The embodiment of the invention discloses a method and apparatus for determining a motion locus. The method comprises: a target picture containing a target person is selected from a picture library, wherein the picture library is used for storing pictures collected by all collection points and the collection points are used for collecting address information of pictures and/or equipment carried by people; according to the collection point corresponding to the target picture, at least two target collection points are determined and a first preset period of time where collection time corresponding to the target picture is located is determined as a target period of time; at least one piece of address information that is collected by the part of or all of the at least two target collection points during the target period of time is obtained; and a motion locus of the at least one piece of address information is obtained, the obtained motion locus is associated with the target person, and thus the motion locus of the target person is determined. Therefore, the motion locus of one person can be determined accurately and the accuracy of personnel tracking is improved.
