长白落叶松人工林木材构造计算机视觉分析的研究

应用计算机视觉技术对长白落叶松人工林木材解剖特下及其材性变异规律进行分析，建立了木材解剖特征计算机视觉分析系统，提出了适合木材解剖牲的图象处理分析方法。对木材解剖特征灰度图象的二值化处理过程中，最佳阈值的判定与选择、图象质量的改善等提出了具体的实现方法。测量了长白落叶松人工林木材分子的几何尺寸，如管胞的径向和弦向外径和内径，管胞的壁厚，以及生长轮内木材的胞壁率等，并对管胞分子的边缘进行检测。得出了

ANALYSIS OF COMPUTER VISION ON WOOD STRUCTURE OF LARIX H. IN MAN-MADE FOREST

The paper analyzed the wood anatomical feature and wood structure variation of Larix olgensis H. in man-made forest by computer vision technique. The analysis system of computer vision and the suitable analysis method of pattern processing on wood anatomical feature were both established. The accurate way for determining and choosing the optimal threshold value and improving the image quality in the grey image binary of wood anatomical feature were also given. The geometric sizes of wood molecules of Larix olgensis H. in man-made forest were measured. such as the outer and interior diameters of radial and tangential direction tracheid. the thickness of tracheid as well as the cell wall ratio in wood growth rings. etc This paper finally obtained the variation rule of the timber quality of growth rings and wood anatomical feature and structure of Larix Sogensis H. in man-made forest.
