    Abstract: Apparatuses and methods for fast visual simultaneous localization and mapping are described. In one embodiment, a three-dimensional (3D) target is initialized immediately from a first reference image and prior to processing a subsequent image. In one embodiment, one or more subsequent reference images are processed, and the 3D target is tracked in six degrees of freedom. In one embodiment, the 3D target is refined based on the processed the one or more subsequent images.

    Abstract: Methods, systems, computer-readable media, and apparatuses for calibrating an event-based camera are presented. One example method includes the steps of receiving a calibration image comprising intensity information for a set of image elements defining the calibration image; iteratively, until a threshold number of different image elements have been projected: selecting a portion of the calibration image corresponding to a subset of image elements of the set of image elements, the subset comprising less than all image elements in the set of image elements, and comprising at least one image element not previously selected; projecting the selected portion of the calibration image onto a sensor of the event-based camera; detecting, by the sensor, the selected portion of the calibration image; generating a set of detected pixels corresponding to the detecting; and discontinuing projection of the selected portion; and determining, for a position of the event-based camera, at least one calibration parameter using the generated sets of detected pixels.

    Abstract: Disclosed are a system, apparatus, and method for monocular visual simultaneous localization and mapping that handles general 6DOF and panorama camera movements. A 3D map of an environment containing features with finite or infinite depth observed in regular or panorama keyframes is received. The camera is tracked in 6DOF from finite, infinite, or mixed feature sets. Upon detection of a panorama camera movement towards unmapped scene regions, a reference panorama keyframe with infinite features is created and inserted into the 3D map. When panoramic camera movement extends toward unmapped scene regions, the reference keyframe is extended with further dependent panorama keyframes. Panorama keyframes are robustly localized in 6DOF with respect to finite 3D map features. Localized panorama keyframes contain 2D observations of infinite map features that are matched with 2D observations in other localized keyframes. 2D-2D correspondences are triangulated, resulting in new finite 3D map features.
