Abstract: A method and system for monitoring the quality of log cutting either off-line or in real-time is based on optical measurement of half-squared or full-squared cants characteristics as produced at primary or secondary cutting stage, so as to increase the proportion of high-value wood pieces that can be recovered from full squared-cants produced at the sawing stage. The log is fed lengthwise to a primary cutting station (canter) capable of producing the first pair of opposing cut faces, while guiding the log substantially in a direction of the machine axis. The profile of the peripheral log surface at a plurality of cross-sections along the machine axis is measured to generate corresponding post-cut profile data, from which an estimation of log raw profile characteristics is made, to generate corresponding raw profile data. Then, from post-cut and raw profile data, resulting data on at least one parameter related to the cutting quality of the log.
