However, geometric misalignments still exist between some aerial optical images and airborne LiDAR point clouds. To eliminate such misalignments, we extended a method for registering close-range optical images with terrestrial LiDAR data to a variety of large-scale aerial optical images and airborne LiDAR data. The fundamental principle is to minimize the distances from the photogrammetric matching points to the terrestrial LiDAR data surface. Except for the satisfactory efficiency of about 79 s per 6732 \u00d7 8984 image, the experimental results also show that the unit weighted root mean square (RMS) of the image points is able to reach a sub-pixel level (0.45 to 0.62 pixel), and the actual horizontal and vertical accuracy can be greatly improved to a high level of 1\/4\u20131\/2 (0.17\u20130.27 m) and 1\/8\u20131\/4 (0.10\u20130.15 m) of the average LiDAR point distance respectively. Finally, the method is proved to be more accurate, feasible, efficient, and practical in variety of large-scale aerial optical image and LiDAR data.<\/jats:p>","DOI":"10.3390\/s18061770","type":"journal-article","created":{"date-parts":[[2018,6,1]],"date-time":"2018-06-01T04:37:46Z","timestamp":1527827866000},"page":"1770","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Registration of Aerial Optical Images with LiDAR Data Using the Closest Point Principle and Collinearity Equations"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6829-3637","authenticated-orcid":false,"given":"Rongyong","family":"Huang","sequence":"first","affiliation":[{"name":"Guangxi Laboratory on the Study of Coral Reefs in the South China Sea, Guangxi University, Nanning 530004, China"},{"name":"School of Marine Sciences, Guangxi University, Nanning 530004, China"},{"name":"Coral Reef Research Centre of China, Guangxi University, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunyi","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430079, China"},{"name":"Collaborative Innovation Center for Geospatial Technology, Wuhan University, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5044-7327","authenticated-orcid":false,"given":"Kun","family":"Hu","sequence":"additional","affiliation":[{"name":"Institute of Electronics, Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Key Laboratory of Technology in Geo-Spatial Information Processing and Application System, Chinese Academy of Sciences, Beijing 100190, China"},{"name":"Department of Civil, Environmental and Geodetic Engineering, Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1016\/S0924-2716(99)00009-X","article-title":"Airborne laser scanning\u2014Present status and future expectations","volume":"54","author":"Ackermann","year":"1999","journal-title":"ISPRS J.
