Title: | A Fast Firing Binaural System for Ultrasonic Pattern Recognition | Authors: | Moita, Fernando Lopes, Ana Nunes, Urbano |
Issue Date: | 2007 | Citation: | Journal of Intelligent and Robotic Systems. 50:2 (2007) 141-162 | Abstract: | Abstract A binaural sonar configuration with capability to detect and identify walls, edges and corners on real-time is presented in this work. A new multi-echo ultra-fast firing method increases the sonar acquisition rate, and provides crossed measurements without interference. A feature map is built on-line using Bayesian updating and classification rules. Three classifiers are implemented and analyzed: minimum risk (MR), maximum a posteriori (MAP), and minimum distance (MD). Experimental results of ultrasonic reflector recognition, using data collected in a specular indoor environment are presented in the paper. | URI: | https://hdl.handle.net/10316/7630 | DOI: | 10.1007/s10846-007-9158-5 | Rights: | openAccess |
