Patent Images

1. An apparatus of detecting an object on a road surface comprising:

  • a stereo set of video cameras mounted on a vehicle to produce right and left images on a road surface;

    an image storage unit configured to store the right and left images;

    a parameter computation unit configured to compute a parameter representing road planarity constraint based on the images stored in the image storage unit;

    a corresponding point computation unit configured to compute correspondence between a first point on one image of the right and left images on the road surface and a second point on other image of the right and left images, which corresponds to the first point, based on the parameter;

    an image transformation unit configured to produce a transformed image from the one image using the correspondence; and

    a detector to detect an object having a dimension larger than a given value in a substantially vertical direction with respect to the road surface, using the correspondence and the transformed image.
