Abstract
Various technologies described herein pertain to detecting data in a lidar point cloud representative of vapor and controlling an autonomous vehicle based on such detection. The lidar point cloud is outputted by a lidar sensor system of the autonomous vehicle. The techniques set forth herein utilize dual return lidar data outputted by the lidar sensor system. The dual return lidar data includes two lidar returns received responsive to a light beam emitted (e.g., at a particular azimuthal angle) by the lidar sensor system into a driving environment of the autonomous vehicle. The data in the lidar point cloud detected as being caused by vapor can be removed from downstream processing; accordingly, the autonomous vehicle can be controlled such that the autonomous vehicle need not stop for or maneuver around vapor in the driving environment.
