Abstract: A moving object detection device includes: an image capturing unit with which a vehicle is equipped, and which is configured to obtain a captured image by capturing a view in a travel direction of the vehicle; a calculation unit configured to calculate, for each of first regions which are unit regions of the captured image, a first motion vector indicating movement of an image in the first region; an estimation unit configured to estimate, for each of one or more second regions which are unit regions each including first regions, a second motion vector using first motion vectors, the second motion vector indicating movement of a stationary object which has occurred in the captured image due to the vehicle traveling; and a detection unit configured to detect a moving object present in the travel direction, based on a difference between a first motion vector and a second motion vector.

Abstract: A moving object detection device includes: an image capturing unit with which a vehicle is equipped, and which is configured to obtain captured images by capturing views in a travel direction of the vehicle; a setting unit configured to set, for each of frames that are the captured images, a movement vanishing point at which movement of a stationary object in the captured images due to the vehicle traveling does not occur; a calculation unit configured to calculate, for each of unit regions of the captured images, a first motion vector indicating movement of an image in the unit region; and a detection unit configured to detect a moving object present in the travel direction, based on the movement vanishing points set by the setting unit and the first motion vectors calculated by the calculation unit.
