ABSTRACT:
A high resolution object handling system serves as an object discrimination - identification by creating an object silhouette. The objects are singulated on a conveyor and scanned by a linear array of CCD units (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter which is synchronized with the scanner. A microprocessor with a first in, first out buffer memory needs only a capacity to handle the count value rather than all data from the pixels.
