Abstract

The computer process controls operation of a system which sorts objects by surface characteristics. The system includes a multi-rail conveyor, an imaging unit for each rail of the conveyor and a computer including a user interface. Each imaging unit includes at least one camera, and at least one block of LEDs of multiple predetermined colors.The process initializes system hardware and software, calibrates the imaging units, sets, tests and reports various parameters for imaging, automatically or under user control, and synchronizes the operation of the imaging units with conveyor action to produce optimal imaging, as well as controlling sorting based upon imaging output.
