Several technical challenges exist for intelligent, high-precision monitoring, such as computing overhead, area division, and monitoring granularity. In this article, we propose a fine-grained air quality monitoring system based on visual inspection analysis embedded in unmanned aerial vehicle (UAV), referred to as\n            <jats:italic>AQMon<\/jats:italic>\n            . This system employs a lightweight neural network to obtain an accurate estimate of atmospheric transmittance in visual information while reducing computation and transmission overhead. Considering that air quality is affected by multiple factors, we design a dynamic fitting approach to model the relationship between scattering coefficients and PM2.5 concentration in real time. The proposed system is evaluated using public datasets and the results show that\n            <jats:italic>AQMon<\/jats:italic>\n            outperforms four existing methods with a processing time of 13.8 ms.\n          <\/jats:p>","DOI":"10.1145\/3638766","type":"journal-article","created":{"date-parts":[[2023,12,29]],"date-time":"2023-12-29T22:04:32Z","timestamp":1703887472000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["AQMon: A Fine-grained Air Quality Monitoring System Based on UAV Images for Smart Cities"],"prefix":"10.1145","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2793-1441","authenticated-orcid":false,"given":"Shuangqing","family":"Xia","sequence":"first","affiliation":[{"name":"School of Information Science and Technology, Northwest University, China, Shaanxi International Joint Research Centre for the Battery-Free Internet of Things, China, and Xi\u2019an Advanced Battery-Free Sensing and Computing Technology International Science and Technology Cooperation Base, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7526-7269","authenticated-orcid":false,"given":"Tianzhang","family":"Xing","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Northwest University, China, Shaanxi International Joint Research Centre for the Battery-Free Internet of Things, China, and Xi\u2019an Advanced Battery-Free Sensing and Computing Technology International Science and Technology Cooperation Base, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8218-1209","authenticated-orcid":false,"given":"Chase Q.","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Computer Science, New Jersey Institute of Technology, America"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4110-7616","authenticated-orcid":false,"given":"Guoqing","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Northwest University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-5896-5821","authenticated-orcid":false,"given":"Jiadi","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Northwest University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6218-5715","authenticated-orcid":false,"given":"Kang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Northwest University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2024,1,19]]},"reference":[{"key":"e_1_3_1_2_2","unstructured":"Herv\u00e9 Abdi. 2007.
