TLS技术在森林资源调查中的应用现状与展望

Application Status and Prospect of TLS in Forest Resources Inventory

森林资源调查是森林经营管理的基础,传统的调查与监测方法工作量大,费时费力,难以满足目前的监测研究需求。地基激光雷达(Terrestrial Laser Scanning,简称TLS)是一种主动遥感技术,提供一种非破坏性三维测量手段,能够获取目标对象高精度3D点云数据,自动化提取森林调查属性参数,在森林参数反演方面具有独特优势。介绍了TLS工作原理、技术特点以及林业应用现状,讨论了TLS在森林调查中的优缺点,并对其未来在林业应用前景进行了分析和展望。

The investigations of forest resource is the basis for forest management,and the traditional methods of investigation and monitoring is time consuming and laborious.At present,it is difficult to meet the demand of monitoring research.Terrestrial laser scanning（TLS）is a kind of active remote sensing technology,which can provide a non-destructive three-dimensional measuring means,obtain high precision 3D point cloud data,extract forest property parameters automatically,and enjoy unique advantages in forest parameters retrieval.This paper mainly introduced the working principle and technical characteristics of TLS,the application status in forest sector.The advantages and disadvantages of TLS in forest investigation were discussed,and the prospect of future application in forestry was analyzed and prospected.
