基于数字图像法树木年轮宽度测量方法研究

Study on the method of tree ring width measurement based on digital image method

针对树木年轮图像在复杂背景下分割难的问题,提出了利用绘图工具软件AutoCAD测量年轮宽度的数字图像法,分别应用数字图像测量法和千分式手工测量相同方向10年树龄各年的年轮宽度。结果表明,采用数字图像法能够进行年轮宽度的较快速、准确地测量,且具有测量方法简单、设备普及率高、经济成本低等优点。

For tree rings, the dificulty of image segmentation under complex background, it puts for-ward using the drawing tools software AutoCAD tree ring width measurement metliital image measurement metliod resjoectively and 10 years old thousand fraction of msame direction in each of the annual ring width. The results show that digital image metJiod is used to an-nual ring width of more rapid, accurate measurement, and the measuring methhigh penetration rate, low economic cost advantages.
