The remote and autonomous operations in such places are currently increasing with the aid of technology improvements in communications and processing hardware. Virtual and augmented reality provide applications for crew training and remote monitoring, which also rely on 3D environment reconstruction techniques with near real-time requirements for environment inspection. Nowadays, most techniques rely on offline data processing, heavy computation algorithms, or mobile robots, which can be dangerous in confined environments. Other solutions rely on robots, edge computing, and post-processing algorithms, constraining scalability, and near real-time requirements. This work uses an edge-fog computing architecture for data and processing offload applied to a 3D reconstruction problem, where the robots are at the edge and computer nodes at the fog. The sequential processes are parallelized and layered, leading to a highly scalable approach. The architecture is analyzed against a traditional edge computing approach. Both are implemented in our scanning robots mounted in a real power plant. The 5G network application is presented along with a brief discussion on how this technology can benefit and allow the overall distributed processing. Unlike other works, we present real data for more than one proposed robot working in parallel on site, exploring hardware processing capabilities and the local Wi-Fi network characteristics. We also conclude with the required scenario for the remote monitoring to take place with a private 5G network.<\/jats:p>","DOI":"10.3390\/s22124494","type":"journal-article","created":{"date-parts":[[2022,6,15]],"date-time":"2022-06-15T01:39:54Z","timestamp":1655257194000},"page":"4494","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["An Edge-Fog Architecture for Distributed 3D Reconstruction and Remote Monitoring of a Power Plant Site in the Context of 5G"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2576-2760","authenticated-orcid":false,"given":"Vinicius","family":"Vidal","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Juiz de Fora, Juiz de Fora 36036-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2735-4792","authenticated-orcid":false,"given":"Leonardo","family":"Hon\u00f3rio","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Juiz de Fora, Juiz de Fora 36036-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6916-700X","authenticated-orcid":false,"given":"Milena","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, Federal Center for Technological Education of Rio de Janeiro, Rio de Janeiro 20271-110, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2312-7042","authenticated-orcid":false,"given":"Mario","family":"Dantas","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Federal University of Juiz de Fora, Juiz de Fora 36036-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8645-0464","authenticated-orcid":false,"given":"Maria","family":"Aguiar","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Federal University of Juiz de Fora, Juiz de Fora 36036-900, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1380-971X","authenticated-orcid":false,"given":"Miriam","family":"Capretz","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Western University, London, ON N6A 1G8, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1016\/j.dcan.2020.12.001","article-title":"Robot and its living space: A roadmap for robot development based on the view of living space","volume":"7","author":"Cai","year":"2020","journal-title":"Digit.
