An intelligent dual-lens photographing device and a photographing method therefor. The photographing device comprises a first photographing module, a second photographing module, a shutter, a first driving mechanism, a second driving mechanism, a third driving mechanism, and a controller. The shutter is connected to the second photographing module. The first photographing module and the second photographing module are driven by the first driving mechanism to horizontally rotate synchronously. The first photographing module and the second photographing module are driven by the second driving mechanism to rotate around the horizontal axis synchronously. The second photographing module is driven by the third driving mechanism to horizontally move and/or pitch independently. The shutter, the first driving mechanism, the second driving mechanism, and the third driving mechanism act under the control of the controller. The intelligent dual-lens photographing device uses a wide-angle photographing module to synchronize and track a moving photographing target, and then uses a zoom long-focus photographing module to perform waiting photographing on the photographing target, so as to improve the photographing quality.
