Abstract:
A system and a method provide an orientation of a camera on a mobile device. This information can be used in an augmented reality application. The method comprises obtaining an orientation measurement from a sensor relative to the orientation of the sensor. The sensor may have different orientation compared to the camera and, thus, the orientation measurement needs to be adjusted. An appropriate transformation matrix is obtained, which maps the orientation measurement to the camera's perspective. A processor of the mobile device computes the orientation of the camera using the orientation measurement and the transformation matrix.
