摘要
三维激光扫描技术是近年来能够以超高精度和效率获得空间信息的新技术。仪器扫描所获取的原始数据里,为了避免精度的损失,则需对所获取的点云数据进行配准去噪等处理才能更加精确地提取到建筑物的特征信息以及提高建筑物建模精度。本文利用徕卡ScanStation C10三维激光扫描仪获得某市魔方时代广场的三维激光点云数据,制定了科学合理的建筑物三维点云和纹理照片的外业采集流程,利用先进有效的技术对获取的数据做了预处理,并且对其中的方法做出分析与总结。结果表明,建立模型后,可以达到预期的结果。
With the rapid development of modern cities, the construction of digital cities has been continuously deepened and promoted, three-dimensional laser scanning technology is a new technology that can obtain spatial information with ultra-high accuracy and efficiency in recent years. In order to avoid the loss of accuracy in the original data obtained by instrument scanning, it is necessary to carry out registration and denoising processing on the acquired point cloud data in order to extract the feature information of the building more accurately and improve the building modeling accuracy. In this paper, the Leica scanstation C10 3 D laser scanner is used to obtain the 3 D laser point cloud data of the Rubik′s cube times square of a city, and a scientific and reasonable field collection process of 3 D point cloud and texture photos of buildings is developed. The obtained data is preprocessed by using advanced and effective technologies, and the methods are analyzed an summarized. The results show that the expected results can be achieved after the model is established.
