摘要
Heteromorphism leaf area of garden trees was measured by CAD-vector method.It was showed that all the coefficients of variation were below 1% when measurement accuracy was relatively high.This method was fit for accuracy area measurement of abnormity leaf,pests and disease leaf,big leaf,small leaf and so on.
CAD矢量法叶面积测量技术是将附有基准面积标尺卡的异形叶片样本图像,经V2R矢量化后,在CAD中测量矢量图形面积,从而准确获取异形叶片样本叶面积的测量技术。1测量设备1架长变焦数码照相机和1台计算机。另外。
