Reduction of visual data by a program controlled interface for computerized manipulation

Abstract

A system consisting of an industrial robot and a computer was provided with a camera of high resolution. The camera/computer interface was provided with an electronic window which was made controllable by computer program. A rough raster scan was used for detection of presence and approximate location of the objects. A finer raster and a set of seven thresholds for the brightness were then applied in a limited window around each object only, in order to save memory space and time without losing accuracy. Thus, e.g. two objects could be detected at the location of an originally unified area, or objects of the same form but differing colors were distinguished. The observation, indentification and classification of the objects by the robot were performed as a fully automatic sequence.
