一种新的基于地面激光雷达数据正射影像图制作方法

摘要

针对古建筑群建筑物密集,空间狭窄,遮挡较严重地情况,提出了一种新的基于地面激光雷达数据制作古建筑正射影像的方法.该方法是基于地面激光雷达获取的点云数据和数码影像,根据影像定向理论和现有的软件提出的一种新的技术流程.实验证明该技术流程制作工序简单,提高了效率,结果能够满足精度要求,具有一定的现实意义,能够应用于工程.%For the density of construction,narrow space,and blocking severely of the ancient buildings,a new method of making orthophotos is described based on the data of T-LIDAR.This method is a new technological process using cloud points and digital images,the theory of image orientation and the existing softwares.The Experiments show that the technical process has the simple manufacturing processes,and improve efficiency.The results can meet the accuracy requirements.It can be used in engineering,and has some practical significance.
