ABSTRACT:
A first linear sensor tracks the movement of an object through an inspection station and a second linear sensor views the object transverse to the object path to acquire a line image of the object, and a synchronizing arrangement responds to the sensed position of the object to trigger the second sensor at spaced object positions to obtain a plurality of line images which cummulatively represent the object image. The image is compared, line-by-line, as acquired with a stored model of the object to determine the correlation between the object and the model.
