Due to the design constraints of the lander, there is no additional installation position for volume measurement equipment. To fully use the sensors already installed, a collected soil volume measurement method is designed in this paper based only on a single monitoring camera. This method uses a sequence of images of the collection area captured by the camera mounted on the acquisition arm to accurately reconstruct the terrain of the collection area surface before and after soil acquisition. Additionally, bi-temporal dense point clouds are reconstructed. Based on the area of change associated with soil collection, the constructed dense point clouds are compared according to the topographic characteristics of the area to estimate the volume of soil collected. Experiments show that the method is stable and reliable and can meet the requirements of actual measurement tasks.<\/jats:p>","DOI":"10.3390\/s18103394","type":"journal-article","created":{"date-parts":[[2018,10,12]],"date-time":"2018-10-12T02:58:04Z","timestamp":1539313084000},"page":"3394","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Volume Measurement Method for Lunar Soil Collection Based on a Single Monitoring Camera"],"prefix":"10.3390","volume":"18","author":[{"given":"Shaowen","family":"Ding","sequence":"first","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410072, China"}]},{"given":"Xiaohu","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410072, China"},{"name":"School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510000, China"}]},{"given":"Qifeng","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410072, China"}]},{"given":"Lichun","family":"Li","sequence":"additional","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410072, China"},{"name":"Beijing Aerospace Control Center, Beijing 100000, China"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Aerospace Science and Engineering, National University of Defense Technology, Changsha 410072, China"},{"name":"Beijing Institute of Space Mechanics &amp; Electricity, Beijing 10000, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.3724\/SP.J.1218.2013.00009","article-title":"A Novel End-Effector for Lunar Sample Acquisition and Return","volume":"35","author":"Li","year":"2013","journal-title":"Robot"},{"key":"ref_2","first-page":"18","article-title":"Application of Time-of-Flight Camera for Relative Measurement of Non-Cooperative Target in Close Range","volume":"9","author":"Liang","year":"2016","journal-title":"J.
