摘要
近年来,新兴机载全波形Li DAR技术在摄影测量与遥感领域受到广泛关注。其相比传统机载Li DAR的优势在于它对后向散射回波信息进行了完整的数字化记录。波形分解是波形数据处理的重要环节,通过波形分解不仅仅可以得到高质量的三维点云产品,还能够提高DEM的生成精度并辅助点云的精确分类,随着研究的不断深入,全波形数据将在更多领域发挥更大的实用效益。
Recently,the new airborne full waveform Li DAR has been paid wide attention in the field of Photogrammetric and Remote Sensing. Compared with traditional airborne Li DAR,the advantage of full waveform Li DAR is that it digitalizes the full backscattered information. Decomposition is the most important step in waveform data processing,which could not only derive 3 dimensional point cloud with high quality,but also improve DEM generation and points cloud classification. As the relevant research develops,the full waveform data will be more practical in the future.
