Title:
MINIATURE VISION-INERTIAL NAVIGATION SYSTEM WITH EXTENDED DYNAMIC RANGE
Document Type and Number:
WIPO Patent Application WO/2017/218213
Kind Code:
A3
Abstract:
A system and method for tracking positions of objects in an actual scene in a wide range of lighting conditions. A vision-inertial navigation system is provided that may be configured to track relative positions of objects of interest in lighting conditions ranging from, e.g., typical indoor lighting conditions to direct sunlight to caves with virtually with no light. The navigation system may include two or more helmet-mounted cameras each configured to capture images of the actual scene in a different lighting condition. A remote processing element may combine data from the two or more helmet-mounted cameras with data from a helmet-mounted inertial sensor to estimate the position (e.g., 3D location) of the objects. The navigation system may display the estimated position for each object on a transparent display device such that, from a user's perspective, the estimated position for each object is superimposed onto the corresponding object and/or other information relating to the user's and/or object's position is displayed.
