Visual localization and loop-back detection with a high resolution omnidirectional camera
ثبت نشده
چکیده
We present an application in topological map building and localization with a high resolution omnidirectional camera. A visual map uses sift features in combination with affinely invariant Harris corners as its feature points. We use an automatic scheme to find correspondences from a video sequence to create the map. Loop-back is also detected automatically while the map is built. For localization, we use a vote transfer technique that uses prior knowledge about correspondences within the map to localize a query image instead of a majority vote.

متن کاملFast Learnable Object Tracking and Detection in High-resolution Omnidirectional Images
This paper addresses object detection and tracking in high-resolution omnidirectional images. The foreseen application is a visual subsystem of a rescue robot equipped with an omnidirectional camera, which demands real time efficiency and robustness against changing viewpoint. Object detectors typically do not guarantee specific frame rate. The detection time may vastly depend on a scene comple...
متن کاملDiagnostic Accuracy of Digitized Images Using Different Resolution Settings of Digital Camera in Detection of Proximal Caries
Objective: When none of digital systems and scanners is accessible and it is essential to have digitized images of conventional radiographs, digital cameras can be used. The Aim of this study was to investigate whether digital images obtained by different resolutions of a digital camera are matched to the original radiographs in evaluation of caries. Methods: In this diagnostic accuracy in v...
متن کاملObstacle Avoidance with Simultaneous Translational and Rotational Motion Control for Autonomous Mobile Robot
This paper describes an approach to the Simultaneous Localization and Mapping (SLAM) problem using a single omnidirectional camera. We consider that the robot is equipped with a catadioptric sensor and is able to extract interest points from the images. In the approach, the map is represented by a set of omnidirectional images and their positions. Each omnidirectional image has a set of interes...
متن کاملClosing the Loop in Appearance-Guided Structure-from-Motion for Omnidirectional Cameras
In this paper, we present a method that allows us to recover a 400 meter trajectory purely from monocular omnidirectional images very accurately. The method uses a novel combination of appearance-guided structure from motion and loop closing. The appearance-guided monocular structure-from-motion scheme is used for initial motion estimation. Appearance information is used to correct the rotation...
