不确定性理论在激光雷达数据地物分类方面的应用研究进展

摘要

激光扫描与测距（LIDAR）数据地物分类是近年来测绘及相关领域内的研究热点。由于数据获取、传输以及激光本身特性的影响，使得LIDAR数据与地物信息的对应关系存在不确定性，而不确定性理论在处理数据不确定方面扮演着十分重要的角色。综合论述了近年来常用的LIDAR数据地物分类的特征及其特性、地物分类的应用领域以及国内外利用不确定性理论进行LIDAR数据地物分类的方法，并分析其优缺点，最后给出了总结与展望。%Feature classification of light detection and ranging (LIDAR) data is a research focus in the field of surveying and mapping in recent years. The corresponding relationship between LIDAR data and feature informa⁃tion is uncertain for the influence of data acquisition, transmission and laser characteristics. The uncertain theory plays a very important role in dealing with uncertain data. The features, characteristics, application fields of com⁃mon used LIDAR data feature classification in recent years and the method of LIDAR data feature classification us⁃ing uncertain theory in China and foreign countries are summarized. The advantages and disadvantages of the meth⁃od are analyzed. Finally, the summary and prospect are presented.
