Wide-Angle Visual Feature Matching for Outdoor Robot Navigation

We describe an outdoor mobile robot navigation and localisation system based on a new visual feature detector designed for wide-angle image sequences. Wide-angle images exhibit significant radial distortion for which existing scale-space detectors such as SIFT are inappropriate. We argue that the required scale-space images can be correctly obtained through the convolution of the image, mapped ...

An Asymmetrical Probabilistic Estimation using Structural Matching for Outdoor Localization ⋆

Location-Based Services (LBSs) for mobile communication are widely used in which location estimation is the prerequisite. We propose an Asymmetrical Probabilistic Estimation (APE) method based on the location fingerprinting. In proposed method, the signal intensity variations for each cell in each fingerprint are modeled by Gaussian distributions with asymmetrical probability density function d...

A Novel Feature Extraction Algorithm for Outdoor Mobile Robot Localization

Navigation is one of the basic problems for autonomous mobile robots. Its history can be traced back to long time ago. Today, navigation is a well-understood quantitative science, used routinely in maritime and aviation applications [Adams, 1999]. Given this, the question must be asked as to why robust and reliable autonomous mobile robot navigation remains such a difficult problem. The core of...

Wide-Angle Intraocular Imaging and Localization

Vitreoretinal surgeries require accuracy and dexterity that is often beyond the capabilities of human surgeons. Untethered robotic devices that can achieve the desired precision have been proposed, and localization information is required for their control. Since the interior of the human eye is externally observable, vision can be used for their localization. In this paper we examine the effec...

Binary Feature Based Localization for Visual Odometry

Recently, Google, Microsoft and several start-ups have started to launch services for indoor maps. Due to its potentially high localization accuracy and its independence from hardware installations, visual indoor localization and navigation for hand-held devices is becoming a hot topic. A visual localization system consists of a visual odometry system with an integrated relocalization algorithm...
