1. An information playback method, comprising:
performing identification on a spatial image in a 3D model, thereby identifying an information display device and a display area of the information display device in the spatial image;
determining display position information corresponding to the display area; and
overlaying an information playback layer in the display area based on the display position information so as to play back display information in the information playback layer;
wherein playing back the display information in the information playback layer comprises:
obtaining current virtual user visual field information, wherein the visual field information comprises current position information of a virtual user and visual angle range information of the virtual user;
judging whether the information display device is within a visual field range of the virtual user; and
loading the display information on the information playback layer and playing back automatically, or playing back in response to a playback command of a user if the information display device is located within the visual field range of the virtual user; and
wherein judging whether the information display device is within the visual field range of the virtual user comprises:
obtaining spatial coordinates of end points of the information display device in the 3D model; and
determining that the information display device is within the visual field range of the virtual user when the number of the spatial coordinates of the end points falling within the visual field of the virtual user is greater than a preset threshold.
