  • Stereo type vehicle monitoring apparatus with a fail-safe function
    Patent number: 6310546
    Abstract: A stereo type vehicle monitoring apparatus with a fail-safe function comprises a pair of cameras 1, 2, a stereo image producer 3, 4, 5, a calculator 12 and a fail decision unit 12. The pair of cameras 1, 2 take pictures of scenes outside of a vehicle. The stereo image producer 3, 4, 5 produces a first image and a second image respectively based on pictures; taken by the cameras 1, 2. The calculator 12 calculates a level of brightness of a first monitor area in the first image produced by the stereo image producer 3, 4, 5 and a level of brightness of a second monitor area in the second image produced by the stereo image producer 3, 4, 5. The fail decision unit 12 determines a failure of the vehicle monitoring apparatus when a difference between the brightness level of the first monitor area and the brightness level of the second monitor area exceeds a predetermined value. The second monitor area positionally corresponds to the first monitor area.
