A companionship object identification method and apparatus, a server and a system. An acquired object image is analyzed to discover a capture time and a capture place of each object captured in the object image; at least two objects, the distance between the capture places of which is within a preset range and the time interval of the capture times of which is within a first preset time interval, are determined to be companionship objects; a companionship object record is generated once; and the companionship object record between the objects is recorded locally in order to provide a query basis for query personnel. Locally recorded companionship object records of all objects can be output, instead of only outputting a companionship object record of specific objects, such that increasingly complex object analysis requirements can be satisfied.
