| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 96 === In order to capture a high resolution view of interested target region, we implement a dual camera tracking system that has two stages. In the first stage, the input to a target tracking subsystem is video streams from a single web camera. The subsystem analyzes the video content by extracting the foreground from the background, detecting and tracking the objects. The foreground is separated from the background by using background learning, change detection, change classification and foreground object segmentation methods. The objects are detected and tracked by using contouring and blobs tracking techniques. In the second stage, coordinate transformation subsystem transforms the coordinate of object on webcam coordinate system to PTZ coordinate system by using planar homography mapping method. In order to capture a high resolution view of interested target region from PTZ, the coordinate transformation subsystem adjusts automatically the PTZ parameters based on the coordinate and size of the object on PTZ coordinate system.
