A sensor degradation detection and repair system includes one or more sensors configured to collect image data from an environment. Various combinations of techniques may be used to detect degradation within a region of image data acquired by a sensor, comprising one or more of determining a level of visual consistency between associated image regions acquired by different sensors, determining a level of opacity for the image regions, and/or measuring temporal motion of image regions acquired by sensors over a period of time. Operation of a vehicle or other system may be controlled based at least in part on detection of degradation of image data acquired by a sensor, including automatically cleaning a sensor surface, reducing a level of dependence on image data received from the sensor, and/or changing a direction of travel of the vehicle.
一种传感器退化检测和修复系统包括一个或多个传感器,被配置为从环境中收集图像数据。多种技术组合可用于检测由传感器采集的图像数据区域内的退化,包括以下各项中的一项或多项:确定由不同传感器采集的相关联图像区域之间的视觉一致性水平、确定图像区域的不透明性水平和/或测量由传感器在一时间段内采集的图像区域的时间运动。车辆或其他系统的操作可以至少部分地基于对由传感器采集的图像数据退化的检测进行控制,包括自动清洁传感器表面、减少对从传感器接收的图像数据的依赖水平,和/或改变车辆的行驶方向。
