Vehicle recognition device

A vehicle recognition device comprising:

• an imaging unit;
• a characteristic region identifying unit which identifies two characteristic regions, which are composed of pixels having pixel values being within a predetermined range and which are arranged in a horizontal direction in an image obtained by the imaging unit;
• and
• a region outer end identifying unit which identifies outer ends in a horizontal direction of the two characteristic regions as portions in the image corresponding to both ends in a vehicle width direction of a single vehicle in the image,
• wherein the region outer end identifying unit
• includes a region width determining unit which determines whether or not a difference in width in the horizontal direction between the two characteristic regions is a predetermined value or less, and
• is configured to identify, as a corrected outer end, a border that is positioned on an inner side by the difference in the width from the outer end of a characteristic region having a larger width in the horizontal direction among the two characteristic regions in a case where the region width determining unit has determined that the difference in the width is not the predetermined value or less.
