空气摩擦，风力影响以及纺丝物体与空气的相互作用的影响。该方法可以应用于运动场中的球。相机可以具有用于计算运动变量所需的可变运行参数，运动变量可以通过使用所捕获的场景的伪影的相机校准来确定。也可以捕获对象的阴影并且用于提供由于从摄像机遮挡对象而不存在的数据。此外，可以使用球的捕获帧来计算与击球的蝙蝠有关的参数。
