    • Methods and apparatus for determining a trajectory of a axisymmetric object in 3-D physical space using a digital camera which records 2-D image data are described. In particular, based upon i) a characteristic length of the axisymmetric object, ii) a physical position of the camera determined from sensors associated with the camera (e.g., accelerometers) and iii) captured 2-D digital images from the camera including a time at which each image is generated relative to one another, a position, a velocity vector and an acceleration vector can be determined in three dimensional physical space for axisymmetric object objects as a function of time. In one embodiment, the method and apparatus can be applied to determine the trajectories of objects in games which utilize axisymmetric object objects, such as basketball, baseball, bowling, golf, soccer, rugby or football.
    • 描述了使用记录2-D图像数据的数字照相机确定3-D物理空间中的轴对称物体的轨迹的方法和装置。 特别地,基于i)轴对称对象的特征长度,ii)从与相机相关联的传感器(例如,加速度计)确定的相机的物理位置,以及iii)从相机捕获的2-D数字图像,包括时间 每个图像相对于彼此生成的位置,速度矢量和加速度矢量可以作为时间的函数在轴对称对象对象的三维物理空间中被确定。 在一个实施例中,可以应用该方法和装置来确定使用诸如篮球,棒球,保龄球,高尔夫,足球,橄榄球或足球之类的轴对称物体的游戏中的物体的轨迹。

    • A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and/or one or more observers in the area. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and/or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner
    • 所公开的设备提供轨迹检测和反馈系统。 该系统能够检测自由飞行中的一个或多个移动物体,分析每个对象的轨迹并且向已经将对象发射到飞行中的人提供即时反馈信息,和/或该区域中的一个或多个观察者。 在特定实施例中,可以使用远程检测移动物体的轨迹的非侵入式机器视觉系统来评估玩家在篮球场的篮球射击的轨迹参数。 可以使用声音投影装置以听觉格式将反馈信息(例如,进入篮球圈的轨迹入射角和/或入射到环中的进入速度)输出到玩家。 该系统可以可操作地被设置并以基本上自主的方式操作
