| 摘 要： | 采用数字图像处理方法对毛白杨叶片进行长、宽、面积的测算,并应用Hough变换对叶片畸变图像进行校正,取得了可靠的数据,建立了叶片长、宽、长宽乘积和面积的回归方程,结果有着显著的相关性,为植物叶面积快速估算提供了一条比较好的途径.

| Abstract: | In this paper,we applied the digital image processing methods to measure the length,wide and area of the PopulustomentosaCarr leaves,we used Hough transformations to correct the geometry distortion of the leaf photos,and achieved reliable data.At last,we established regression equations between the length,wide,the product of length and wide and the area.The results are proved to have a significant correlation,and it also provides a good way to a rapid estimation of plant leaf. |
