Abstract
Techniques for identifying false-positive sensor observations include using sensor observations from different sensor modalities. The techniques may include receiving first sensor data (e.g., radar data) and second sensor data (e.g., lidar data) generated by different types of sensors of a vehicle that is operating in an environment. The techniques may also include determining an absence of an observation in the first sensor data at a location in the environment where an observation is indicated in the second sensor data. The techniques may also include receiving an indication that a retroreflective surface is present in the environment. Based at least in part on at least one of the retroreflective surface being present in the environment or the absence of a radar observation at the location in the environment where a lidar observation is indicated, the techniques may include determining that the observation in the second sensor data is a false-positive observation.
