Abstract
A method includes determining a first two-dimensional (2D) feature descriptor from a first image captured by an imaging camera in a first pose at a time of capture of the first image, the first pose including a first observation direction of the imaging camera. The method further includes storing, at an electronic device, a 3D feature descriptor including the first 2D feature descriptor and a representation of the first pose of the imaging camera. The method additionally includes determining a second 2D feature descriptor from a second image captured by the imaging camera in a second pose at a time of capture of the second image, the second pose including a second observation direction of the imaging camera. The method also includes storing the 3D feature descriptor with the second 2D feature descriptor and a representation of the second pose of the imaging camera.
