    • It is an object of the present invention to provide a monitoring system that captures and inputs video images of a crowd with a surveillance camera for detecting normal and/or various abnormal states. The monitoring system (MS) comprises: a video image input means (1) that captures and inputs the video images of the crowd; an optical-flow calculating means (2) that calculates optical flows from the video images captured at different times; a judgment-block setting means (3) that sets judgment blocks on a surveillance area of each video image, each judgment block serving as a unit to be judged about an abnormality; an optical-flow attribute counting means (4) that counts an attribute of optical flows generated in each judgment block; a normality-evaluating-index calculating means (5) that calculates, from the counted attribute of the optical flows, an evaluation value of a normality-evaluating index for evaluating a normality of the judgment block; an abnormal-state judging means (6) that judges, from the evaluation value of the normality-evaluating index, the abnormal state of the judgment block; and an output means (7) that outputs a result of the judgment made by the abnormal-state judging means onto the video image.

    • A technique for detecting an abnormal behavior by monitoring moving objects such as human being and a car. The place where the abnormal behavior of the moving objects occurs is deduced from the position of the moving object and the direction in which the moving object moves and presented to the car. An abnormal detector comprises means for determining the position of the moving object and the direction in which the moving object moves, means for determining the place where an abnormal incident causing an abnormal behavior of the moving object occurs on the basis of the determined position and direction, and means for displaying the place where the abnormal incident occurs. Therefore it is possible to immediately know the cause of the abnormal behavior of the moving object from the video information collected by observation monitoring moving objects such as a human being and a car.
    • 一种用于通过监视诸如人和汽车的移动物体来检测异常行为的技术。 发生移动物体的异常行为的地方是从运动物体的位置和运动物体移动并呈现给汽车的方向推导出来的。 异常检测器包括用于确定移动物体的位置和运动物体移动方向的装置,用于根据确定的位置和方向确定引起运动物体的异常行为的异常事件发生的地方的装置 以及用于显示发生异常事件的地方的装置。 因此,可以从通过观察监视诸如人和汽车的移动物体收集的视频信息中立即知道移动物体的异常行为的原因。
