Abstract
A “Woodprint™” characterization and identification technique employs cameras (16), lighting (14), camera interface hardware (18), a computer (20), and/or image processing software to collect and analyze surface characteristics of pieces of wood (8) to track them through an automated production process in real-time with information that is specific to each wood piece (8), such as what machining is required, its value, and/or its destination. When a wood piece (8) reaches a point in the production process where a decision is required, its unique identity is used to retrieve appropriate information previously determined and assigned to the wood piece (8).
