Abstract: Embodiments of the present disclosure are directed to providing a more accurate presentation of a vehicle's surroundings when the presentation combines images from multiple cameras. Cameras may capture the same portion of the environment. If an object is within view of at least two cameras, each camera produces a portion of an overall view, such as a 360 degree synthetic top-down view. The seam, angle and/or geometry, angle between any two images is dynamically determined, such as due to proximity (or lack thereof) to an object. As a result the synthetic top-down view may present an image of an object more prominently and/or avoid having the seam between camera images fall on the image of the object, which may otherwise result in the image of the object being omitted from both camera images.

Abstract: Embodiments of the present disclosure are directed to providing an Augmented Reality (AR) navigation display in a vehicle.

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.
