Abstract
本发明实施例提供了一种测距装置的异常检测方法、报警方法、测距装置及可移动平台。所述异常检测方法包括沿光路出射光脉冲信号；检测接收到的沿所述光路的回波信号；基于所述回波信号探测环境中的物体；获取所述回波信号中的检测信号的特征，所述检测信号包括所述光脉冲信号经所述测距装置中的元件和/或所述测距装置的检测盲区内的物体所反射的光信号；比较所述检测信号的特征与检测信号的预设特征；根据比较结果检测所述测距装置的异常。本发明实施例可以对测距装置的诸如光学器件脏污、光学窗口遮挡、功率异常增大或减小等异常进行有效的检测，并且在确定有异常时进行报警，从而为测距装置提供有效的预警机制，避免出现性能恶化甚至功能缺失。
