Description

Technical Field

[0001] The present invention relates to the technical field of holographic projection, and in particular to a holographic projection method, a holographic device and a computer-readable storage medium. Background Art

[0002] A holographic device is an immersive experience device based on naked-eye 3D technology and holographic projection technology, capable of providing users with realistic three-dimensional images and interactive experiences. It consists of a closed cabin and an optical system, and uses complex projection and imaging techniques to present virtual objects or scenes in three dimensions.

[0003] In related art, the edges of holographic devices' capsules are typically designed with bends to block light, darkening portions of the capsule. The resulting shadows enhance the three-dimensional effect of virtual objects or scenes displayed by the holographic device. However, the range and location of the darkening required for different virtual objects or scenes displayed by the holographic device vary. The shadows created by the bends are limited by their size and position, resulting in significant variations in the three-dimensional effect when displaying different virtual objects or scenes, impacting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides a holographic projection method, a holographic device, and a computer-readable storage medium to solve the problem that when the holographic device displays different virtual objects or scenes, there are large differences in the three-dimensional stereoscopic effects due to the influence of fixed shadows formed by bending, which affects the user experience.

[0008] Beneficial effects: By adjusting the brightness of the lamp beads at the corresponding position of the holographic device according to the dimming requirements, the darkening shadow effect can be achieved through the brightness change of the lamp beads, and the darkening shadow effect achieved by the brightness change of the lamp beads can be adaptively adjusted according to the virtual objects or scenes to be displayed by the holographic device, ensuring that different virtual objects or scenes are adapted to different darkening shadow effects, so that the virtual objects or scenes displayed by the holographic device can obtain better three-dimensional stereoscopic effects, thereby improving the user experience.

[0009] In an optional implementation, obtaining a dimming requirement of a virtual object or scene to be displayed by a holographic device includes:

[0027] When the light intensity difference between the light intensity on one side of the holographic device and the light intensity on the other side exceeds a preset threshold;

[0028] The dimming requirement is adjusted accordingly according to the light intensity difference.

[0029] Beneficial effect: When the light intensity on one side of the holographic device is significantly different from that on the other side, the dimming requirements of that side or the other side can be adjusted accordingly to avoid the high light intensity difference affecting the overall display effect of the holographic device.

[0052] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0053] The following combination Figures 1 to 9 , describing embodiments of the present invention.

[0054] According to an embodiment of the present invention, on the one hand, Figures 1 to 5 As shown, a holographic projection method is provided, comprising:

[0055] S1. Obtaining a dimming requirement for a virtual object or scene to be displayed by a holographic device;

[0056] S2. Adjust the brightness of the lamp beads 1 at the corresponding positions of the holographic device according to the dimming requirement.

[0057] By adjusting the brightness of the lamp bead 1 at the corresponding position of the holographic device according to the dimming requirement, a darkening shadow effect can be achieved through the brightness change of the lamp bead 1, and the darkening shadow effect achieved by the brightness change of the lamp bead 1 can be adaptively adjusted according to the virtual object or scene to be displayed by the holographic device, ensuring that different virtual objects or scenes are adapted to different darkening shadow effects, so that the virtual objects or scenes displayed by the holographic device can obtain a better three-dimensional stereoscopic effect, thereby improving the user experience.

[0058] In one embodiment, obtaining a dimming requirement of a virtual object or scene to be displayed by a holographic device includes:

[0059] S11. Obtain display information for the virtual object or scene to be displayed. Specifically, the display information for the virtual object or scene may include information such as the display height, width, thickness, brightness, and position of the virtual object or scene. In a preferred embodiment, the above display information is comprehensively considered to ultimately obtain a dimming requirement that better meets the requirements of the virtual object or scene to be displayed, thereby achieving a better three-dimensional effect.

[0060] S12: Acquire the dimming requirement according to the display information.

[0061] Obtaining dimming requirements based on display information can make the dimming requirements more compatible with the virtual object or scene to be displayed, thereby making the dimming shadow effect produced by adjusting the brightness change of the lamp bead 1 more compatible with the actual content to be displayed, thereby making the three-dimensional stereoscopic effect of the virtual object or scene finally displayed better.

[0062] In one embodiment, adjusting the brightness of the lamp beads 1 at corresponding positions of the holographic device according to the dimming requirement includes:

[0063] S21. Obtain a darkened area according to the darkening requirement.

[0064] S22: Obtain the darkening lamp beads 1 in the darkening area, and adjust the brightness of the darkening lamp beads 1.

[0065] First, determine the darkening area according to the darkening requirements, then extract the information of the lamp bead 1 in the darkening area, and adjust the brightness of the darkening lamp bead 1 in the darkening area accordingly according to the information of the lamp bead 1, so as to finally achieve the darkening shadow effect of the holographic device through the brightness adjustment of the darkening lamp bead 1 in the darkening area, thereby making the virtual objects or scenes displayed by the holographic device more three-dimensional and beautiful.

[0066] In one embodiment, the dimming area is located on the outer circle of the light board 2 .

[0067] The darkening area is located in the outer circle of the light board 2, and its position is consistent with the bend position in the related art. Therefore, when the brightness of the darkening lamp beads 1 in the darkening area is adjusted, the darkening area can play the same role as the bend, generating darkening shadows and improving the three-dimensional effect; since the darkening area can be adjusted according to different virtual objects or scenes to be displayed, the holographic device of the present application can obtain better three-dimensional effects when displaying different virtual objects or scenes, and the user experience is better.

[0068] In one embodiment, adjusting the brightness of the dimming lamp bead 1 includes: turning off the dimming lamp bead 1.

