Camera position and posture estimation from image sequence can be applied to the fields of augmented reality and robot navigation. In these fields, to obtain absolute position and posture of the camera, methods using GPS and magentic sensors, and methods using input images from the camera have been investigated. However, methods using sensors are difficult to synchronize the camera and sensors accurately, and usable environments are limited according to selection of sensors. On the other hand, methods using input images of a camera needs to allocate many artificial markers otherwise an estimation error will accumulate. Thus, it is difficult to use in large and natural environments.
In this research, we propose a camera position and posture estimation method for large environments, which does not require sensors and artificial markers by detecting natural feature points from image sequence taken beforehand and using them as landmarks. |
