The embodiment of the invention discloses a distortion collection method. The method comprises the following steps: determining the pre-shooting angle range of a rotatable camera of a terminal; detecting whether or not distortion exists in a shooting picture of the pre-shooting angle range; if so, determining the rotation direction and the rotation angle of the rotatable camera; and controlling the controllable camera to rotate according to the rotation direction and the rotation angle of the rotatable camera, and performing shooting in a rotating process. Through adoption of the embodiment of the invention, a distortion region in the shooting picture of the rotatable camera can be detected, and the distortion region is corrected in order to reduce the distortion degree of the distortion region.
