Tree-ring growth measurements automation using machine vision

The article discusses the problem of automating tree-ring growth measurements using a vision system. Imaging using the scatter method has been proposed, resulting in greater contrast. The article contains a description of the test stand and analysis of the measurement resolution. The filtration and segmentation algorithm has been described. Implementation problems were also discussed. Presented solution also applies to porous wood. The weak point of the method is the imaging time and the need for relative movement between the optical system and the wood being imaged.
