Abstract
A system performs rolling shutter correction to transform data captured by sensors of a vehicle, for example, cameras or lidar mounted on a vehicle, for example, an autonomous vehicle. The images captured by a rolling shutter camera mounted on a moving vehicle show rolling shutter distortion. The rolling shutter correction transforms the data representing points of scenes to perform rolling shutter compensation, i.e., compensation for the rolling shutter distortion. The rolling shutter compensation ensures that data representing as three dimensional points, for example, data captured by lidar is consistent with data represented in images captured by a rolling shutter camera. The system performs rolling shutter compensation by estimating a distance travelled by the vehicle between the time that the camera captured a point and the time that the image scan was completed and translating the 3D points by the estimated distance.
