Abstract

The purpose of this project is to prove that a real-time object-tracking camera can be implemented using the Digilent NEXYS board with Xilinx Platform Studio. With great ambition I set to implement the camera with RGB color tracking of bright green objects. This would make segmentation between the object of interest and its background much easier, allowing less stringent requirements on the background color beyond the object. Because of time restraints, the actual implementation remains as 8-bit grayscale, where the object of interest is intended to be white and highly contrasted from its black background. A simple algorithm is used to track the object by computing the centroid of all ‘white’ pixels in the field of view and adjusting the focal point of the camera accordingly. The rotation and tilt of the camera are modified via pulse-width modulation to two separate miniature servos controlling each axis.
