Positioning and Tracking System for the Precise Control of a Quadcopter
The aim of this project was to design a system which tracks a quadcopter more accurately than GPS (+/- 2m). The operating space for tracking is 50 x 50 x 50 meters. The solution developed consists of two cameras mounted on a pan-tilt unit each to track the quad copter and determine its position using image processing. For this purpose, the two cameras are individually mounted on tripods about 2 meters above ground and 5 meters apart, and track the red ball beneath the quadcopter independently. Image processing is performed using the OpenCV library on a notebook running Windows 7. The accuracy achieved is better than +/- 0.5 meters at a distance of 75 m. Unlike GPS, the system can work indoors as well as outdoors.
