MULTI-VIEW IMAGE MONITORING SYSTEM CAPABLE OF PERFORMING MOVING OBJECT AUTO-TRACKING PTZ CONTROL AND ACQUIRING PRECISE IMAGE

摘要

The present invention relates to a multi-view image monitoring system capable of performing moving object auto-tracking PTZ control and acquiring a precise image, which has the purpose of acquiring a PTZ image and tracking an object through elaborate tilting pan control. The present invention, if applied with respect to all feature points, can acquire PTZ control parameters (c1, c2, c3, , cN) corresponding to feature points (p1, p2, p3, , pN), respectively. A control parameter (ct), in case of a new coordinate (pt) of a detection camera, can be calculated by obtaining surrounding three points (pa, pb, pc) through a triangulating method and then, executing a linear interpolation method using a ratio of distances to each of the points with respect to the control parameters (ca, cb, cc) corresponding to the three points as in the figure (b). The present invention, if the PTZ camera moves according to the obtained control parameter (ct), can control the moving object detected in the coordinate (pt) of the detection camera to be positioned to the center of the PTZ camera, and can perform precise tilting and pan control.;COPYRIGHT KIPO 2020
