    摘要:

    为解决当前测量树高方法中存在测量误差大,测量不便等问题,提出一种基于鱼眼镜头的树高测量方法。该方法首先利用鱼眼镜头成像模型确立世界坐标系到图像像素坐标系的变换关系;然后以畸变系数的等距投影模型为基础,利用Scaramuzza鱼眼相机标定方法求解参数并建立测量系统模型;最后利用图像处理技术对实验图像进行轮廓提取,分割及极值点提取,实现对树高的测量。通过本文提出的测量方法对树高进行测量,实验结果表明:本文提出的测量方法测量误差在-0.196 m~0.195 m之间,树木测量最高相对误差为2.75%,平均相对误差为1.505%,说明该方法有效减小了测量误差,具有很高的精确性,同时测量方法简便,可操作性强。

    Abstract:

    In order to the problems of large measurement error and inconvenient method in measuring tree height methods, a tree height measurement method based on fish-eye lens is proposed. Firstly, the fish-eye lens imaging model is used to establish the transformation relationship from the world coordinate system to the image pixel coordinate system. Secondly, the calibration method of Scaramuzza fisheye camera is used to solve the parameters and establish the measurement system model based on the isometric projection model with distortion coefficient. Finally, the image processing technology is used to extract and segment the experimental image contour and extract the extreme points measurement of tree height. The tree height is measured by the measurement method proposed in this paper. The experimental results show that the measurement error of the proposed method is between-0.196 m and 0.195 m, the maximum relative error of tree measurement is 2.75%, and the average relative error is 1.505%. It shows that the method can effectively reduce the measurement error and has high accuracy. At the same time, the measurement method is simple and easy to operate.
