This article presents algorithms that determine the true position of a mobile robot, based on real 2-D and 3-D optical range and inten sity data. We start with the physics of the particular type of sensor used, so that the extraction of reliable and repeatable information (namely, edge coordinates) can be determined, taking into account the noise associated with each range sample and the possibility of optical multiple-path effects. Again, applying the physical model of the sensor, the estimated positions of the mobile robot and the uncertainty in these positions are determined. We demonstrate real experiments using 2-D and 3-D scan data taken in indoor environ ments. To update the robot's position reliably, we address the prob lem of matching the information recorded in a scan to, first, an a priori map, and second, to information recorded in previous scans, eliminating the need for an a priori map.<\/jats:p>","DOI":"10.1177\/027836499801700901","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T03:05:13Z","timestamp":1173582313000},"page":"907-923","source":"Crossref","is-referenced-by-count":24,"title":["Tracking Naturally Occurring Indoor Features in 2-D and 3-D with Lidar Range\/ Amplitude Data"],"prefix":"10.1177","volume":"17","author":[{"given":"M.D.","family":"Adams","sequence":"first","affiliation":[{"name":"Institute of Robotics Swiss Federal Institute of Technology Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Kerstens","sequence":"additional","affiliation":[{"name":"Institute of Robotics Swiss Federal Institute of Technology Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,9,1]]},"reference":[{"key":"atypb1","volume-title":"Optical range data analysis for stable target pursuit in mobile robotics.
