摘要
以测定树叶面积为例介绍了四种测定不规则实物截面面积的方法,并对四种方法的测定结果进行了对比分析.结果表明,四种测定不规则实物截面面积方法是有效的,AutoCAD法与Photoshop法重复性较好,Photoshop法在便捷性方面优于其它三种方法.
Four methods for measuring the cross-sectional area of irregular objects were introduced by taking the measurement of leaf area as an example,and the results of the four methods were compared and analyzed.The results show that the four methods for measuring the cross-sectional area of irregular objects are effective.AutoCAD method and Photoshop method have good repeatability.Photoshop method is superior to the other three methods in terms of convenience.
