Shape Recovery from an Image Sequence and a Gyro Sensor

Our study is the recovery of 3D shape from an image sequence. For example, your favorite building can be reconstructed and seen from a new viewpoint in a computer. In order to improve accuracy, we attached an acceleration-gyro sensor to the camera and used sensor fusion technique.