[0069] By turning off the dimming lamp bead 1, the dimming lamp bead 1 can be clearly distinguished from other lamp beads 1, achieving the effect of darkening the shadow.

[0070] In another embodiment, adjusting the brightness of the dimming lamp bead 1 includes: lowering the brightness of the dimming lamp bead 1 .

[0071] By lowering the brightness of the dimming lamp bead 1, the dimming lamp bead 1 can be clearly distinguished from other lamp beads 1, achieving the effect of darkening the shadows.

[0072] In one embodiment, the holographic projection method further comprises:

[0073] S3. Acquire a light intensity signal outside the holographic device.

[0074] S4. Acquire light intensity changes outside the holographic device according to the light intensity signal.

[0075] S5. Adjust the dimming requirement according to the change in light intensity, and adjust the brightness of the display screen and the corresponding light box.

[0076] By adjusting the dimming requirements according to the changes in light intensity outside the holographic device, the adjusted dimming requirements can be more adapted to the current environment of the holographic device, ensuring the three-dimensional stereoscopic effect of the holographic device. At the same time, by adjusting the brightness of the display screen and the corresponding light box, it can also ensure that the display brightness of the holographic device can bring a better experience to users.

[0077] In one embodiment, adjusting the dimming requirement according to the change in light intensity includes:

[0078] S51, when the light intensity difference between the light intensity on one side of the holographic device and the light intensity on the other side exceeds a preset threshold;

[0079] S52: adjusting the dimming requirement accordingly according to the light intensity difference.

[0080] When the light intensity on one side of the holographic device is significantly different from that on the other side, the darkening requirements of that side or the other side can be adjusted accordingly to avoid the large light intensity difference affecting the overall display effect of the holographic device.

[0081] In one specific embodiment, when the light intensity on one side of the holographic device is significantly higher than on the other side, the dimming requirement on that side can be adjusted accordingly to prevent the high light intensity difference from affecting the display effect of the holographic device. Alternatively, the dimming requirement on the other side can be adjusted accordingly; or the opposite adjustment method can be used to adjust the dimming requirement on one side and the dimming requirement on the other side simultaneously. Preferably, the dimming requirement can be adjusted by increasing the dimming area on that side or increasing the brightness difference between the lamp beads 1 in the dimming area on that side and other areas.

[0082] Specifically, in another embodiment, when the light intensity on one side of the holographic device is significantly lower than on the other side, the dimming requirement on that side can be adjusted accordingly to prevent the high light intensity difference from affecting the display effect of the holographic device. Alternatively, the dimming requirement on the other side can be adjusted accordingly; or the opposite adjustment method can be used to adjust the dimming requirement on one side and the dimming requirement on the other side simultaneously. Preferably, the dimming requirement can be adjusted by reducing the dimming area on that side or increasing the brightness difference between the lamp beads 1 in the dimming area on that side and other areas.

[0084] The controller 3 is electrically connected to the lamp beads 1 on each light board 2, and can achieve a darkening shadow effect by controlling the brightness change of the lamp beads 1. The darkening shadow effect achieved by the brightness change of the lamp beads 1 can be adaptively adjusted according to the virtual objects or scenes to be displayed by the holographic device, ensuring that different virtual objects or scenes are adapted to different darkening shadow effects, so that the virtual objects or scenes displayed by the holographic device can obtain a better three-dimensional stereoscopic effect, thereby improving the user experience.

[0087] Each lamp bead 1 is electrically connected to the controller 3 individually, so that the controller 3 can adjust the brightness of each lamp bead 1 individually, so that the controller 3 can adjust the darkened area according to the actual darkening requirements, and then adjust the brightness of the lamp beads 1 in the darkened area. Specifically, the darkened area is first determined according to the darkening requirements, and then the information of the lamp beads 1 in the darkened area is extracted. The brightness of the darkened lamp beads 1 in the darkened area is adjusted accordingly based on the lamp bead 1 information. By adjusting the brightness of the darkened lamp beads 1 in the darkened area, the darkened shadow effect of the holographic device is finally achieved, thereby making the virtual objects or scenes displayed by the holographic device more three-dimensional and beautiful.

That is, at least one light strip located at the edge in the first direction becomes a dimming light strip, and at least one row of lamp beads 1 located at the edge of all light strips in the second direction becomes a dimming lamp bead 1. In this embodiment, the method for adjusting the dimming area includes: when the dimming area increases, the number of dimming light strips can be increased in the first direction to increase the dimming area; the number of rows of dimming lamp beads 1 can be increased in the second direction to increase the dimming area. When the dimming area decreases, the number of dimming light strips can be reduced in the first direction to decrease the dimming area; the number of rows of dimming lamp beads 1 can be reduced in the second direction to decrease the dimming area.

[0089] In one embodiment, the holographic device further includes a light change sensor 4 , which is disposed outside the box and is in communication with the controller 3 .

[0090] The light intensity signal outside the holographic device is obtained through the light change sensor 4, and the light intensity change outside the holographic device is obtained according to the light intensity signal. The dimming requirement is adjusted according to the light intensity change, so that the adjusted dimming requirement is more adapted to the current environment of the holographic device, ensuring the three-dimensional stereoscopic effect of the holographic device. At the same time, the brightness of the display screen and the corresponding light box is adjusted to ensure that the display brightness of the holographic device can bring a better experience to the user.

The lamp bead control element 5 is electrically connected to the controller 3. Upon receiving instructions from the controller 3, the lamp bead control element 5 may individually control each lamp bead 1 on the light board 2.

[0092] In this embodiment, the holographic device further includes a computer 6 , which is electrically connected to the holographic screen 7 and the controller 3 .
