Sensing"],"abstract":"<jats:p>Impact craters are extensively researched geological features that contribute to various aspects of lunar science, such as evaluating the model age, regolith thickness, etc. The method for identifying impact craters has gradually transitioned from manual counting to automated identification. Automatic crater detection based on the digital elevation model (DEM) is commonly used to detect larger craters. However, using only DEM has limitations in discerning smaller craters (diameter &lt; ~1 km). This study utilizes an improved Faster R-CNN algorithm and the Kaguya Terrain Camera (TC) morning map to detect small impact craters in the Chang\u2019e-5 (CE-5) landing site. It uses model fusion to improve the precision of small crater identification. The results show a recall rate of 96.33% and a precision value of 90.19% for craters with diameters exceeding 200 m. The model found a total of 187,101 impact craters in the CE-5 region. The spatial distribution density of impact craters with diameters ranging from 100 m to 200 m is approximately 2.5706\/km2. For craters with diameters ranging from 200 m to 1 km, the average spatial distribution density is about 0.9016\/km2. By the unbiased impact crater density of chronological analysis, the model age of the Im2 and Em4 geological units in the CE-5 region is 3.78 Ga and 2.07 Ga, respectively.<\/jats:p>","DOI":"10.3390\/rs16020344","type":"journal-article","created":{"date-parts":[[2024,1,15]],"date-time":"2024-01-15T11:15:01Z","timestamp":1705317301000},"page":"344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Identification of Lunar Craters in the Chang\u2019e-5 Landing Region Based on Kaguya TC Morning Map"],"prefix":"10.3390","volume":"16","author":[{"given":"Yanshuang","family":"Liu","sequence":"first","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2157-2767","authenticated-orcid":false,"given":"Jialong","family":"Lai","sequence":"additional","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minggang","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Science, Guilin University of Technology, Guilin 541006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6658-2363","authenticated-orcid":false,"given":"Jiannan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geological Survey and Evaluation of Ministry of Education, China University of Geosciences, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaofei","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiqing","family":"Qian","sequence":"additional","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiahao","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Science, Jiangxi University of Science and Technology, Ganzhou 341000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3256","DOI":"10.1029\/2002JE001985","article-title":"Ages and Stratigraphy of Mare Basalts in Oceanus Procellarum, Mare Nubium, Mare Cognitum, and Mare Insularum","volume":"108","author":"Hiesinger","year":"2003","journal-title":"J.
