This research is a preliminary project to fuse GPS and machine vision in order to improve positioning accuracy. A machine vision system has been developed to detect the movement in a tractor. The system, which consisted of a camera focused on the ground and software which processes the images, was probed in three kinds of fields. At the same time, GPS positions were being taken. The results of tests have shown that the trajectories detected by means of the vision system match with the path detected using GPS. This research is an example in which GPS and machine vision can work together.

Key words: machine vision, movement detection, block matching, GPS, trajectory, tractor, fields
