Method for a vehicle to detect a phenomenon affecting visibility

摘要

The method involves emitting a light beam e.g. infrared beam, generated by an LED, in a vision field of a video camera of a vehicle. Presence and nature of a visibility disruptive phenomenon i.e. spray of water, are determined from an image acquired by the camera by a control unit. The nature of the visibility disruptive phenomenon is determined by the control unit based on the homogeneity of the visibility disruptive phenomenon on the image. Independent claims are also included for the following: (1) a visibility disruptive phenomenon detecting device comprising a control unit (2) a computer program product having set of instructions to execute a visibility disruptive phenomenon detecting method.
