地面激光扫描三维重建技术的实验教学平台构建

摘要

建立地面激光扫描三维重建技术的实验教学平台,该平台利用多媒体教学手段介绍理论知识、提供点云数据获取和三维重建的技术路线和数据处理方法.设计出实验教学平台总体框架,在此框架下建立以技术原理、技术流程和工程应用案例为主要内容的教学平台,以专业点云软件和在线式实验环境为依托,建立了实验教学平台网站,开放若干自主学习型、综合设计型和研究创新型实验项目,使学生熟练掌握地面激光扫描三维重建技术,培养并提高学生的学习和研究能力.%This paper researched an experimental teaching platform of 3D reconstruction technology of terrestrial laser scanning. Theoretical knowledge is introduced by multimedia teaching tools, technology roadmap and data processing methods of point cloud data acquisition and 3D reconstruction are provided. The overall framework of experimental teaching platform is designed to build main content on teaching platform including technical principles, technical processes and engineering case, and experimental platform consists of professional point cloud software and online experimental environment. The platform website is constructed finally. Depending on its operation, the self-learning, design-integrated and research-innovative pilot projects are opened for students. Accordingly, 3D reconstruction technology of terrestrial laser scanning can be mastered greatly, and the capacity of learning and research skill can be improved by fully using the platform resources.
