Problems solved by technology

Furthermore, most modern implementations do not consider the lifetime maintenance of visual SLAM maps and cannot guarantee reliable navigation performance over the lifetime of the robot over many years
Many issues such as infinite growth of map files and extremely high computational cost of incremental map updates limit the usability of visual SLAM

Embodiment Construction

[0073] Visual positioning systems and related methods for mobile devices utilize at least one camera (optionally embodied in first and second cameras), at least one infrared illumination source, and at least one processor configured to detect infrared wavelengths. Flood IR illumination sources can be used to illuminate objects in the environment to locate mobile devices (e.g., to confirm their location), and structured IR illumination sources can be used to illuminate objects to detect and map obstacles (both static and dynamic) in the environment . Operation of the at least one infrared camera and the illumination source is coordinated by at least one processor such that the flood infrared illumination source is active during a first illumination interval and the structured infrared illumination source is active during a second illumination interval. A first infrared camera can be used in conjunction with a flood infrared illumination source for locating a mobile device in an...

Abstract

A visual positioning system for mobile devices includes at least one infrared camera, at least one infrared illumination source, and a processor that coordinates operation of the at least one camera and illumination sources. A flood IR infrared illumination source illuminates environmental objects for localization of the mobile device during a first camera exposure window, and a structured IR illumination source illuminate environmental objects for detection and mapping of obstacles during a second camera exposure window. A visual SLAM map is constructed with images obtained from a first camera, with a single map being useable for positioning and navigation across a variety of environmental lighting conditions. A method for training a robot includes receiving operator input signals configured to start and stop recording of defined routes during the guiding of the mobile robot along paths between different pairs of desired robot destinations, such that routes for subsequent use by the robot are generated for paths imaged while recording is active.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 697,520, filed July 13, 2018, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to the navigation of mobile devices, including but not limited to autonomous vehicles, mobile delivery robots, and user positioning devices such as wearables, entertainment devices, and mobility aids, and more particularly to Navigation in a modernized environment. Background technique [0004] A wide variety of automated guided vehicles (AGVs) have been used for decades to autonomously transport items in manufacturing and warehouse environments. These environments are typically constructed for use with robots (e.g., by providing machine-readable landmarks), often have little dynamic change with respect to new or unexpected obstacles, and often have consistent lighting conditions. Over ti...
