AUGMENTED REALITY METHOD AND DEVICES USING A REAL TIME AUTOMATIC TRACKING OF MARKER-FREE TEXTURED PLANAR GEOMETRICAL OBJECTS IN A VIDEO STREAM

摘要

The present invention is an actual scene in the at least two images of the video stream for the application of Augmented Reality or a plurality of substantially planar geometric objects for the purpose of the method and apparatus for tracking in real time. A first image of the video stream including the tracking target object is received (300), then the position and orientation of the object within the first image is determined from a plurality of image blocks (320) determined in advance, the plurality Each block of the image block is associated in the pose of the tracked object. Position and orientation of the tracking target object in the first image and the first image in the form the key (key) image. In the second image received in the video stream, the position and orientation of the second object in the tracking of the target in the image is calculated from the key images (330). Is the position and orientation of the object in the second image and the tracking object is stored as a key image. If the position and orientation of the tracking target object is found from the key image in the second image, the position and orientation of the tracking target object in the image is given in the second plurality of image blocks, and relevant be exported (exposure) is determined from.
