The invention discloses a roaming immersion enhancement method. The method comprises the following steps of: (1) designing an overall model of a substation area, a local model of each workshop sectionand a road model for connecting each workshop section through modeling software 3DMax; (2) importing all the designed models into Unity 3D to construct a three-dimensional environment of a virtual space, restoring a real substation area size according to a certain proportion, drawing a scene display external curtain in the three-dimensional environment of the virtual space, and mapping panorama live-action image textures of the substation area to the scene display external curtain so as to obtain a scene display external curtain-based three-dimensional virtual scene; (3) accessing a steeringwheel and controlling the steering wheel to simulate practical driving patrol processes of users on roads in the substation area; (4) adding a sound file in the three-dimensional virtual scene by adoption of Lynx, and carrying out triggering and control via an API function; and (5) adapting OculusRift virtual reality eyeglasses, and after entering a certain workshop section to get off, displayinga scene picture in the workshop section via the virtual reality eyeglasses.
