Dynamic Omnidirectional Vision Localization Using a Beacon Tracker Based on Particle Filter

Vision Based Obstacle Detection Module for a Wheeled Mobile Robot

“…It was used Hue, Saturation, and Intensity (HSI) color since it is perceptually uniform. In (Cao, 2001) was presented an omnidirectional vision camera system that produces spherical field of view of an environment, the continuation of this work was presented in (Cao et al, 2008) where the authors explained several important issues to consider for using fisheye lens in omnidirectional vision, some of them are the lens camera calibration, rectification of the lens distortion, the use of a particle filter for tracking, as well as the algorithms and the hardware configuration that they implemented. Recently, the company "Mobile Robots" announced a heavy duty high speed stereoscopic vision system for robots called "MobileRanger StereoVision System", that is able to provide processed images at a maximal rate of 60 fps (frames per second) with a resolution of 752 × 480 pixels.…”

Efficient Stereoscopic Video Matching and Map Reconstruction for a Wheeled Mobile Robot

“…Hue, Saturation and Intensity (HSI) colour were used since it is perceptually uniform.
