Two Approaches To Colour Recognition In Robotics Based On A Reflectance Spectrum Analysis Method

In the recognition of colours in robotics two types of tasks can be distinguished: the task of recognition of coloured objects from an a priori known group of objects and the more universal task in which any coloured object can be recognized without any a priori information. At the beginning of the paper a review of different methods of colour recognition applied in robotics is given and all methods are classified according to one of the two above-mentioned tasks. Then the method of recognition of colours based on a reflectance spectrum analysis method is described. Using this method two approaches to colour recognition for the realization of both tasks is explained. For each task a specially designed sensor system used for the practical realization of recognition is described.
