A method for extracting keyframes from a sequence of frames for a computer vision application using structure from motion, the keyframes being a subset of representative frames from the complete sequence of frames, and an apparatus configured to perform the method are described. A subset selector selects a subset of keyframes that closely match a current camera position from already available keyframes. A determination unit then determines whether a current frame should be included a bundle adjustment keyframe set and/or a triangulation keyframe set. |
