Silhouette imaging for feeding and orienting parts Available to Purchase

Discusses the use of silhouette imaging in correcting the feeding and orienting of parts in assembly operations. Using sensors that can sense edge points via data transitions, edge detecting algorithms can be employed to orient parts or gauge discrimination. Outlines the advantages and disadvantages of dealing with a binary image in relation to greyscale image analysis. Examines the various sensor technologies that can be used to create an article silhouette and looks at the benefit of using a backlit CCD array system where the silhouette of a transparent or opaque article is required.
