Using Camera Tilt to Assist with Localisation
Taylor, Trevor, Geva, Shlomo, & Boles, Wageeh W. (2006) Using Camera Tilt to Assist with Localisation. In 3rd International Conference on Autonomous Robots and Agents (ICARA), 12-14 December, 2006, Palmerston North, New Zealand.
Digital cameras are often used on robots these days. One of the common limitations of these cameras is a relatively small Field of View. Consequently, the camera is usually tilted downwards in order to see the floor immediately in front of the robot. With the camera tilted, vertical edges no longer appear vertical in the image. This feature can however be used to advantage to discriminate amongst straight line edges extracted from the image when searching for landmarks. It might also be used to estimate angles of rotation and distances moved between successive images in order to assist with localisation.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
