We use a cost-efficient LiDAR system attached to a moving object to estimate the location of the moving object using referenced linear structures. In the stationary state, the accuracy of extracting linear structures is low given the low-cost LiDAR. We propose a merging scheme for the LiDAR data frames to improve the accuracy by using the movement of the moving object. The proposed scheme tries to find the optimal window size by means of an entropy analysis. The optimal window size is determined by finding the minimum point between the entropy indicator of the ideal result and the entropy indicator of the actual result of each window size. The proposed indicator can describe the accuracy of the entire path of the moving object at each window size using a simple single value. The experimental results show that the proposed scheme can improve the linear structure extraction accuracy.<\/jats:p>","DOI":"10.3390\/s22239293","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T07:38:50Z","timestamp":1669793930000},"page":"9293","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["An Entropy Analysis-Based Window Size Optimization Scheme for Merging LiDAR Data Frames"],"prefix":"10.3390","volume":"22","author":[{"given":"Taesik","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Hongik University, Seoul 04066, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinman","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, Inha University, Incheon 22212, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9099-0890","authenticated-orcid":false,"given":"Hong","family":"Min","sequence":"additional","affiliation":[{"name":"School of Computing, Gachon University, Seongnam 13120, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9509-9186","authenticated-orcid":false,"given":"Young-Hoon","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Kyung Hee University, Yongin 17104, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Raj, T., Hashim, F.H., Huddin, A.B., Ibrahim, M.F., and Hussain, A.
