ABSTRACT:
A panoramic camera is configured to automatically determine parameters of a table upon which the camera is situated as well as positional information of the camera relative to the table. In an initialization stage, table edges are detected to create an edge map. A Hough transformation-like symmetry voting operation is performed to clean up the edge map and to determine camera offset, camera orientation and camera tilt. The table is then fit to a table model to determine table parameters. In an operational stage, table edges are detected to create an edge map and the table model is fit to the edge map. The output can then be used for further panoramic image processing such as head size normalization, zooming, compensation for camera movement, etc.
