Abstract
Embodiments of the present disclosure are directed to an augmented reality based user's manual for a vehicle implemented as an application on a mobile device which allows the user to point a mobile phone, tablet or an augmented reality headset at any part of the vehicle interior or exterior and experience augmented annotations, overlays, popups, etc. displayed on images of real parts of the car captured by the user's mobile device. Embodiments provide for estimating the camera pose in six degrees of freedom based on the content of the captured image or video and using a neural network trained on a dense sampling of a three-dimensional model of the car rendered with realistic textures to identify and properly align the augmented reality presentation with the image of the vehicle being captured by the mobile device.
