Abstract: At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn.

Abstract: At least one geometric characteristic for each of a number of pieces of lumber is determined. Each of the pieces of lumber may then be logically associated with at least one of a log or a cant from which the piece of lumber was sawn. The geometric characteristic may be captured by one or more scanners, for example one or more laser scanners. The geometric characteristic may, for example be a measurement of thicknesses, widths and/or wane dimensions.

Abstract: The laser enclosure includes an enclosure body which is adapted to accommodate a laser scanner therein. The enclosure with the laser assembly is used in a sawmill environment. The enclosure body includes an assembly for moving the mounted enclosure body to obtain and maintain a desired orientation and aiming for the laser scanner relative to a companion laser scanner. A movable front plate/door comprises one part of the enclosure body, mounted and arranged to be movable to an open position, permitting access to the interior of the enclosure body. The movable door also includes openings for the laser scanner components.

Abstract: The enclosure assembly includes an enclosure body which is adapted to accommodate a laser scanner therein for use in a sawmill environment. The enclosure body includes a lid portion which is hinged to permit access to the interior of the enclosure for convenient removal and cleaning of the laser scanner. A front end assembly extends from a forward end of the enclosure body and includes an air knife member mounted therein which in operation produces an air curtain which extends from the air knife towards the workpiece, tending to maintain the debris away from the laser.

Abstract: A light source is used to illuminate a sawn portion of a piece of wood and exposed surfaces of the saw blade on both sides of the sawn portion. The sawn portion and the exposed surfaces of the saw blade are then imaged substantially concurrently using a single image generator. At least one geometric characteristic of the sawn portion and at least one geometric characteristic of the saw blade are determined based on the imaging.

Abstract: The geometric characteristics for a plurality of boards that have been completely sawn by a gangsaw are determined. A sawn surface of one of the plurality of boards is then logically associated with one of the plurality of saw blades in the gangsaw.

Abstract: The method for calibration of a single point laser system used in a measuring system for wood boards in a sawmill includes the steps of storing two orthogonal dimensions of a calibration bar, the values of the two dimensions being different from each other; placing the calibration bar within the scan zone of the measuring system, which is between two opposing lasers; measuring the distance to the calibration bar from each laser in a first dimension, and rotating the bar to its orthogonal dimension and again measuring the distance to the bar from each of the lasers. The distance information to the calibration bar and the known dimensional values of the bar in the two dimensions are then used to determine that a calibration bar is present rather than a wood board to be measured. If the presence of a calibration bar is confirmed, then the distance values and the dimension values are used to determine the actual distance between the two lasers.
