Segmentation of the communication tower and its accessory equipment based on geometrical shape context from 3D point cloud by Jingru Wang, Cheng Wang, Xiaohuan Xi, Meng Du, Pu Wang, Sheng Nie

“…At first, the CT point cloud is accurately segmented based on region growing and Random Sample Consensus (RANSAC). Then, the point cloud of pole-shaped apart is extended to a certain distance to obtain the buffer point cloud containing AE. …”

A new denoising method for photon-counting LiDAR data with different surface types and observation conditions by Jieying Lao, Cheng Wang, Sheng Nie, Xiaohuan Xi, Hui Long, Baokun Feng, Zijia Wang

“…Second, the local photon filtering direction and threshold are obtained based on the first-step denoising results by RANSAC and elevation frequency histogram, and the local dense noise photons that the first-step cannot be identified are further eliminated. …”
