It has been demonstrated to be effective tackling the conflict between the increasing demands of super\u2010resolution display and the resolution limitation of a single display system. However, there is still no standardisation method for curved\u2010surface projection screen. In this study, we propose a novel approach for calibrating multi\u2010projector display systems, which have curved surfaces. First, based on a detailed analysis on arbitrarily curved surfaces, we present a three\u2010dimensional reconstruction algorithm based on Bezier surface models. Then, for fully utilising the projection area of each projector, we propose a novel curved\u2010surface stitching algorithm to achieve geometry seamlessness of multi\u2010projector display systems. Experimental results show that by constructing local Bessel models for the curved screen, the proposed method performs better than traditional approaches, i.e. the new method achieves geometric calibration with higher accuracy. The proposed method of modelling projection screen and the corresponding automatic geometric correction scheme effectively increase the utilisation ratio of the original projection area of each projector and improve the calibration accuracy of multi\u2010projector system with continuous curved surface.<\/jats:p>","DOI":"10.1049\/iet-ipr.2018.5575","type":"journal-article","created":{"date-parts":[[2019,3,28]],"date-time":"2019-03-28T22:26:28Z","timestamp":1553811988000},"page":"1050-1055","update-policy":"https:\/\/2.zoppoz.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Automatic geometry calibration for multi\u2010projector display systems with arbitrary continuous curved surfaces"],"prefix":"10.1049","volume":"13","author":[{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0003-1773-9760","authenticated-orcid":false,"given":"Xiuhui","family":"Wang","sequence":"first","affiliation":[{"name":"College of Information Engineering, China Jiliang University 258 Xueyuan Street Hangzhou People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/2.zoppoz.workers.dev:443\/https\/orcid.org\/0000-0002-1611-6636","authenticated-orcid":false,"given":"Ke","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Information Engineering, China Jiliang University 258 Xueyuan Street Hangzhou People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanqiu","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Information Engineering, China Jiliang University 258 Xueyuan Street Hangzhou People's Republic of China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2019,4,25]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2005.27"},{"key":"e_1_2_8_3_1","unstructured":"2001 Proc.
