Tracking system and method for tracking wood products in a production line
The wood tracking system for a production line generally has a wood product optimizer; a wood product trimmer downstream from the optimizer in the production line; a conveyor for moving wood products from the optimizer to the trimmer and across a handling area therebetween, the optimizer being configured to scan each of the wood products in a given order and to generate optimization data for each wood product; and a computer vision system positioned proximate the handling area along the production line, the computer vision system having a camera, a processor in communication with the optimizer and with the trimmer and a computer-readable memory for storing the optimization data, the processor being configured to acquire images of the handling area from the camera, the processor being configured to associate the optimization data of a given wood product across each of the images until it arrives at the trimmer.
1. A wood tracking system for a production line, the wood tracking system comprising:
a wood product optimizer positioned along a production line;
a wood product trimmer positioned downstream from the wood product optimizer in the production line;
a conveyor configured for moving a plurality of wood products from the wood product optimizer to the wood product trimmer and across a handling area between the wood product optimizer and the wood product trimmer, the wood product optimizer being configured to scan each of the wood products in a given order and to generate optimization data for each wood product; and
a computer vision system positioned proximate the handling area along the production line, the computer vision system having a camera, a processor in communication with the wood product optimizer and with the wood product trimmer and a non-transitory computer-readable memory for storing the optimization data, the processor being configured to acquire at least two images from the camera and representing the handling area at, at least two different moments in time, the processor being configured to associate the optimization data of a given wood product represented in a first one of the at least two images to a corresponding wood product represented in a second one of the at least two images until the given wood product arrives at the trimmer;
the non-transitory computer-readable memory having stored thereon instructions that, when executed by the processor, perform the steps of:
determining position and orientation data associated to each wood product represented in each of the at least two images; and
associating the optimization data of each wood product represented in the first image to a respective wood product represented in the second image based on the position and orientation data determined in the first and second images.
2. The wood tracking system of claim 1 further comprising a lighting system in communication with the processor to control a lighting environment of the handling area.
3. The wood tracking system of claim 1 wherein the camera includes more than one cameras each having a corresponding field of view associated to a given sub portion of the handling area.
4. The wood tracking system of claim 1 wherein the camera has a frame rate of at least 20 fps.
5. The wood tracking system of claim 1 wherein the camera has a resolution of at least 1 megapixel.
