The invention relates to an arrangement for product control of a product (20, 21), during or after a production process, at a transport arrangement (10, 11) which is arranged to transport the product (20, 21) to be controlled. The arrangement comprises a first camera arrangement (31) which is arranged to take at least one image of at least a part of the product (20, 21) when the product is in or at the transport arrangement (10, 11). The arrangement also comprises a first illumination arrangement (30; 60) which is arranged to emit light for detection by the first camera arrangement (31). The arrangement also comprises a computation unit which is arranged to receive said at least one image from the first camera arrangement (31) and to determine at least one geometrical property of the product (20, 21) based on said at least one image. The invention also relates to a method, a computer program and a computer program product for controlling a product which is transported during or after the production process.

An arrangement for an inspection of plate-shaped objects moving relative to a camera device in a direction of motion through at least two observation areas. The arrangement includes the camera device which includes one single camera which comprises a matrix sensor, and an image processor. In a first detection state, a first observation area running diagonally opposite to the direction of motion is represented on a first image area of the camera device and is recorded as a strip-shaped image. In a second detection state, a second observation area is represented on a second image area of the camera device and is recorded as a strip-shaped image. The image processor merges the strip-shaped images recorded in the first detection state and in the second detection state to form two-dimensional images. All image areas are located on the matrix sensor.

A system including a gantry structure; a first and a second saw head movable along at least part of the length of the gantry structure; and a first and a second lumber support also movable along corresponding lengths of the gantry structure. A controller moves the first saw head and first lumber support adjacent a first location along a board and moves the second saw head and second lumber support adjacent a second location along a board, and operates the first and second saw heads to cut first and second ends off the board. The controller then moves the saw heads and the lumber supports relative to the board to third and fourth locations and operates the first and second saw heads to cut third and fourth end pieces off. The saw heads and lumber supports optionally move together and rotate around respective vertical axes to enable angled board cuts.

A method and system for detecting and controlling the quality of debarking at the surface of a wooden log provide information on main parameters related to the debarking quality of the log surface, including fiber loss and residual bark. The debarking quality detecting method and system involve measurement of three-dimensional profile of at least a portion of the log surface to generate corresponding profile image data, which is processed to generate data indicative of the texture of the log surface. The texture data is then analyzed to generate resulting data on the debarking quality parameters. That quality indicative information can be generated on a continuous basis to provide an objective assessment of the quality performance in real-time in view of target productivity, and may then be used to perform optimal adjustments of the debarker operating parameters, either manually by the operator or automatically through feedback control.
