Abstract:
Camera or object pose calculation is described, for example, to relocalize a mobile camera (such as on a smart phone) in a known environment or to compute the pose of an object moving relative to a fixed camera. The pose information is useful for robotics, augmented reality, navigation and other applications. In various embodiments where camera pose is calculated, a trained machine learning system associates image elements from an image of a scene, with points in the scene's 3D world coordinate frame. In examples where the camera is fixed and the pose of an object is to be calculated, the trained machine learning system associates image elements from an image of the object with points in an object coordinate frame. In examples, the image elements may be noisy and incomplete and a pose inference engine calculates an accurate estimate of the pose.

Claim (Index 7):
A method as claimed in  claim 1  where the machine learning system comprises a plurality of trained random forests and the method comprises applying the image elements of the at least one image to the plurality of trained random forests, each random forest having been trained using images from a different one of a plurality of scenes, and calculating which of the scenes the mobile camera was in when the at least one image was captured.
