A multi-view naked-eye 3D cigarette packaging carton, comprising a carton body, a cover, a frame, and a collapsible pyramid holographic projection imager, the collapsible pyramid holographic projection imager comprising a pyramid imaging member and a bottom fixing member, wherein the pyramid imaging member comprises two support plates and a holographic projection film; a middle of the support plate is shaped as a "crisscross" framework; the holographic projection film is fixed between the two support plates; four top-connected projection surfaces are pre-cut on the holographic projection film; and tops of the projection surfaces are fixed at an intersection of the "crisscross" framework of the support plate; four pre-cuts are formed in the bottom fixing member; and pins corresponding to the pre-cuts are respectively provided on bottoms of the projection surfaces; in response to a collapsed state of the collapsible pyramid holographic projection imager, the pyramid imaging member and the bottom fixing member are placed independently in a sheet manner; and in response to an expanded state of the collapsible pyramid holographic projection imager, the projection surfaces are pushed out from hollow portions of the "crisscross" framework of the support plate, and the pins of the projection surfaces are respectively inserted into the corresponding pre-cuts, thereby fixing a bottom of the holographic projection film; and two adjacent edges of the four projection surfaces are connected sequentially to form a pyramid shape, wherein the cover is provided on the carton body; the frame is provided in the carton body; a support portion is provided on the frame, and a lower portion of the support portion is a cigarette packet accommodating cavity; in response to a stored state of the cigarette packaging carton, the collapsible pyramid holographic projection imager is collapsed and then stored on the support portion, and a cigarette packaging carton is stored in the cigarette packet accommodating cavity; and in response to a displayed state of the cigarette packaging carton, the cigarette packaging carton is taken out from the cigarette packet accommodating cavity; the collapsible pyramid holographic projection imager is taken out from the support portion; the collapsible pyramid holographic projection imager is expanded and then placed in the cigarette packet accommodating cavity; an image generation device is provided on the support portion; and a video or an image played by the image generation device is projected to the collapsible pyramid holographic projection imager to form a 3D image. the pyramid imaging member comprises two support plates and a holographic projection film; a middle of the support plate is shaped as a "crisscross" framework; the holographic projection film is fixed between the two support plates; four top-connected projection surfaces are pre-cut on the holographic projection film; and tops of the projection surfaces are fixed at an intersection of the "crisscross" framework of the support plate; four pre-cuts are formed in the bottom fixing member; and pins corresponding to the pre-cuts are respectively provided on bottoms of the projection surfaces; in response to a collapsed state of the collapsible pyramid holographic projection imager, the pyramid imaging member and the bottom fixing member are placed independently in a sheet manner; and in response to an expanded state of the collapsible pyramid holographic projection imager, the projection surfaces are pushed out from hollow portions of the "crisscross" framework of the support plate, and the pins of the projection surfaces are respectively inserted into the corresponding pre-cuts, thereby fixing a bottom of the holographic projection film; and two adjacent edges of the four projection surfaces are connected sequentially to form a pyramid shape, wherein the cover is provided on the carton body; the frame is provided in the carton body; a support portion is provided on the frame, and a lower portion of the support portion is a cigarette packet accommodating cavity; in response to a stored state of the cigarette packaging carton, the collapsible pyramid holographic projection imager is collapsed and then stored on the support portion, and a cigarette packaging carton is stored in the cigarette packet accommodating cavity; and in response to a displayed state of the cigarette packaging carton, the cigarette packaging carton is taken out from the cigarette packet accommodating cavity; the collapsible pyramid holographic projection imager is taken out from the support portion; the collapsible pyramid holographic projection imager is expanded and then placed in the cigarette packet accommodating cavity; an image generation device is provided on the support portion; and a video or an image played by the image generation device is projected to the collapsible pyramid holographic projection imager to form a 3D image.
