Abstract: A navigation method in the field of intelligent driving technologies includes obtaining images shot by a plurality of cameras; obtaining location information of a target vehicle based on the images shot by the plurality of cameras; after a target parking space for parking the target vehicle is determined, generating a navigation route based on the location information of the target vehicle and location information of the target parking space; and sending the navigation route to a terminal device such that a safety condition in the parking lot can be predicted to assist in safe driving of the target vehicle.

Abstract: An encoding method and apparatus is described. In an encoding method, when a first target sub-block in a target block is obtained, a hash operation is first performed on the first target sub-block. Then, a first hash table is queried for a corresponding hash value according to an operation result, and a corresponding location in a reference block is found according to the hash value obtained by means of query, that is, first reference data is found. The first piece of target data in the first target sub-block is matched with the first reference data, and second target data in the target block is matched with second reference data in the reference block. In this way, an approximate location is predetermined, so that a range in which matching needs to be performed is narrowed, a data compression time is reduced, and data compression efficiency is improved.
