It has three key steps i.e. (1) calibrate the camera to obtain parameters describing the spherical omnidirectional sensor, (2) map world points onto mirror points and, subsequently, onto image points, and (3) set up the projection plane for the final image unwrapping. Based on the projection plane selected, the algorithm is able to produce three common forms of unwrapping, namely cylindrical panoramic, cuboid panoramic, and ground plane view using closed form mapping equations. The motivation for developing this technique is to address the complexity in using a NSVP omnidirectional sensor and ultimately encouraging its application in robotics field. One of the main advantages of a NSVP omnidirectional sensor is that the mirror can often be obtained at a lower price as compared to the single viewpoint counterpart.<\/jats:p>","DOI":"10.1186\/1687-5281-2013-5","type":"journal-article","created":{"date-parts":[[2013,1,12]],"date-time":"2013-01-12T01:14:58Z","timestamp":1357953298000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A closed form unwrapping method for a spherical omnidirectional view sensor"],"prefix":"10.1186","volume":"2013","author":[{"given":"Nguan Soon","family":"Chong","sequence":"first","affiliation":[]},{"given":"Yau Hee","family":"Kho","sequence":"additional","affiliation":[]},{"given":"Mou Ling","family":"Dennis Wong","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2013,1,11]]},"reference":[{"key":"55_CR1","volume-title":"Patent 3505465","author":"DW Rees","year":"1970","unstructured":"Rees DW: Patent 3505465. 1970."},{"key":"55_CR2","first-page":"1029","volume-title":"Proceedings of the 1993 IEEE\/RSJ International Conference on Intelligent Robots and Systems \u201993, IROS \u201993","author":"K Yamazawa","year":"1993","unstructured":"Yamazawa K, Yagi Y, Yachida M: Omnidirectional imaging with hyperboloidal projection.
