Abstract
A method may include the following steps: acquiring, from a camera, an image frame; acquiring, from an inertial sensor, a sensor data sequence; tracking a first pose of an object in a real scene based at least on the image frame; deriving a sensor pose of an inertial sensor based on the sensor data sequence; determining whether the first pose is lost; retrieving from one or more memories, or generating from a 3D model stored in one or more memories, a training template corresponding to a view that is based on the sensor pose obtained on or after the first pose is lost; and deriving a second pose of the object using the training template.
