Abstract: PURPOSE: An apparatus and a method for real-time camera tracking for a large map are provided to prevent the shortage of a memory resulting from the increase of input data even in the broad movement of a camera by predicting the position and rotation of the camera from an inputted image in real time. CONSTITUTION: A global camera tracking unit(12) performs non-real time calculation for a global specific point map(14), and a local camera tracing unit(13) performs real time calculation for a local specific point map. A global specific point map updater updates the information of the feature point map by the feature information. A local specific point map selector(11) selects specific points within the local feature point map based on the update information.
