Detection of planar target of the original steep angle

摘要

(such as a server) in order to create a database by the device, and the system for the use of the database by the mobile device in order to detect the plane target, the presentation device, and methods. The database while minimizing the impact on run-time, allowing the recognition of the planar target by the mobile device from the steeper. The database is created from at least one warped view of the planar target. For example, the database, from the view is not warped, and can also include key points and descriptors from one or more warped views. One of the image (for example, the warped image) Among the key points and the corresponding descriptor of, overlaps with similar or the same key points and descriptors of another image (for example, an image that has not been warped) by removing the key points and corresponding descriptors, it can be pruned database.
