VEHICLE EXTERIOR ENVIRONMENT RECOGNITION APPARATUS
First Claim
1. A vehicle exterior environment recognition apparatus, comprising:
- a three-dimensional object region identifier configured to identify a three-dimensional object region out of a screen, the three-dimensional object region including a three-dimensional object;
a wheel region identifier configured to identify a wheel region out of the three-dimensional object region, the wheel region including a presumed wheel that seems to correspond to a wheel of a bicycle; and
a wheel determiner configured to determine whether or not an area ratio is smaller than a predetermined value, the area ratio being a ratio of area of a segment of the wheel region to area of the wheel region, with a relative distance from the segment to an own vehicle falling within a predetermined range.

Abstract
A vehicle exterior environment recognition apparatus includes a three-dimensional object region identifier, a wheel region identifier, and a wheel determiner. The three-dimensional object region identifier is configured to identify a three-dimensional object region out of a screen. The three-dimensional object region includes a three-dimensional object. The wheel region identifier is configured to identify a wheel region out of the three-dimensional object region. The wheel region includes a presumed wheel that seems to correspond to a wheel of a bicycle. The wheel determiner is configured to determine whether or not an area ratio is smaller than a predetermined value. The area ratio is a ratio of area of a segment of the wheel region to area of the wheel region, with a relative distance from the segment to an own vehicle falling within a predetermined range.
