Boreal3D
收藏资源简介:
Boreal3D数据集是由西安交通大学和西安电子科技大学的研究团队创建的世界最大森林点云数据集,旨在推动细粒度3D森林结构分析的研究。该数据集包含1000个高度逼真且结构多样的森林样地,涵盖了四个不同的平台,总计48,403棵树和超过353亿个点。每个点都标注了语义、实例和视角信息,每棵树则描述了直径、冠幅、叶面积和总体积等结构参数。数据集的创建基于数字表亲和仿真到现实(Sim2Real)的自动化合成数据生成框架,能够模拟和生成多样化的高质量点云数据。Boreal3D数据集的应用领域主要集中在森林资源监测、生态系统研究以及森林碳储量评估等方面,旨在解决森林结构分析和参数估计中的关键问题。
The Boreal3D Dataset, developed by research teams from Xi'an Jiaotong University and Xidian University, is the world's largest forest point cloud dataset intended to advance research on fine-grained 3D forest structure analysis. This dataset includes 1,000 highly realistic and structurally diverse forest plots spanning four different platforms, boasting a total of 48,403 trees and over 35.3 billion points. Each point is annotated with semantic, instance, and viewpoint information, and each tree is accompanied by structural parameters such as diameter, crown width, leaf area, and total volume. The dataset is constructed using an automated synthetic data generation framework integrating digital proxy and simulation-to-real (Sim2Real) technology, which enables the simulation and generation of diverse high-quality point cloud data. The Boreal3D Dataset finds its primary applications in forest resource monitoring, ecosystem research, forest carbon stock assessment and other relevant domains, aiming to address core challenges in forest structure analysis and parameter estimation.
