Abstract
A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.
