Popis: Sales of harvested wood is based on harvester head measurements. Therefore, an accurate length measurement is important when a log is being processed on a forest harvester. A stereo camera pair was mounted to the harvester head and the motions of the harvester head and the log were estimated using off-line machine vision algorihms. Preliminary tests with seven different logs had a maximum error of 12 mm where the mean absolute error between measured and estimated log lengths was 0.09%.
