In today’s sawmills, the accurate rotation and positioning of the logs, prior to chipping and sawing, is an essential component in maximizing the volume of the lumber produced from each log. Previous studies, and the work conducted here, have shown that the common methods of rotating the logs as they enter the canter line can have large errors leading to very significant losses in lumber recovery, especially for small, swept or crooked logs. Sawmills are also moving to higher and higher processing speeds to reduce production costs, making log positioning even more difficult. In this project a real-time camera based system was developed that measures the incremental rotation of each log (as it is being rotated by the log rotator) and provides feedback that can be used to control the degree of rotation with much greater accuracy. In addition, a log rotation verifier was developed that, using the existing mill pre- and post-rotation scanning systems, measures the actual rotation of the log to continuously verify the accuracy of the system.
