An image acquisition unit () acquires an image of an area around a mobile object as image data (). A point cloud acquisition unit () acquires depth point cloud data () representing a depth, which is a distance to an object existing in the area around the mobile object, by a point cloud. A generation unit () calculates a depth to a position represented by a pixel included in the image data (), using the image data () and the depth point cloud data (), and generates high-resolution point cloud data () in which the calculated depth is added to the pixel included in the image data (). An estimation unit () estimates a movement amount of the mobile object, using the high-resolution point cloud data ().

A direction identification unit () identifies a traveling direction in which a surrounding vehicle travels in a partial region of a region indicated by image information () obtained by photographing using a camera (). A feature amount acquisition unit () acquires a reference feature amount () being a feature amount computed from a reference image corresponding to the identified traveling direction. A vehicle determination unit () computes an image feature amount being a feature amount of the image information of the partial region and compares the computed image feature amount with the acquired reference feature amount (), thereby determining whether the surrounding vehicle is present in the partial region.

A driving support apparatus () converts at least one of a first map () and a second map () so that the first map () and the second map () become three-dimensional maps in a same coordinate system. The first map () is a three-dimensional map indicating three-dimensional positions of objects around a vehicle (). The second map () is a three-dimensional map indicating three-dimensional positions of objects around an external apparatus () that is one of a roadside apparatus () and a different vehicle () from the vehicle (). Then, the driving support apparatus () synthesizes the first map () and the second map () after the conversion, thereby generating a composite map ().

A driver assistance system according to the present invention has an other-vehicle information acquisition unit that acquires travel direction information of an other-vehicle; a storage unit in which a spot where the visibility of a driver in a vehicle is reduced and information on a direction, associated with the spot, in which the visibility of the driver of the vehicle is reduced are stored in association with each other; a visibility determination unit that determines whether or not the visibility of a driver in the other-vehicle is reduced on the basis of the travel direction information acquired by the other-vehicle information acquisition unit and the information on the direction in which the visibility is reduced stored in the storage unit; and a warning processing unit that warns a driver of an own-vehicle that the visibility of the driver in the other-vehicle is reduced if the visibility determination unit determines that the visibility of the driver in the other-vehicle is reduced.

Driver assistance system

A driving assist apparatus includes an image acquisition part to acquire a captured image around a vehicle, a position information acquisition part to acquire position information of a first object existing around the vehicle and detected by a sensor, a detection range determination part to determine a detection range of the first object within the captured image based on the position information of the first object, and an object recognition part to perform image processing on, within the captured image, an image existing in a range other than the detection range of the first object, thereby to recognize a second object that is different from the first object. Hence, a processing time taken for recognizing the second object from the captured image can be shortened.
