An apparatus for extending binocular camera positioning range includes: a rotatable base, a positioning module, a judging module, and a controlling module. The rotatable base is disposed on the binocular camera and drives a lens of the binocular camera to rotate. The positioning module calculates, in real time, spatial coordinates of the target to be positioned in the field of vision of the binocular camera according to an image of the target collected by the binocular camera. The judging module determines whether the target to be positioned will go out of the field of vision of the binocular camera soon according to the spatial coordinates. The controlling module may control the rotatable base to drive the lens of the binocular camera to rotate and adjust a direction of the lens of the binocular camera so that the field of vision of the binocular camera always covers the target.
