A virtual scene generation method applied to an electronic device is provided. The electronic device identifies object prediction information of each real object in each of real scene images. A first virtual image corresponding to each real scene image is obtained according to the object prediction information of each real object. A second virtual image and a texture difference image corresponding to each real scene image are generated. A target image corresponding to each real scene image is generated according to the second virtual image and the texture difference image corresponding to each real scene image. Once a virtual scene generation model is generated based on the real scene images, the first virtual image, the second virtual image, the target image corresponding to each real scene image, a virtual scene corresponding to an image is obtained using the virtual scene generation model and the virtual scene simulator.
