Route representation for mobile robot navigation by omnidirectional route panorama Fourier transformation
Yasushi Yagi, Shigeto FUJIMURA, M. Yachida · 2002
Described here is a route navigation method for a mobile robot with an omnidirectional image sensor. The route is memorized by a series of two dimensional Fourier power spectra of consecutive omnidirectional images at the horizon while the robot moves to the goal position. While the robot is navigating to the goal point, it is controlled by comparing the principal axis of inertia of its current position with that of the memorized Fourier power spectrum.
