基于Mapinfo的树木叶面积测定方法

The Method for Determining the Leaf Area of Trees in view of Mapinfo

通过扫描仪参照标准计算纸获得树木叶片栅格图像,利用Mapinfo的屏幕跟踪矢量化功能,获得树木叶片轮廓矢量图,进而得到树木叶面积。同时,与方格法、称重法、photoshop法测量结果进行了比较,为测定树木叶面积提供了新途径。

The raster image of tree leaf area was obtained by scanner, consulting standard squared paper, while the vectorgraph of tree leaf figure was acquired by using the vectorizational function of screen trace, then tree leaf area was gained. Furthermore, the outcomes of squared method, weighing method and Photoshop method were compared.
