Abstract:
    This invention discloses one method to test outdoor water obstacle based on bias phase, which comprises the following steps: before cameral fixing bias filter lens and collecting different bias phase images in same one area; computing the bias vibration phase image and similar test image and to judge water obstacle existence within regression similarity image and then dividing water obstacle range through grey valve values. This invention can test integral water surface area through reflection bias vibration property with good identification effect.
