Abstract

The invention relates to a double-camera automatic coordination multi-target eagle eye observation system and an observation method thereof. The system comprises a hardware platform, a wide angle camera, a pan / tilt / zoom (PTZ) camera, a processor and a multi-channel video acquisition card. The observation method comprises the following steps of: calibrating two cameras to obtain an angle that a moving camera rotates and aligns with any position of the wide angle camera; detecting moving targets from the wide angel camera, and tracking and marking; selecting a target; controlling the PTZ camerato zoom and track if the target moves fast; amplifying the target if the target moves slowly; positioning interested characteristics; and secondarily amplifying and observing an interested region. The system has the advantages of low cost, simple implementation and the like, and can be widely applied to multi-target video tracking fields such as robots, intelligent transportation, video monitoring and the like.

Description

technical field [0001] The present invention relates to video surveillance, in particular to a dual-camera automatic cooperative multi-target eagle-eye observation system and its observation method. The method is a method for obtaining clear details of a designated target while obtaining large-scale scene information through automatic cooperative control of dual cameras . Background technique [0002] The disadvantage of traditional video surveillance is that when the target is far away from the camera and is constantly moving, clear images of the target of interest in a wide range of scenes cannot be obtained only by changing the focal length; the multi-camera video surveillance system is complex in structure and high in cost. Invention patent 200410016455.9 uses multiple cameras for video surveillance, and uses one panoramic camera and multiple tracking cameras to obtain global information and detailed information of abnormal targets. Its realization technology relies on m...
