The influence of clouds is noticeable for laser transmission, and a footprint camera is used to determine laser pointing and to image the ground. However, the cloud inevitably appears in the laser footprint image. In this study, the authors propose a cloud detection scheme for footprint images based on deep learning. First, an adaptive pooling model is proposed according to the characteristics of the cloud region. Next, model fusion was performed based on the SegNet and U\u2010Net training results. Finally, test time augmentation was used to enhance the data and to improve cloud detection accuracy. The experimental results show that the fusion result of the model was approximately 5% better than that of the traditional cloud detection algorithm, which improved the shortcomings of the traditional algorithm, such as poor detection effect for thin clouds and complex underlying cloud surfaces. The related conclusions have certain reference significance for GF\u20107 data processing and related research on footprint images.<\/jats:p>","DOI":"10.1049\/ipr2.12141","type":"journal-article","created":{"date-parts":[[2021,5,8]],"date-time":"2021-05-08T18:20:59Z","timestamp":1620498059000},"page":"2127-2134","update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Cloud detection of GF\u20107 satellite laser footprint image"],"prefix":"10.1049","volume":"15","author":[{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0003-1449-7671","authenticated-orcid":false,"given":"Jiaqi","family":"Yao","sequence":"first","affiliation":[{"name":"College of Geomatics Shandong University of Science and Technology  Qingdao China"},{"name":"Land Satellite Remote Sensing Application Center, Ministry of Natural Resources of P.R.
