Description

Technical Field

[0001] The present invention relates to the technical field of holographic display, and in particular to a movable flying holographic aerial imaging device. Background Art

[0002] With the advancement of science and technology, holographic projection technology has gradually attracted widespread attention due to its ability to create three-dimensional stereoscopic images. However, traditional holographic projection is mostly limited to fixed places and it is difficult to achieve flexible movement in space. Therefore, developing a device that can fly and display holographic images in the air will greatly expand the application scenarios and expressiveness of holographic technology.

[0003] An aerial image display device with reference announcement number CN115244451A includes an image display unit that displays images; an aerial imaging optical system that causes diffused light emitted from the image display unit to be reflected and transmitted multiple times, thereby causing the diffused light to be re-imaged in different spaces; a viewpoint position detection device that obtains viewpoint position information of an observer observing a location where the diffused light is re-imaged by the aerial imaging optical system; and a display control processing unit that controls the image from the image display unit when detecting the observer's position moving from an area located at the front end of the location where the aerial imaging optical system re-images the image to an area between the aerial imaging optical system and the location where the image is re-imaged. Based on the above, it can be seen that although the device can be well applied, it is usually not convenient to flexibly move to a designated area for displaying holographic images, so that there are still certain inconveniences in the use of the device, which needs to be improved.
