Abstract
A three dimensional object recognition device has in-vehicle cameras capturing front images of a vehicle, a recognition section and a light shaft judgment section. The recognition section detects a three dimensional object in the front images based on a parallax generated between the front images. The light shaft judgment section detects whether a light shaft phenomenon has happened in a three dimensional object area in at least one of the front images, and judges that the detected three dimensional object is an incorrect three dimensional object caused due to the light shaft phenomenon when detecting the light shaft phenomenon at every time when the recognition section detects the three dimensional object.
