Visual compass

چکیده

We present in this paper a method to incrementally estimate the heading of a robot using panoramic images grabbed while the robot moves in its environment. We present results that show a performance similar to a magnetic compass, if not better in some cases. In particular, the heading measured by the visual compass does not drift as normal odometry does, provided the robot turns roughly by the same amount in both directions. We discuss the performance of the system as well as its limitations. We also briefly give examples of applications where the visual compass could be used and constitute an improvement.

A Visual Pathway Links Brain Structures Active during Magnetic Compass Orientation in Migratory Birds

The magnetic compass of migratory birds has been suggested to be light-dependent. Retinal cryptochrome-expressing neurons and a forebrain region, "Cluster N", show high neuronal activity when night-migratory songbirds perform magnetic compass orientation. By combining neuronal tracing with behavioral experiments leading to sensory-driven gene expression of the neuronal activity marker ZENK duri...

Fisheye-Lens-Based Visual Sun Compass for Perception of Spatial Orientation

In complex aeronautical and space engineering systems, conventional sensors used for environment perception fail to determine the orientation because of the influences of the special environments, wherein geomagnetic fields are exceptional and the Global Positioning System is unavailable. This paper presents a fisheye-lens-based visual sun compass that is efficient in determining orientation in...

Visual Compass Methods for Robot Navigation

A compass based purely on visual information would be a useful navigational tool for robots working in environments where magnetic and GPS compass information is not available. A visual compass processes a pair of panoramic images taken from two different positions and estimates the orientation change between them. We present in this paper several well known algorithms useful for the developmen...

Orientation system in Robots: Merging Allothetic and Idiothetic Estimations

For the last decade, we have developed a bioinspired control architecture for the autonomous navigation of mobile robots. The robot is able to learn to reproduce a homing or a route following behavior by interacting with a human teacher. However, the system strongly relies on the estimation of the orientation provided by a magnetic compass. We propose in this paper a model of visual compass in ...

Fast Monocular Visual Compass for a Computationally Limited Robot

This paper introduces an extremely computationally inexpensive method for estimating monocular, feature-based, heading-only visual odometry a visual compass. The method is shown to reduce the odometric uncertainty of an uncalibrated humanoid robot by 73%, while remaining robust to the presence of independently moving objects. High efficiency is achieved by exploiting the planar motion assumptio...
