Abstract
The present disclosure relates to methods, apparatus and systems for automatically adapt the zoom coefficient of the camera of a system when running an augmented reality application. A pose estimation is performed for the camera which captures the real scene and the boundaries of the AR scene are calculated. According to the camera frustum and the boundaries, three-dimension rectangles are computes to determine a zoom coefficient that would optimize the seeing of the seen and the optimal position for the camera. The zoom is automatically optically or digitally adapted and the optimal position is indicated to the user by visual, audio or haptic means.
