Abstract:
1. A moving object monitoring system utilizing a plurality of monitors to monitor a region, wherein each monitor works within a range of angle of monitoring and a range of overlapping angle of monitoring defined the doubly viewed region made possible with a pair of monitors, which automatically monitors a moving object by controlling said plurality of monitors, comprises: a memory module for recording a plurality of serial images of said moving object taken by said monitor and recording a plurality of to be monitored target patterns for comparing during automatic monitoring; a target identification module for analyzing said plurality of serial images and generating a plurality of target patterns, which outputs a command of target monitoring whenever said plurality of target patterns match one of said plurality of to-be-monitored target patterns; a speed calculation unit for calculating the speed at which said target object moves and converting said speed into an angular speed at which said monitor has to rotate while monitoring the target object; an angle adjustment unit which adjusts the monitoring angles of said monitor according to said angular speed to send out an angle adjustment signal; a switch unit for switching a monitoring status selected from a single-monitor monitoring status and a two-monitor monitoring status; a control unit, which retrieves said plurality of serial images stored in said memory module and sends them to said speed calculation unit for the calculation of said angular speed after receiving said command of target monitoring and receives said angle adjustment signal and sends to said monitor which is monitoring the target, and controls said switch unit to change the monitoring status; and a connection unit for connecting said memory unit, said target identification module, said speed calculation unit, said angle adjustment unit, said switch unit and said control unit.
