Abstract
This work deals with simple and low-cost IR-sensor systems for autonomous systems. Specifically, a circular array of IR-photodiodes is investigated in the context of object recognition, localisation and differentiation. Such sensors are usually only used for the detection of objects in the near field of the system in order to avoid obstacles. However, under certain conditions, the information provided by circular IR-sensor arrays can be used to determine the angle, distance and brightness of an object. Besides a theoretical analysis of the minimal requirements for determining the number of objects and their parameters, noisy sensor readings are investigated concerning maximum possible preciseness of the estimation of the object’s distance. Finally, an algorithm that allows the determination of the distance and angle of an object, independent of knowledge of its brightness, is presented.
