摘要
A method and apparatus detects adverse weather conditions. The method provides a system including a LIDAR sensor having a transmitting portion including a light source and illumination optics, and a receiving portion having a photodetector or photodetector array for receiving reflected light, and receiving optics. The receiving optics is spaced from the illumination optics. The illumination optics and the receiving optics each define a field of view, with the field of views overlapping at a certain distance from the sensor defining a solid object sensing region. A region located outside of the solid object sensing region defines a non-overlapping region. The photodetector determines if a signal exists in the solid object sensing region indicative of a solid object therein. The same photodetector also determines if a signal exists in the non-overlapping region indicative of an adverse weather condition affecting the vehicle.
