The present disclosure describes methods and systems for virtually calibrating geometric sensors with overlapping fields of view. In some embodiments, a geometric sensor may be virtually calibrated by applying a correction value to profile data obtained by the geometric sensor to generate adjusted profile data. The correction factor may be determined based at least in part on X-Y offsets and/or rotational offsets of prior profile data obtained by the geometric sensor relative to corresponding profile data obtained by a reference geometric sensor, and may be recalculated or updated as new sets of profile data are obtained.

Embodiments provide a conveyor for conveying loads of lumber through a lumber kiln or other structure without the use of lumber carts or pushers. The conveyor may include a plurality of rollers arranged to form a flow path through the lumber kiln. Groups of the rollers may be driven by separate drives that are configured to rotate the rollers in opposite rotary directions and/or at variable speeds. Some or all of the drives may be operable independently of the other drives to transport loads of lumber at different speeds/directions in adjacent areas of the lumber kiln. In the event of a fire or a shut-down, the rollers in the proximal half of the kiln and those in the distal half of the kiln can be rotated in opposite directions to evacuate loads quickly from both ends.

Embodiments provide methods, apparatuses, and systems for identification of wood species based on one or more pitch characteristics. A workpiece may be exposed to a beam of radiation from a radiation source. The beam of radiation may cause pitch on or within the workpiece to emit visible light. The emitted light may be imaged and used to determine pitch content, pitch location. a pitch deposition pattern, pitch emission wavelength, and/or other characteristics of the workpiece. One or more of these characteristics may be used to identify a tree species or group of tree species from which the workpiece was cut or manufactured.
Embodiments provide a multi-pass kiln with two or more chambers, an entrance and an exit at a proximal end of the kiln, and a reciprocal flow path extending through the kiln from the entrance to the exit.
