Method and Apparatus for Obtaining Emission Probability, Method and Apparatus for Obtaining Transition Probability, and Sequence Positioning Method and Apparatus

An apparatus for calculating a transition probability, comprising a memory and a processor, wherein the memory is configured to store a programmable instruction;

• and the processor invokes the programmable instruction stored in the memory, to perform the steps:
• obtaining a plurality of pieces of track data of a terminal in a target region from a third-party platform, wherein the target region is a predetermined geographical region, the plurality of pieces of track data comprise a same environment parameter, the environment parameter is used to indicate an environment in which a terminal corresponding to track data comprising the environment parameter is located, each of the plurality of pieces of track data comprises at least two pieces of location information, the location information is used to indicate a location that is in the target region and that is of a terminal corresponding to track data comprising the location information, and each of a plurality of pieces of location information comprised in the plurality of pieces of track data corresponds to a time stamp;
• and
• calculating a transition probability based on the plurality of pieces of track data, wherein the transition probability comprises at least one transition probability value, and the transition probability value is used to indicate a probability that movement is performed from a piece of location information to another piece of location information after a time interval T.
