Abstract
Official abstract text for this publication.
Visual codes are scanned to assist navigation. The visual code may be a Quick Response (QR) code that contains information useful to calibrating a variety of navigation-based sensors such as gyroscopes, e-compasses, and barometric pressure sensors.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: an imaging device; a barometric pressure sensor; and a processor coupled to the imaging device and the pressure sensor, wherein the processor causes the imaging device to scan a visual code and, based on scanning the visual code, the processor obtains a first value indicative of height of the visual code from the visual code and obtains a first barometric pressure reading from the pressure sensor, wherein, after scanning the visual…
