Abstract
In order to detect and avoid the obstacle, it is necessary for us to get the distance information in real-time. We have been investigating the distance estimation method using binocular camera with different focal position for each image sensor. This method estimates more precise distance by combining the information of multiple blur due to different focal positions and parallax information by binocular camera. In this paper, we implement the method on the camera system and evaluate the estimation accuracy from the perspective of the changes in the object size and the blur variation between images.
