Abstract
The present invention includes a stereo camera for picking up a couple of images of outside a vehicle and a far-infrared sensor for detecting the temperature of an object outside the vehicle at least in a detection field overlapping a view field of the stereo camera in the vehicle-width direction. A stereo-image processing unit recognizes three-dimensional objects based on the couple of images and extracts a prospective pedestrian from the recognized three-dimensional objects. A pedestrian-determination unit determines whether or not the prospective pedestrian is a real pedestrian based on a temperature-detection value detected in the same direction the prospective pedestrian exists, where the temperature-detection value is obtained through the far-infrared sensor.
