Abstract
A field recognition apparatus includes a first camera for imaging a forward field and a second camera for imaging a road surface. The second camera has a light axis tilted toward a downward direction for accurately tracking a characteristic point in consecutively captured images to calculate an optical flow and for accurately recognizing road structure information. In this manner, three dimensional information of obstacles in a field is accurately processed and detected.
