Abstract: A log measurement system for measuring individual logs, each log comprising a log-end face with an applied reference marker of known characteristics. The system includes an image capture system operable or configured to capture a digital image or images of the log-end face of a log to generate a log-end image capturing the log-end face and reference marker. The system also includes an image processing system that is operable or configured to process the captured log-end image to detect or identify the log-end boundary of the log and generate measurement data associated with the log-end boundary in real-world measurement units based on the known characteristics of the reference marker.
