Abstract:
1. A hand-off monitoring method for monitoring a space divided into several monitoring regions, wherein each of the monitoring regions is equipped with a sensor and is monitored by a surveillance camera, comprising: one of the sensor producing a warning signal; a computer apparatus receiving the warning signal; according to the warning signal, the computer apparatus identifying a source location where the sensor producing the warning signal is located and a first surveillance camera related to the source location; according to a video signal provided by the first surveillance camera, the computer apparatus identifying an object triggering the sensor to produce the warning signal; the computer apparatus predicting a moving path of the object according to a non-linear movement prediction model, wherein the moving path comprises the object moving from a first monitoring region monitored by the first surveillance camera to a second monitoring region monitored by a second surveillance camera and from the second monitoring region to a third monitoring region monitored by a third surveillance camera; wherein the non-linear movement prediction model comprises a plurality of moving mode matrixes; wherein each of the moving mode matrixes corresponds to a single monitoring region movement and each of the moving mode matrixes is defined according to a first matrix equation as following: wherein k is natural number, P k denotes a monitoring region movement mode of the obiect while the obiect is at k-th single monitoring region movement and a i,j k denotes a movement probability of the obiect moving from a monitoring region j into a monitoring region i while the object is at k-th single monitoring region movement and n denotes numbers of the monitoring regions; and according to the moving path, the computer apparatus performing a control operation, according to the moving path, to control at least the first surveillance camera, the second surveillance camera and the third surveillance camera so as to hand-off monitor the object.
