摘要:
 立木胸径是评价林木生长状况的重要依据，采用机器视觉的检测方法，实现立木胸径的自动测量。为了快速准确地识别立木边缘，根据立木图像的特点，提出特定方向的归一化分割方法。预处理采用具有保边去噪功能的双边滤波器对立木图像进行滤波，用局部均值法进行一定的像素减少处理。本研究重点是在传统权值矩阵的基础上构造像素点满足特定斜率要求的权值矩阵，两点斜率在45°~135° 2个像素点间的权值为1，在此范围之外的权值为0,构造无向带权图后进行归一化分割。最后利用此算法对30株立木图片在MATLAB 2015环境下进行仿真试验，结果显示立木边缘的平均误提取率为1.21%，小于森林资源清查1.5%的误差要求。
Abstract:
 The DBH is an important basis for evaluating the growth status of trees.In this paper,the automatic measurement of the DBH was achieved by the method of machine vision detection.In order to quickly and accurately identify the edge of the wood,according to the characteristics of the images,this paper presented a specific direction of the normalized segmentation method.Preprocessing used a bilateral filter with edge preserving function to filter the image of the wood,and used the local mean method to perform certain pixel reduction processing.We focused on constructing the weight matrix of pixels to satisfy the specific slope requirement on the basis of the traditional weight matrix.The slope of two pixels was 1 in the specified range,and the weight outside this range was 0,an undirected weighted graph was constructed and the segmentation was normalized.Finally,the algorithm was used to simulate 30 trees in MATLAB 2015 environment.The results showed that the average error rate was 1.21% on the edge of the standing tree,1.5% less than the requirements on forest inventory.
