Abstract
The present disclosure relates to a target tracking method, device, system, and non-transitory computer readable storage medium. The method includes: performing target detection on a current frame image to determine an area where a current target is located; extracting a current feature vector and a current position information of the area where the current target is located; acquiring a historical feature vector and a historical position information of an area where each historical target is located in one or more historical frame images; determining a position difference between the current target and the each historical target according to the current position information and each historical position information; determining a feature difference between the current target and the each historical target according to the current feature vector and each historical feature vector; and determining a historical target that is the same target as the current target.
