| 摘 要： | 数码相机摄入图像时产生的线性几何畸变会给叶片面积的测量带来误差。针对此问题文章改进了Hough变换算法,并用来对叶片畸变图像进行几何校正,然后计算叶片面积。实验表明,该方法适于多种植物的叶面积活体测量,速度快,精度高。 |
| 关 键 词： | 叶面积 数字图像 畸变图像 Hough变换 几何校正 |

| Abstract: | The leaf image taken by digital camera often has linear geometric distortion,it can bring error to the measurement of leaf area.To solve this problem,firstly,this paper improves the Hough transform and uses it to correct the distorted leaf image,then,computes the leaf area.Experiment results affirm that the method introduced is suitable for measuring of many kinds of living leaf area with fast speed and high precision. |
| Keywords: | leaf area digital image distorted image Hough transform geometrical rectification |
