METHOD FOR IDENTIFYING SOILING ON A TRANSPARENT SCREEN

摘要

Camera for identifying soiling on a protective screen. The camera is focused on a scene behind the protective screen and can be used to identify soiling and for other applications, e.g. to identify driving lanes and/or to identify objects. Soiling is identified merely by evaluating frames recorded in succession, and artificial reference frames or reference objects are not required. A prerequisite for a successful measurement is that the relative speed v_rel of the camera and at least one recorded object in the surroundings is not equal to zero and its trajectory is predicted in the depiction. By comparing the relevant frame sections, possible soiling on subregions of the protective screen is identified.
