Target tracking method and apparatus, electronic device, and storage medium

A target tracking apparatus, comprising processing circuitry configured to:

• obtain, according to a target detection on image data, a plurality of target instances, each of the plurality of target instances corresponding to one of a plurality of tracked targets;
• determine a plurality of trajectory segments, each of the plurality of trajectory segments indicating a trajectory of a subset of the target instances corresponding to a same tracked target of the plurality of tracked targets;
• determine feature information of the plurality of trajectory segments;
• classify a type of each specified trajectory segment of the plurality of trajectory segments into one of a plurality of predefined types of trajectory segment according to the feature information of the respective specified trajectory segment, the one of the plurality of predefined types of trajectory segment corresponding to a maximum probability in a plurality of probabilities of the respective specified trajectory segment that follows a uniform distribution, and each of the plurality of probabilities corresponding to a respective one of the plurality of predefined types of trajectory segment;
• and
• determine, according to the types of the specified trajectory segments, a target tracking result including a same type of the specified trajectory segments.

A non-transitory computer-readable medium storing a program executable by at least one processor to perform:

• obtaining, according to a target detection on image data, a plurality of target instances, each of the plurality of target instances corresponding to one of a plurality of tracked targets;
• determining a plurality of trajectory segments, each of the plurality of trajectory segments indicating a trajectory of a subset of the target instances corresponding to a same tracked target of the plurality of tracked targets;
• determining feature information of the plurality of trajectory segments;
• classifying a type of each specified trajectory segment of the plurality of trajectory segments into one of a plurality of predefined types of trajectory segment according to the feature information of the respective specified trajectory segment, the one of the plurality of predefined types of trajectory segment corresponding to a maximum probability in a plurality of probabilities of the respective specified trajectory segment that follows a uniform distribution, and each of the plurality of probabilities corresponding to a respective one of the plurality of predefined types of trajectory segment;
• and
• determining, according to the types of the specified trajectory segments, a target tracking result including a same type of the specified trajectory segments.
