Referring to fig. 1, fig. 1 is a schematic flow chart of a holographic graphic projection method according to an embodiment of the present disclosure. The graphic holographic projection method is applied to a terminal, and the method can comprise the following steps:

step 101, obtaining the refractive index of air in the space above the terminal screen.

In some embodiments, the obtaining the refractive index of the air in the space above the terminal screen comprises:

acquiring the screen refractive index of the terminal screen;

and calculating the refractive index of the air in the space above the terminal screen based on the incident angle, the refraction angle and the screen refractive index.

Here, the refractive index of air in the space above the screen can be calculated by the formula n ═ sin i/sin r. In the formula, n is refractive index, Sin i is sine of light incidence angle, and Sin r is sine of refraction angle.

In some embodiments, after obtaining the refractive index of the air in the space above the screen of the terminal, the method further includes:

judging whether the refractive index meets a preset requirement or not;

The refractive index of the air in the space above the terminal screen, which is obtained at this time, may not meet the preset requirement, and therefore, the refractive index of the air in the space above the terminal screen needs to be adjusted, so that the adjusted refractive index meets the preset requirement. Wherein, the preset requirement may be: the target light spot positions corresponding to the vertexes of the target figure in the space above the terminal screen can be calculated according to the refractive index and the target figure to be projected.

The air density in the space above the terminal screen can be adjusted by changing the temperature of the air in the space above the terminal screen, so as to change the pressure in the air (which can be realized by a Kerbelon equation). Wherein the temperature of the air in the space above the terminal screen can be changed by controlling the amount of heat dissipated from the terminal screen.

And 102, calculating target light spot positions corresponding to all vertexes of the target graph in the upper space of the terminal screen based on the refractive index and the target graph to be projected, wherein the light intensity formed by the light emitted by the terminal screen at the target light spot positions meets the preset light intensity requirement.

Wherein, the target graph can be a three-dimensional image.

In some embodiments, said calculating, based on said refractive index and a target pattern to be projected, a target light point position in said upper space of said terminal screen corresponding to each vertex of the target pattern comprises:

Step 103, determining position information of a connecting edge between the target light point positions based on the target light point positions and the target graph.

However, after obtaining a plurality of target spot positions, in order to determine which target spot is connected to which target spot, it is necessary to determine position information of a connection side between the target spot positions from the target pattern.

And 104, performing holographic projection through the terminal screen based on the position of the target light spot and the position information of the connecting edge, and forming a holographic image corresponding to the target graph in the upper space.

In some embodiments, the performing, by the terminal screen, a holographic projection based on the target light point position and the position information of the connecting edge to form a holographic image corresponding to the target pattern in the upper space includes:

and performing holographic projection through the terminal screen based on the target vector graph, and forming a holographic image corresponding to the target graph in the upper space.

The target vector graph is a 3D stereogram, and the shape of the 3D stereogram is consistent with that of the target graph.

The light emitting parameter may be the brightness of light, the color of light, and the like. In order to display the holographic image corresponding to the target graph, the light-emitting parameters of each position on the terminal screen need to be acquired, and then the target graph is subjected to holographic projection through the terminal screen based on the light-emitting parameters, so that the holographic image corresponding to the target graph is obtained in the space above the terminal screen.
