In the method, a line through the centre of concentric circles is used as a template in which orthogonal directions can be determined from an angle of circumference that corresponds to a diameter. By using three lines through the centre of concentric circles, based on the invariance of the cross-ratio, an image at the centre of the concentric circles can be used to obtain the vanishing point. The intrinsic parameters of the camera can be computed based on the constraints of the orthogonal vanishing points and the imaged absolute conic. The lens distortion causes points in the template to have a position offset. In the proposed method, we optimize the positions of the distortion points such that they gradually approach those of the ideal points. The simulated and real-world experiments demonstrate that the proposed method is efficient and feasible.<\/jats:p>","DOI":"10.1155\/2018\/6182953","type":"journal-article","created":{"date-parts":[[2018,4,22]],"date-time":"2018-04-22T19:31:50Z","timestamp":1524425510000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["Method of Camera Calibration Using Concentric Circles and Lines through Their Centres"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4896-2247","authenticated-orcid":true,"given":"Yue","family":"Zhao","sequence":"first","affiliation":[{"name":"Institute of Mathematics and Statistics, Yunnan University, Cuihu, Kunming 650091, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuechun","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Mathematics and Statistics, Yunnan University, Cuihu, Kunming 650091, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengli","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Mathematics and Statistics, Yunnan University, Cuihu, Kunming 650091, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/2802343"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/149852"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/732937"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/S0031-3203(02)00225-X"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-24670-1_15"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2007.06.012"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.patcog.2009.10.003"},{"year":"1952","key":"9"},{"year":"2003","key":"10"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/AMR.798-799.638"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/34.888718"}],"container-title":["Advances in Multimedia"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/am\/2018\/6182953.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/am\/2018\/6182953.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/am\/2018\/6182953.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,4,22]],"date-time":"2018-04-22T19:32:04Z","timestamp":1524425524000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/am\/2018\/6182953\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":11,"alternative-id":["6182953","6182953"],"URL":"https:\/\/doi.org\/10.1155\/2018\/6182953","relation":{},"ISSN":["1687-5680","1687-5699"],"issn-type":[{"type":"print","value":"1687-5680"},{"type":"electronic","value":"1687-5699"}],"subject":[],"published":{"date-parts":[[2018]]}}}
