ABSTRACT:
A method and apparatus for observing vehicles on a road or in a parking lot comprises a pair of cameras directed toward a predetermined observation position simultaneously take pictures. A characteristic portion in each of the respective pictures is extracted. The extracted characteristic portions of the respective pictures are corresponded to the pictures, and the corresponded characteristic portion is measured in three-dimensions to extract the three-dimensional coordinates of the characteristic portions. The three-dimensional coordinates of the extracted characteristic portions are projected on a virtual perpendicular plane, and the projected data is compared with pre-determined two dimensional model data to discriminate the object.
