The objective of the study was the development of an automatic measurement method for tree ring increments using a vision system combined with an XYZ scanner. The elaborated method allows for the measurement of increments on cross-section a tree discs or on increment bores. The solution utilizes the XYZ scanner equipped with a vision system, enabling increment measurement during sample scanning. The vision system collects and analyses images of a wood sample. The splicing of partial images enables the construction of a full image of rings, visible on the entire sample surface. Image construction of the studied sample based on a set of magnified partial pictures enables the attainment of very high resolutions, which in top end optical systems, greatly surpasses the resolutions obtained using traditional scanners. The system works automatically and the algorithm of the increment measurement is based on the image analysis of the sample area and is realized in the acquisition time of partial pictures by the vision system. Configuration of the measurement system enables selection of the field of view and measuring resolution. The maximum obtained in the presented system is 0.001 mm.
