FIELD: physics.
SUBSTANCE: device includes: image converting tool to convert the image viewpoint obtained by the image capturing means to create an image of the "bird's eye view" type; means for detecting three-dimensional objects to generate the signal type information data in the direction of vehicle width by counting, along the vehicle width direction, the number of pixels, which indicate the predetermined difference in the difference image, wherein the positions of the "bird's eye view" image type are combined, and shot at different time periods, and generating a frequency distribution and processing, based on the signal type information in the vehicle width direction, the detection in the vehicle width direction, in which the three-dimensional objects are detected, that are present in the detection area; a means of assessing the three-dimensional objects to assess whether or not the detected three-dimensional object is another vehicle.
EFFECT: evaluation of the detected three-dimensional objects.
