| Abstract(in English) | This paper proposes a method for estimating the pose of a mobile camera by using SIFT features extracted in multiple environmental images. Corresponding points between two environmental images are detected by using SIFT-Key points, and the 3D information of the corresponding points is estimated to apply stereo vision algorithm. A data-set of landmark points is generated by combining the estimated 3D information and the appearance information (SIFT-Key). We also extract SIFT-Key points in the mobile image. The camera parameters of the mobile cameras are estimated to detect the correspondence between the data-set and the mobile camera by using SIFT-Key. Our approach has the following advantages. (1) It does not require prior knowledge of captured scene geometry or setting visual markers. (2) It is not affected by changing the appearance of the environment such as lighting condition and moving objects. |
