Abstract: In a data processing method, a processing device performs encoding, based on spatial position data and time position data of a trajectory point of a trajectory according to an encoding rule of a hybrid code of a preset level in an index database, to obtain a hybrid code of each trajectory point. The hybrid code includes temporal information and spatial position information of the trajectory point. The processing device then queries a similar trajectory in the index database based on the hybrid code of each trajectory point. The index database includes hybrid codes of a plurality of levels, and the index database includes hybrid codes with trajectory information that includes a trajectory identifier and a trajectory length.
