摘要： Example embodiments relate to using cleaning protocols to monitor defects associated with light detection and ranging (lidar) devices. An example embodiment includes a method. The method includes applying, using a cleaning device, a cleaning protocol to one or more optical components of a light detection and ranging (lidar) device. The method also includes emitting, from a light emitter of the lidar device, one or more light signals. Additionally, the method includes detecting, by a light detector of the lidar device, reflections of the one or more light signals. Further, the method includes determining, by a controller of the lidar device based on the detected reflections of the one or more light signals, that one or more defects are present within the one or more optical components or within the cleaning device.

摘要： Embodiments relate to differential methods for determining environment estimation, lidar impairment detection, and filtering. An embodiment includes dividing (502) a plurality of lidar device channels into a first group and a second group and interleaving the channels. The method involves applying (504) a threshold to a subset of the lidar channels. The lidar channels are divided into two groups: a "threshold" group and a "non-threshold" group. The group of channels that apply the threshold have less sensitivity, and are therefore less sensitive to dim returns, whereas the group of channels without the threshold maintain their sensitivity to dim returns. The slight offset in the sensitivity of the detector creates a differential in the sensitivity to the dim returns. Dim returns can be the result of fog, rain, sleet, hail, dust, haze, smog and snow, or other atmospheric scattering media.The difference in the statistical distribution between several metrics between the threshold and non-threshold channels, can be used to estimate whether or not there is an atmospheric scattering medium surrounding the vehicle. By comparing where light pulse returns are in each channel, a computing system can determine (512) the presence of an atmospheric scattering medium. By looking at the difference in the statistical distribution of several metrics between the two groups, the system could: (1) estimate medium to long range environment factors such as visibility, thus enforcing the operational driving domain; (2) estimate the hardware impairment; and (3) spatially resolve (locate) areas containing atmospheric scattering media for downstream filtering.
