Abstract :
This paper presents a real-time algorithm for color sorting edge-glued panel parts. The algorithm consists of color class training and real-time sorting procedures. The algorithm uses 3-D histograms to characterize the surface color of a part´s face as well as a color class and employs the minimum-distance classifier to label the face. In addition to real-time sorting, a technique is used to select the better of the part´s two faces based on class priorities and color difference values for the two part faces. This algorithm has been tested in a plant, and the sorting results are satisfactory
