A registration method and a registration apparatus for an autonomous vehicle is provided. The method includes: generating a first trajectory curve based on first detection poses of a vehicle-mounted camera at a plurality of first time points, generating a second trajectory curve based on second detection poses of a vehicle-mounted positioning device at a plurality of second time points, aligning the first trajectory curve with the second trajectory curve based on the first detection poses and the second detection poses, and registering the vehicle-mounted camera and the vehicle-mounted positioning device based on the first trajectory curve and the second trajectory curve aligned with each other.
