Abstract

The present invention relates to a mark-assisted positioning system and a method thereof, which uses a circular mark mounted to a ceiling. A full-scene image pickup device that is capable to pick up an image of 360-degree scene is employed to pick up an image of the above-located circular mark. The picked image of the mark approximates an ellipse and the major axis and the minor axis of the ellipse can be used as calculation parameters for positioning so that the current position can be obtained with triangulation. The computation process of the present invention is simple, which increases the speed of positioning. In addition, the circular mark can be detected from all directions so that interference caused by foreign objects can be avoided.
