Marker less planar textured geometric object monitoring method for e.g. virtual visit of museum, involves receiving image of video flow, and evaluating position and orientation of object to be monitored in image from key frame

摘要

The method involves receiving an image of a video flow, where the image includes an object to be monitored. A position and orientation of the object are determined from previously determined image blocks. Each image block is associated to location of the object. Another image of the video flow is received. A position and orientation of another object to be monitored in the latter image are evaluated from a key frame. The key frame represents the former image, position and orientation of the former object. Independent claims are also included for the following: (1) a computer program comprising instructions for implementing a geometric object monitoring method (2) an information storage medium comprising computer program code instructions for implementing the geometric object monitoring method (3) a device for monitoring a geometric object of a real scene.
