王金亮导师小组论文在SCI/SCIE二区期刊Computers and Electronics in Agriculture上线发表

2021928日,以刘钱威(云南师范大学地理学部,地图学与地理信息系统专业2019级硕士研究生)为第一作者、王金亮教授为通讯作者撰写题为“Target-free ULS-TLS point-cloud registration for alpine forest lands”论文在SCI/SCIE期刊Computers and Electronics in Agriculture(二区,2020IF 5.565)上线发表(https://doi.org/10.1016/j.compag.2021.106460)。

机载激光雷达与地基激光雷达具有互补的扫描视角,将两者的源数据进行配准可以获取更为完整的森林点云数据,对于提取森林信息具有重大帮助。然而受数据密度、扫描的林分冠层形状不一致等方面影响,两者的配准面临难题。研究以香格里拉市作为研究区,提出一种树高点配准方法,该方法从DSMDigital Surface Model)中获取树高点,搜索配对树高点,通过SVDSingular Value Decomposition)分解获取旋转与平移矩阵完成粗配准,最后通过最邻近点迭代SVD分解实现精配准。结果表明:(1)该方法在本文的样地中平均精度为0.43m,平均运行时间不超过1s,在斜坡(2~18°)林地中具有较好的适用性。(2)通过探究树干点搜索窗口变化的影响,发现3m*3m最为适合。

摘要:Modern laser scanning techniques have been commonly used for forest land studies. Complementary scanning capabilities can be particularly obtained using unmanned aerial vehicle laser scanning (ULS) and terrestrial laser scanning (TLS) technologies. The registration of the ULS and TLS data can thus lead to more comprehensive data acquisition and information extraction in forest lands. However, this registration process is typically hindered by problems of data density and inconsistency of the scanned forest canopy shape. In this paper, we propose a tree height registration (TR) method for ULS-TLS point-cloud registration, and apply this method to the alpine forest land of the Shangri-La City of the Northwestern Yunnan Province in China. The tree height points are obtained from a digital surface model (DSM), which contains isosurface points of the forest structures. Rotation and translation matrices are then calculated through singular value decomposition (SVD), and rough registration is completed. Finally, fine registration is achieved through nearest-neighbor iterative SVD. The results show that the proposed method can effectively register ULS and TLS forest data samples, with an average accuracy of 0.43m. The method has an average running time of less than 21 s through 3m-by-3m window size to search tree height point for registration, and also shows good applicability in forest lands with slopes in the range of 2-18◦.Moreover, the best outcomes were obtained for a 3m-by-3m window size.
