Abstract

A system includes one or more hardware processors, a head mounted display (HMD), a digital camera device, and a path extraction engine. The path extraction engine is configured to receive two-dimensional (2D) video from the digital camera device, the 2D video presenting a 2D view of a three-dimensional (3D) object, the digital camera device moving along a camera path as the digital camera device captures the 2D video, identify a plurality of 2D features associated with the 3D object within the 2D video, track the plurality of 2D features across multiple frames of the 2D video, estimate motion in pixels associated with each 2D feature of the plurality of 2D features, using the estimated motion in the pixels, identify 2D motion caused by the digital camera device moving along the camera path, and compute a first camera position of the digital camera device based on the identified 2D motion.
