Sparse Representation Denoising Framework for 3-D Building Reconstruction From Airborne LiDAR Data.
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing（2016）
摘要
Random noise has a serious impact on the performance of three-dimensional (3-D) building reconstruction from airborne LiDAR data. In this paper, a sparse representation denoising framework for building roofs from airborne LiDAR is proposed. In the proposed framework, both the random noise and the local structural information are considered. At first, a systematic analysis for the random noise of t...
