Abstract:
This disclosure is directed to calibrating sensors mounted on an autonomous vehicle. First image data and second image data representing an environment can be captured by first and second cameras, respectively (and or a single camera at different points in time). Point pairs comprising a first point in the first image data and a second point in the second image data can be determined and projection errors associated with the points can be determined. A subset of point pairs can be determined, e.g., by excluding point pairs with the highest projection error. Calibration data associated with the subset of points can be determined and used to calibrate the cameras without the need for calibration infrastructure.

Claim (Index 18):
The non-transitory computer-readable medium of  claim 12  storing further instructions that, when executed, cause the one or more processors to perform operations further comprising:\n receiving lidar data comprising a point cloud of the environment captured by a lidar sensor having a third field of view overlapping with the first field of view and the second field of view; \n comparing the point cloud to the first image or the second image; and \n determining, based at least in part on the comparing, a correction function representative of a misalignment of at least one of the first camera or the second camera and the lidar sensor.
