Abstract
An imaging system is described for generating an estimate for a virtual horizon for a moving vehicle. The estimate is based on a lidar point cloud and on pitch rate data from a gyroscope. The lidar point cloud data estimates the horizon based on lidar scans that are updated at a first rate. The gyroscope data is updated at a second rate that is faster than the first rate and therefore can be used to augment the point cloud based horizon estimation to produce a more accurate horizon estimation when the vehicle is pitching at a high rate. The gyroscope data can also be used to correct individual point clouds, which may be distorted if the vehicle is pitching or rolling during an individual scan.
