    • A solution for monitoring an area includes using a region schema for the area. The region schema can include a set of prototypical tracks, each of which includes a start location, an end location, and a trajectory. The trajectory comprises an expected path an object will travel between the start location and the end location and can include variation information that defines an amount that an object can vary from the trajectory. The region schema can be generated by obtaining training object tracking data for the area for an initialization time period and evaluating the object tracking data to identify the set of prototypical tracks. While monitoring the area, monitored object tracking data is obtained for a monitored object in the area, and abnormal behavior of the monitored object is identified when the monitored object tracking data for the monitored object does not follow at least one of the set of prototypical tracks in the region schema.
    • 用于监视区域的解决方案包括为区域使用区域模式。 区域模式可以包括一组原型轨道,每个轨道包括起始位置,终点位置和轨迹。 轨迹包括对象将在起始位置和结束位置之间行进的预期路径,并且可以包括定义对象可以从轨迹变化的量的变化信息。 可以通过获取用于初始化时间段的区域的训练对象跟踪数据并且评估对象跟踪数据来识别该组原型轨迹来生成区域模式。 在监视该区域时,为该区域中被监视对象获得被监视对象跟踪数据,并且当监视对象的被监视对象跟踪数据不遵循该组原型轨道中的至少一个时,监视对象的异常行为被识别 在区域模式。
