背景技术Background Art
边境区域通常具有较长边界线，为了对边境区域进行监控，通常会在边境区域的边界线间隔设置若干哨站，工作人员通过在哨站上对边境区域进行目视观察，从而对边境区域进行实时监控，确定是否有人非法闯入边境区域。上述方式虽然能够对边境区域进行近距离的检测，但是工作人员的目视观察模式在观察范围和观察实时性上存在一定的局限性，同时还需要安排大量工作人员对边境区域沿线进行长时间的监控，降低边境监控的全面性和可靠性。Border areas usually have long border lines. In order to monitor border areas, several sentry posts are usually set up at intervals along the border lines of border areas. Staff members visually observe the border areas from the sentry posts, thereby monitoring the border areas in real time to determine whether anyone has illegally entered the border areas. Although the above method can detect border areas at close range, the visual observation mode of staff members has certain limitations in terms of observation range and real-time observation. At the same time, a large number of staff members need to be arranged to monitor the border areas for a long time, which reduces the comprehensiveness and reliability of border monitoring.

By extracting the corresponding picture frames from the video stream data in the border area and forming a picture frame queue, the computational workload of the video stream data can be reduced. At the same time, iron mesh fences and the like are set up in the border area as border boundary markers. From each picture frame, the personnel and border boundary markers on the screen and the relative position relationship between the two can be identified. The border boundary markers can be used as a reference to determine whether an illegal intrusion event has occurred; for example, when a person crosses the border boundary marker, it can be determined that an illegal intrusion event has occurred.
