Abstract: Provided is a self-position estimation mechanism that can absorb the influence of resetting of a position estimator. A difference between a position for each epoch and a position of a previous epoch estimated by a first estimation unit using a camera image and IMU information and a velocity and an acceleration for each epoch estimated by a second estimation unit using the camera image and the IMU information are acquired. Whether the difference acquired for each epoch is an outlier is tested on the basis of a threshold and whether the velocity and acceleration acquired for each epoch is an outlier is tested on the basis of a threshold. A self-position is estimated using the difference for each epoch and the velocity and acceleration for each epoch after the outlier is removed.
