How to acquire accurate plant area, row spacing, and plant spacing at the same time have been key points for its grow status monitoring and yield prediction. However, accurately detecting small and densely arranged tobacco plants during the rosette stage poses a significant challenge. In Sichuan Province, the contours of scattered tobacco fields with different shapes are not well-extracted. Additionally, there is a lack of simultaneous methods for extracting crucial tobacco planting information, including area, row spacing, and plant spacing. In view of the above scientific problems, we proposed a method to extract the planting information of tobacco at the rosette stage with Unmanned Aerial Vehicle (UAV) remote sensing images. A detection model, YOLOv8s-EFF, was constructed for the small and weak tobacco in the rosette stage. We proposed an extraction algorithm for tobacco field area based on extended contours for different-shaped fields. Meanwhile, a planting distance extraction algorithm based on tobacco coordinates was presented. Further, four experimental areas were selected in Sichuan Province, and image processing and sample label production were carried out. Four isolated tobacco fields with different shapes in four experimental areas were used to preliminarily verify the effectiveness of the model and algorithm proposed. The results show that the precision ranges of tobacco field area, row spacing, and plant spacing were 96.51~99.04%, 90.08~99.74%, and 94.69~99.15%, respectively. And another two experimental areas, Jiange County, Guangyuan, and Dazhai County, Gulin County, and Luzhou, were selected to evaluate the accuracy of the method proposed in the research in practical application. The results indicate that the average accuracy of tobacco field area, row spacing, and plant spacing extracted by this method reached 97.99%, 97.98%, and 98.31%, respectively, which proved the extraction method of plant information is valuable.<\/jats:p>","DOI":"10.3390\/rs16020359","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T08:12:37Z","timestamp":1705392757000},"page":"359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Extraction of Tobacco Planting Information Based on UAV High-Resolution Remote Sensing Images"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9875-9853","authenticated-orcid":false,"given":"Lei","family":"He","sequence":"first","affiliation":[{"name":"School of Software Engineering, Chengdu University of Information Technology, Chengdu 610025, China"},{"name":"Sichuan Province Engineering Technology Research Center of Support Software of Informatization Application, Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunwei","family":"Liao","sequence":"additional","affiliation":[{"name":"School of Software Engineering, Chengdu University of Information Technology, Chengdu 610025, China"},{"name":"Sichuan Province Engineering Technology Research Center of Support Software of Informatization Application, Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxia","family":"Li","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Li","sequence":"additional","affiliation":[{"name":"China Tobacco Corporation Sichuan Provincial Company, Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinglin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, University of Electronic Science and Technology of China, Chengdu 611731, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Wang","sequence":"additional","affiliation":[{"name":"Sichuan Tobacco Company Liangshan Prefecture Company, Xichang 615000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liming","family":"Lu","sequence":"additional","affiliation":[{"name":"College of Agriculture, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sichun","family":"Jian","sequence":"additional","affiliation":[{"name":"Chengdu Song Xing Technology Co., Ltd., Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Qin","sequence":"additional","affiliation":[{"name":"School of Software Engineering, Chengdu University of Information Technology, Chengdu 610025, China"},{"name":"Sichuan Province Engineering Technology Research Center of Support Software of Informatization Application, Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinjun","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Software Engineering, Chengdu University of Information Technology, Chengdu 610025, China"},{"name":"Sichuan Province Engineering Technology Research Center of Support Software of Informatization Application, Chengdu 610225, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105100","DOI":"10.1109\/ACCESS.2019.2932119","article-title":"Unmanned Aerial Vehicles in Agriculture: A Review of Perspective of Platform, Control, and Applications","volume":"7","author":"Kim","year":"2019","journal-title":"IEEE Access"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/j.aac.2022.10.001","article-title":"Understanding the potential applications of Artificial Intelligence in Agriculture Sector","volume":"2","author":"Javaid","year":"2023","journal-title":"Adv.
