“Tracking of Moving Object Employing CoordinateDifference Algorithm on sbRIO Chip”

Abstract

In this paper, object tracking system using Co-ordinate difference algorithm and template matching is described. It is designed on sbRIO chip which includes both Field Programmable Gate Array (FPGA) and DSP. sbRIO can process 176x144 resolution video sequences and provide the location of a predefined object in real time using LabVIEW 12.0 vision and motion software. The conceptsof pattern matching and co- ordinate differencing algorithm make it simple and efficient. Logitech c110 camera has been used to grab the video frames and track an object. Pattern matching is used to match the template and find the co-ordinate value of the object in the image. Once the co-ordinate value of the object has been detected, it is tracked by the camera. To automate the tracking process, the camera is mounted on a pan-tilt arrangement with a stepper motor, which is synchronized with a co-ordinate difference algorithm. As and when the object being tracked moves out of the certain pixel range of the camera, the pan-tilt setup is automatically adjusted to move the camera so as to keep the object in view. Such a tracking system is used in automated video conferencing system and also has application as a surveillance tool.
