- 摘要:
- 为了快速测定苹果叶面积，以Matlab软件为工具对数字图像进行解析求解叶面积，解析结果通过与叶面积仪、剪纸法测定结果进行对比，分析基于Matlab解析数字图像求解苹果叶面积的准确性。结果表明：基于Matlab解析数字图像的方法与叶面积仪测定苹果叶面积的结果无显著差异（配对检验P（P>|t|=0.167>0.05）)，剪纸法测定结果较低于Matlab解析法测定结果；该研究结果表明，基于Matlab解析数字图像求解苹果叶面积的方法经济、准确且快速，可作为一种新的测定苹果叶面积的方法进行推广应用。
- Abstract:
- In order to rapidly measure leaf area of apple，the method based on analysis of digital image by the Matlab software was developed.Then the accuracy for Matlab analysis of digital image was determined by comparing it with the leaf area meter and copy method.The results showed that there was no significant difference（paired test P（P>|t|=0.167>0.05）) between the method of Matlab analysis of digital image and the leaf area meter，and the results of copy method were significantly lower than the results measured with the method of Matlab analysis of digital image.In this study，it could be concluded that the method for Matlab analysis of digital image was low-cost，efficient and accurate，could be used as a new method for measuring the leaf area of apple.
