Original Abstract Submitted
A vanishing point calculator includes a controller connected to an imaging device configured to image in a vehicle traveling direction; and a storage device connected to the controller, wherein the controller is configured to: input an image imaged by the imaging device; extract positions of feature points from the image; store the positions of feature points related to a stationary object including a line segment parallel to road among the extracted feature points in the storage device for each image; overlap the feature points in a predetermined number of the images stored in the storage device based on the positions of the feature points; and calculate the position of vanishing point in the image imaged by the imaging device based on a line segment obtained by the overlapped feature points.
