The mangrove forests of northeast Hainan Island are the most species diverse forests in China and consist of the Dongzhai National Nature Reserve and the Qinglan Provincial Nature Reserve. The former ...
Developing accurate methods to map vegetation structure in tropical forests is essential to protect their biodiversity and improve their carbon stock estimation. We integrated LIDAR (Light Detection a...
Forest plantations are an important source of terrestrial carbon sequestration. The forest of Robinia pseudoacacia in the Yellow River Delta (YRD) is the largest artificial ecological protection fores...
Developing an accurate model for estimating the forest structural parameters of planted forests is crucial for forest productivity predictions and can provide a better understanding of the carbon cycl...
Inventories of tropical forest aboveground biomass (AGB) are often imprecise and sparse. Increasingly,?airborne?Light Detection And Ranging (LiDAR) and satellite optical wavelength sensor data are use...
Mapping 3D vegetation structure in wetlands is important for conservation and monitoring. Openly accessible country-wide Airborne Laser Scanning (ALS) data-using light detection and ranging (lidar) te...
Light detection and range (LiDAR) intensity is an important feature describing the characteristics of a target. The direct use of original intensity values has limitations for users, because the same ...
Surface Canopy Water (SCW) is the intercepted rain water that resides within the tree canopy and plays a significant role in the hydrological cycle. Challenges arise in measuring?SCW?in remote areas u...
Light detection and ranging (LiDAR) has become a commonly-used tool for generating remotely-sensed forest inventories. However, LiDAR-derived forest inventories have remained uncommon at a regional sc...
Airborne laser scanning has proven useful for rapid and extensive documentation of historic cultural landscapes after years of applications mapping natural landscapes and the built environment. The re...
Remotely sensed images with low resolution can be effectively used for the large-area monitoring of vegetation restoration, but are unsuitable for accurate small-area monitoring. This limits researche...
Airborne light detection and ranging (lidar) has proven to be a useful data source for estimating forest inventory metrics such as basal area (BA), volume, and aboveground biomass (AGB) and for produc...
A low-cost but accurate remote-sensing-based forest-monitoring tool is necessary for regularly inventorying tree-level parameters and stand-level attributes to achieve sustainable management of timber...
本文以实现移动小型智能化系统的实时自主定位为目标,针对激光里程计误差累计大,旋转估计不稳定,以及观测信息利用不充分等问题,提出一种LiDAR/IMU紧耦合的实时定位方法—Inertial-LOAM.数据预处理部分,对IMU数据预积分,降低优化变量维度,并为点云畸变校正提供参考.提出一种基于角度图像的快速点云分割方法,筛选结构性显著的点作为特征点,降低点云规模,保证激光里程计的效率。
获取堤防中心线、堤顶堤坡和断面等特征信息对于堤防破损检测和安全评估具有重要意义。LiDAR技术为堤防检测工作提供了便利,LiDAR生成的DTM是一种连续化的地表数据,用于堤防特征信息提取具有工作量小、数据精度高的极大优势。本文提出了一种使用机载LiDAR生成的DTM数据开展堤防特征信息提取方法,采用圆环探测实现堤防中心线生成,与常规方法相比可以很好地规避堤防因侵蚀、垮塌等原因造成中心线数据变形、截...
