Abstract
This disclosure describes offline navigation techniques that can precisely measure the relative offset in position and orientation (pose) between a device under test (DUT) and a reference location. Per the techniques, a unique three-dimensional (3D) label, e.g., a QR code with a small luminous sphere mounted at a small distance from the plane of the QR code, is rigidly attached to a reference location. The reference location can be a point of precisely known location and orientation, e.g., as provided by a GNSS antenna. The position and orientation of the device relative to the reference location can be calculated from images of the unique 3D label captured by a camera integrated into the DUT. Precise offline navigation, as described herein, can find use in augmented reality, extended reality and/or virtual reality (AR/XR/VR) applications, robotics, device testing, etc.
