The invention provides a smudginess detection method and device and a smudginess cleaning method and device for a laser radar light window, and relates to the technical field of laser radar detection. According to the specific implementation scheme, laser beams are emitted; receiving an echo signal generated by the laser beam; and determining dirt levels corresponding to different areas of the laser radar light window based on the pulse width of the echo signal. Graded early warning is carried out on different smudginess degrees of the laser radar light window, the smudginess area can be accurately positioned, the detection precision is improved, a vehicle cleaning system is guided to carry out targeted cleaning, and the overall safety performance of an automatic driving system is improved.

    本公开提供了一种激光雷达光窗的脏污检测方法及装置、清理方法及装置,涉及激光雷达检测技术领域。具体实现方案为:发射激光光束;接收到激光光束产生的回波信号;基于回波信号的脉宽确定激光雷达光窗不同区域对应的脏污等级。本公开通过对激光雷达光窗的不同脏污程度进行分级预警,并且可以精确定位脏污区域,提高检测精度,指导车辆清洁系统进行针对性地清理,提升自动驾驶系统的整体安全性能。
