Abstract: Systems, apparatus and methods to create a database by a device (such as a server) and to use the database by a mobile device for detecting a planar target are presented. The database allows recognition of a planar target by a mobile device from steeper angles with minimum impact on runtime. The database is created from at least one warped view of the planar target. For example, a database may contain keypoints and descriptors from a non-warped view and also from one or more warped views. The database may be pruned by removing keypoints and corresponding descriptors of one image (e.g., a warped image) overlapping with similar or identical keypoints and descriptors of another image (e.g., a non-warped image).

Abstract: A computer-implemented method of tracking a target object in an object recognition system includes acquiring a plurality of images with a camera. The method further includes simultaneously tracking the target object and dynamically building environment map data from the plurality of images. The tracking of the target object includes attempting to estimate a target pose of the target object with respect to the camera based on at least one of the plurality of images and based on target map data.

If not, then the method includes inferring the target pose with respect to the camera based on the dynamically built environment map data. In one aspect the method includes fusing the inferred target pose with the actual target pose even if tracking is successful to improve robustness.

If a repeatability of the selected feature is greater than a repeatability threshold and if a discriminability is greater than a discriminability threshold, then at least one derived feature is stored to the database, where the derived single feature is representative of the second set of features.
