The use of fish-eye lenses allows the master camera to maximize the coverage area while the PTZ acts as a foveal sensor, providing high-resolution images of regions of interest. Despite the advantages of this architecture, the mapping between image coordinates and pan-tilt values is the major bottleneck in such systems, since it depends on depth information and fish-eye effect correction. In this paper, we address these problems by exploiting geometric cues to perform height estimation. This information is used both for inferring 3D information from a single static camera deployed on an arbitrary position and for determining lens parameters to remove fish-eye distortion. When compared with the previous approaches, our method has the following advantages: (1) fish-eye distortion is corrected without relying on calibration patterns; (2) 3D information is inferred from a single static camera disposed on an arbitrary location of the scene.<\/jats:p>","DOI":"10.1155\/2015\/427270","type":"journal-article","created":{"date-parts":[[2015,9,20]],"date-time":"2015-09-20T21:01:56Z","timestamp":1442782916000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["A Master-Slave Calibration Algorithm with Fish-Eye Correction"],"prefix":"10.1155","volume":"2015","author":[{"given":"J.
