Abstract: A method for calibrating an extrinsic parameter of an on-board sensor includes obtaining first feature point information collected by a first on-board sensor; determining a geographic location of a vehicle body in which the first on-board sensor is located in a world coordinate system; determining second feature point information within a collection range of the first sensor in a map database based on the geographic location of the vehicle body in the world coordinate system; determining a plurality of first feature points and a plurality of second feature points based on the first feature point information and the second feature point information.

Abstract: The present invention discloses a processing method of an event data stream, which is from a dynamic vision sensor, the method comprises steps of: acquiring inertial measurement parameters, which corresponds to one segment of the event data stream for generating one frame of image; determining attitude angle data based on the acquired inertial measurement parameters and calibration parameters of the dynamic vision sensor; generating a transformation matrix based on the determined attitude angle data; processing the one segment of the event data stream using the transformation matrix, to generate the processed event data stream. The present invention also discloses a corresponding computing apparatus.
