Power engineering device monitoring by detecting key objects is important for power safety. In this paper, we introduce a novel method for the reconstruction of self-supporting pylons widely used in high voltage power-line systems from airborne LiDAR data. Our work constructs pylons from a library of 3D parametric models, which are represented using polyhedrons based on stochastic geometry. Firstly, laser points of pylons are extracted from the dataset using an automatic classification method. An energy function made up of two terms is then defined: the first term measures the adequacy of the objects with respect to the data, and the second term has the ability to favor or penalize certain configurations based on prior knowledge. Finally, estimation is undertaken by minimizing the energy using simulated annealing. We use a Markov Chain Monte Carlo sampler, leading to an optimal configuration of objects. Two main contributions of this paper are: (1) building a framework for automatic pylon reconstruction; and (2) efficient global optimization. The pylons can be precisely reconstructed through energy optimization. Experiments producing convincing results validated the proposed method using a dataset of complex structure.<\/jats:p>","DOI":"10.3390\/rs8030243","type":"journal-article","created":{"date-parts":[[2016,3,15]],"date-time":"2016-03-15T11:10:18Z","timestamp":1458040218000},"page":"243","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["A Stochastic Geometry Method for Pylon Reconstruction from Airborne LiDAR Data"],"prefix":"10.3390","volume":"8","author":[{"given":"Bo","family":"Guo","sequence":"first","affiliation":[{"name":"Key Laboratory for Geo-Environment Monitoring of Coastal Zone of the National Administration of Surveying, Mapping and GeoInformation &amp; Shenzhen Key Laboratory of Spatial Smart Sensing and Services, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"},{"name":"College of Information Engineering, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"}]},{"given":"Xianfeng","family":"Huang","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Luoyu Road 129, Wuhan 430079, China"},{"name":"Collaborative Innovation Center of Geospatial Technology, Wuhan University, Luoyu Road 129, Wuhan 430079, China"}]},{"given":"Qingquan","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory for Geo-Environment Monitoring of Coastal Zone of the National Administration of Surveying, Mapping and GeoInformation &amp; Shenzhen Key Laboratory of Spatial Smart Sensing and Services, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"}]},{"given":"Fan","family":"Zhang","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Luoyu Road 129, Wuhan 430079, China"},{"name":"Collaborative Innovation Center of Geospatial Technology, Wuhan University, Luoyu Road 129, Wuhan 430079, China"}]},{"given":"Jiasong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Key Laboratory for Geo-Environment Monitoring of Coastal Zone of the National Administration of Surveying, Mapping and GeoInformation &amp; Shenzhen Key Laboratory of Spatial Smart Sensing and Services, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"}]},{"given":"Chisheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Geo-Environment Monitoring of Coastal Zone of the National Administration of Surveying, Mapping and GeoInformation &amp; Shenzhen Key Laboratory of Spatial Smart Sensing and Services, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"},{"name":"College of Information Engineering, Shenzhen University, Nanhai Road 3688, Shenzhen 518060, China"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"485","DOI":"10.1109\/TPWRD.2009.2035427","article-title":"A survey of mobile robots for distribution power line inspection","volume":"25","author":"Katrasnik","year":"2010","journal-title":"IEEE Trans.
