Title    Design of Logistics Tracking System Based on Multi-Camera                                                             

Abstract With the continuous development of computer techniques, video tracking is becoming a hotspot. In this field, object tracking based on multi-camera catch eyes of increasing researchers due to its advantages. The topic involves two main problems: 1)how to realize the object tracking based on a single camera; 2)how to connect one camera with another to keep on tracking.

The principles of object detection and tracking are introduced first in this paper. Then I elaborate a scheme, which combines algorithm of Mean Shift with Kalman filters, that can achieve real-time object tracking with a single camera.In the next sections, there are discussions on multi-camera tracking system, including its structure and the synchronization. This paper also focuses on the effective connections between different cameras. After explaining the relevant principles, I provide a scheme on the base of SURF feature in order to solve the problem of object handoff. At last, the design of object tracking system based on dual-camera is given with corresponding experiment results.

Keywords  object detection and tracking, Mean Shift, Kalman Filters, Multi-camera tracking, object handoff, SURF feature matching
