BARRANCO GUTIERREZ, Alejandro Israel e MEDEL JUAREZ, José de Jesús. Artificial vision and identification for intelligent orientation using a compass. Rev.fac.ing.univ. Antioquia [online]. 2011, n.58, pp. 191-198. ISSN 0120-6230.
A method to determine the orientation of an object relative to Magnetic North using computer vision and identification techniques, by hand compass is presented. This is a necessary condition for intelligent systems with movements rather than the responses of GPS, which only locate objects within a region. Commonly, intelligent systems have vision tools and identification techniques that show their position on the hand compass without relying on a satellite network or external objects that indicate their location. The method of intelligent guidance is based on image recognition for the red needle of a compass, filtering the resulting image, and obtaining the angle direction, that allows finding the orientation of the object.
