Abstract / Hauptanspruch
A configuration is achieved that calculates an object distance on the basis of a captured image of a camera that captures an image in a direction that is orthogonal to a movement direction of a movement device or in a direction having an orthogonal component. A data processing unit detects a point at infinity from a captured image of a camera that captures an image in a direction that is orthogonal to a movement direction of a movement device or in a direction having an orthogonal component, and calculates an object distance by using information relating to a positional relationship between a position of the detected point at infinity and a position of an object in the captured image. The data processing unit detects, from the captured image, a plurality of parallel lines on a real world that extends in a direction away from a camera position, and determines an intersection point on extended lines of the detected plurality of parallel lines to be the point at infinity. Alternatively, an intersection point on respective extended lines of the straight lines in an image frame unit is determined to be the point at infinity, directions of the straight lines changing on the captured image in accordance with a movement of the camera.
