IRRIS - An image registration, recognition, and inspection system

This paper briefly describes IRRIS-100^TM, a machine vision system shown in operation at four recent exhibitions sponsored by the Society for Manufacturing Engineers. A gray level vision system combining Artificial Intelligence methods with statistical and structural pattern recognition techniques, IRRIS-100^TMcan rapidly determine the location and orientation of touching and overlapping objects that are randomly positioned within the camera´s field of view, without special lighting, and without having to find connected components in the image. With the gray level image registered in a standard orientation in memory, customized algorithms can examine specific details in the image. Based on a Motorola 68000 processor, the system communicates location and orientation coordinates and other information for pick and place, de-palletizing, assembly, recognition, and inspection applications, over two RS232 ports and one 16 bit parallel port.
