Abstract
A map creation apparatus includes an image receiver configured to receive images in time series while moving; a first calculator configured to extract an image area indicating an object from the images and calculate a coordinate of the object in a world coordinate system; a second calculator configured to track the object in the extracted image area with the images and calculate an optical flow of the object; an eliminator configured to calculate a difference in coordinate between vanishing points generated by the movement of the image receiver and the object based on the optical flow, and eliminate the image area of the object from the images when determining the object as a moving object based on the calculated difference; and a storage controller configured to store map information including the coordinate of the object, not eliminated by the moving object eliminator, in the world coordinate system.
