Abstract
A head-mounted display device includes a camera, an inertial sensor in a first spatial relationship with the camera, and a processor that: acquires an image data sequence from the camera; and acquires a sensor data sequence from the inertial sensor; derives a first pose of an object based at least on one of image frames in the image data sequence and template data created based on a 3D model corresponding to the object; derives a second spatial relationship between an object coordinate system defined on the object or the 3D model and a global coordinate system based at least on the first pose or a pose tracked from the first pose, the sensor data sequence and the first spatial relationship; and derives a second pose of the object based at least on the image data sequence, the sensor data sequence and the second spatial relationship using a non-linear estimation algorithm.
