WINDOW OCCLUSION DETECTION METHOD AND APPARATUS

WIPO Patent Application WO/2022/179207

A1

A window occlusion detection method and apparatus, a computer readable medium, a chip and a terminal, which belong to the technical field of sensors, and can be used for auxiliary driving and autonomous driving. Said method comprises: acquiring a first window echo intensity and a second window echo intensity, the first window echo intensity representing a reference window echo intensity, and the second window echo intensity representing a window echo intensity at a current time (S601); acquiring detection parameters of a target point at a first time and detection parameters of the target point at a second time, the detection parameters comprising the reflectivity and/or position coordinates of the target point (S602); and acquiring window occlusion parameters according to the first window echo intensity, the second window echo intensity, the detection parameters at the first time and the detection parameters at the second time, the window occlusion parameters being used for indicating a window occlusion state (S603). Said method improves the accuracy of a lidar window occlusion detection, so as to improve the advanced driving assistance system (ADAS) capability of a terminal in autonomous driving or auxiliary driving.
