A Network Video Device Based on Specific Target Tracking

Recognizing a specific moving target and capturing image with its trajectory has a wide range of applications. This paper introduces an embedded network video device system scheme which is used for target tracking and it is based on FPAG, ARM and Embedded Linux OS. The embedded network device consists of three main parts: image acquisition, image transmission, image processing included image recognition and target tracking. Image acquisition is implemented by the digital image sensor MT9M032 controlled by FPAG. Image processing and image transmission are implemented by ARM which is the core part of the whole system. By calculating the relative centroid coordinates of the two adjacent target images, the system can control the deflection of the camera lens and capture a moving object image with its trajectory. Meanwhile, the target image data can be transmitted to the computer through the Ethernet. A system composed of the network video device can achieve searching the target by comparing with the given target feature. And it can be used for video surveillance and industrial control.
