    摘要： Embodiments of this application disclose a motor vehicle self-driving method and a terminal device. The method includes: obtaining, by a terminal device, vehicle external-environment data of a position of a motor vehicle and initial positioning precision of the motor vehicle; determining, by the terminal device, a target driving parameter of the motor vehicle based on the vehicle external-environment data and the initial positioning precision; and controlling, by the terminal device, the motor vehicle to drive based on the target driving parameter. In the embodiments of this application, the terminal device determines the target driving parameter of the motor vehicle based on the vehicle external-environment data and the initial positioning precision. In this way, the target driving parameter varies with the vehicle external-environment data, and further matches an external environment, thereby improving self-driving safety of the motor vehicle.

    摘要： This application provides a motion vector prediction method and a related apparatus. The method includes: parsing a bitstream to obtain an index value of a candidate motion vector list; constructing the candidate motion vector list, where the candidate motion vector list includes candidate motion vectors of K control points of a current block, the candidate motion vectors of the K control points are obtained based on a 2N-parameter affine transform model used for a neighboring block of the current block, N is an integer greater than or equal to 2 and less than or equal to 4, K is an integer greater than or equal to 2 and less than or equal to 4, and N is not equal to K; determining, in the candidate motion vector list, target candidate motion vectors of the K control points based on the index value; and obtaining a predicted motion vector of each subblock of the current block based on the target candidate motion vectors of the K control points. This application helps improve coding efficiency in an audio and video coding process, and satisfies a user requirement.

    摘要： The present invention discloses a user permission allocation method and device. The method includes: acquiring currently collected facial feature information of a user; determining a difference degree of the current facial feature information of the user according to the acquired facial feature information of the user and facial feature information included in stored standard sample information; and allocating a user permission to the user according to the determined difference degree. Compared with a manner of using a fixed face threshold, a difference degree of current facial feature information of the user is determined, and when a user permission is allocated to the user, an external factor that affects the collected facial feature information is used as a reference factor, which means that a higher difference degree of the collected facial feature information indicates a lower user permission allocated to the user, so that the user permission of the user is dynamically allocated, a problem of low authentication efficiency is effectively avoided, and a problem of poor authentication security can also be avoided, and authentication reliability of a facial recognition technology is effectively improved.
