Vision-based Pirouettes using the Radial Obstacle Profile

Taylor, Trevor, Geva, Shlomo, & Boles, Wageeh W. (2004) Vision-based Pirouettes using the Radial Obstacle Profile. In 2004 IEEE Conference on Robotics, Automation and Mechatronics, 1st to 3rd December, 2004, Singapore.


Mapping algorithms commonly use "radial sweeps" of the surrounding environment as input. Producing a sweep is a challenging task for a robot using only vision. With no odometers to measure turn angles, a vision-based robot must have another method to verify rotations. In this paper we propose using the Radial Obstacle Profile (ROP) which gives the radial distance to the nearest obstacle in any direction in the robot’s field of view. By matching the ROPs before and after a turn, the robot should be able to verify that the expected angle of rotation matches the actual angle. Combining successive ROPs then produces a radial sweep.

Citation counts are sourced monthly from Scopus and Web of Science® 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.
