  • Patent number: 8155380
    Abstract: A method and apparatus for recognizing obstacles in an environment about a motorized vehicle moving along a roadway is presented. The apparatus includes an optical sensor and a data processing device. A method using the apparatus includes taking images with the optical sensor which contains at least a first and a second image. The first and the second image are each transformed above and below a plane as viewed by the optical sensor to further determine upper and lower difference images by the data processing device. The data processing device further determines whether an obstacle is located in the travel path of the vehicle by evaluation of the lower and upper difference images.
