Abstract
A method for detecting a displacement of a mobile platform is provided. The method includes acquiring a first frame and a second frame using an imaging device that is coupled to the mobile platform, and obtaining rotation data using an inertial measurement unit (IMU) that is coupled to the mobile platform. The method also includes calculating a translation array based on the first frame, the second frame, and the rotation data. The method further includes determining the displacement of the mobile platform based on the translation array.
