Abstract: The present disclosure provides a position determining method and apparatus, an electronic device and a storage medium. The method includes: determining whether a target object is located in a blind area of a camera at n historical moments of a historical time queue and a target moment; wherein the historical time queue is configured to store historical position information of the target object at latest n historical moments prior to the target moment, where n is a preset positive integer not less than 2; and in response to the target object being located outside the blind area of the camera at both of the n historical moments and the target moment, determining position information of the target object acquired by the camera at the target moment as the position information of the target object at the target moment.
