Abstract
Embodiments of the present disclosure are directed to providing an Augmented Reality (AR) navigation display in a vehicle. More specifically, embodiments are directed to rendering AR indications of a navigation route over a camera video stream in perspective. According to one embodiment, visual tracking can be performed on features in the video data and camera pose, i.e., a matrix encapsulating position and orientation, can be determined for each frame of video based on both the visual tracking and navigation sensor data. These separately determined camera poses can then be merged or fused into a single camera pose that is more accurate and more stable and which can then be used in rendering more realistic AR route indicators onto the video of the real-world route captured by the camera.
