摘要： A method for recognizing a blockage of a lidar system of a vehicle. The lidar system scans an environment with several laser receiver systems in a shared field of vision. An object point cloud is identified which is created by reflection of laser beams of the laser receiver systems on a surface of an object located in the shared field of vision. It is determined whether points of the identified object point cloud originate from the laser beams of all of the laser receiver systems of the lidar system and substantially have the same intensities. It is concluded that the lidar system is blocked if the points do not originate from the laser beams of all of the laser receiver systems, or if the points originate from the laser beams of all of the laser receiver systems, but do not substantially have the same intensities.

摘要： This application discloses a LiDAR, a mobile device, and a LiDAR attachment detection method, where the LiDAR includes a transceiving assembly, a window, a detection module, and a control module. The transceiving assembly is configured to emit an outgoing beam and receive an echo beam. The window is mounted on an optical path corresponding to the transceiving assembly, where part of the outgoing beam emitted by the transceiving assembly forms a reflected beam after being reflected by the window, and the reflected beam includes a specular reflected beam. The detection module is configured to receive the reflected beam and generate a corresponding electrical signal. The control module is electrically connected to the transceiving assembly and the detection module, where the control module is configured to determine whether there is an attachment on the window based on the corresponding electrical signal.

摘要： A method for checking a functional capability of a distance sensor of a vehicle includes continuously receiving sensor data from the distance sensor, wherein the sensor data describe a sensor signal emitted by the distance sensor and reflected on at least one object in an environment of the vehicle; continuously determining distance values, which describe a distance between the distance sensor and the at least one object, on the basis of the sensor data; storing the distance values for a predetermined period of time; determining a current range of the distance sensor on the basis of the stored distance values; comparing the current range with a predetermined maximum range of the distance sensor; and checking the functional capability of the distance sensor on the basis of the comparison.

摘要： The technology relates to detecting water or fouling on the exterior surface of a sensor cover, for instance due to precipitation or debris (fouling). Such objects on the sensor cover surface may degrade operation of the sensor, which can be problematic for vehicles operating in an autonomous driving mode. According to an aspect of the technology, a waveguide layer is provided on the sensor cover. A laser emits light at a selected wavelength along one side of the waveguide layer. The light waveform propagating along the waveguide layer is affected (distorted) by precipitation and/or fouling on the surface of this layer. A detector receives the distorted waveform. The system determines whether water and/or fouling is present based on the received waveform. This allows the system to determine whether to activate a cleaning module or to factor in the information when processing received sensor data.

摘要： A method determines a blockage of a sensor of a plurality of sensors of an ego vehicle. The method determines a prior blockage probability of the sensor of the plurality of sensors; receives sensor data of the sensor of the plurality of sensors; determines a performance of the sensor based on the received sensor data; calculates a posterior blockage probability based on the prior blockage probability of the sensor and the performance of the sensor; and determines the blockage of the sensors using the calculated posterior blockage probability.

摘要： In one embodiment, a method for dynamically varying receiver characteristics in a lidar system includes emitting light pulses by a light source in a lidar system. The method further includes detecting, by a receiver in the lidar system, light from one of the light pulses scattered by one or more remote targets to identify a return light pulse. The method also includes determining an atmospheric condition at or near a geolocation of a vehicle that includes the lidar system. The method further includes providing a control signal to the receiver adjusting one or more characteristics of the receiver to compensate for attenuation or distortion of the return light pulses associated with the atmospheric condition.

摘要： The present disclosure relates to optical systems and methods of their operation. An example optical system includes an optical component and one or more light sources configured to emit a light signal. The light signal interacts with the optical component so as to provide an interaction light signal. The optical system also includes a detector configured to detect at least a portion of the interaction light signal as a detected light signal. The optical system additionally includes a controller configured to carry out operations including causing the one or more light sources to emit the light signal and receiving the detected light signal from the detector. The operations also include determining, based on the detected light signal, that one or more defects are associated with the optical component.
