摘要： A relative pose between two cameras is determined by using input data obtained from the motion of subjects, such as pedestrians, between the fields of view of two cameras, determining trajectory information for the subjects, and computing homographies relating lines obtained from trajectories in the first image data to lines obtained from the trajectories in the second image data. The two fields of view need not overlap.
摘要翻译：通过使用从两个摄像机的视野之间的对象（诸如行人）的运动获得的输入数据，确定主体的轨迹信息，以及计算从第一个轨迹中的轨迹获得的相关线的计算相似度来确定两个摄像机之间的相对姿态将图像数据提供给从第二图像数据中的轨迹获得的线。这两个视野不需要重叠。

摘要： Techniques are described to characterize motion patterns of a group of agents engaging in an activity. An analysis system receives input data associated with spatial and temporal information of at least one element of interest associated with the activity, where the object of interest may be a ball, person, animal or any other object in motion. The analysis system partitions the input data into a plurality of spatiotemporal segments and generates one or more representations of one or more sets of segments of the plurality of spatiotemporal segments based on one or more criteria. The analysis system computes a metric, such as an entropy value, for each of the one or more representations. Partial tracing data, such as ball movements in a sporting event, may be created using an inexpensive input device, such as a tablet computer, making the disclosed techniques available for a wide range of events and activities.
摘要翻译：描述技术来描述参与活动的一组代理的运动模式。分析系统接收与与活动相关联的至少一个感兴趣元素的空间和时间信息相关联的输入数据，其中感兴趣对象可以是球，人，动物或运动中的任何其他对象。分析系统将输入数据划分成多个时空分段，并且基于一个或多个标准生成多个时空分段中的一组或多组分段的一个或多个表示。分析系统针对一个或多个表示中的每一个计算度量，例如熵值。可以使用廉价的输入设备（例如平板计算机）来创建部分跟踪数据，例如体育赛事中的球运动，使得所公开的技术可用于广泛的事件和活动。
