While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs.
The three-dimensional effect displayed on the two-dimensional plane such as the screen or the curtain is the three-dimensional visual effect caused by the deception of human eyes by the shadow effect of the content, and is not the display of the real three-dimensional content. A planar screen cannot realize the display of three-dimensional contents in space, but only a stereoscopic screen can display color and brightness information of three-dimensional contents at each position in three-dimensional space, but the prior art cannot make such a stereoscopic screen.
For realizing such a stereoscopic screen, various designs of screen, transmission, appearance, software, and the like are required. It is first necessary to refresh a flat screen fast enough to ensure that the color and brightness of a location can be controlled to be displayed when the screen is moved at high speed. Secondly, a stable, controllable and rapid motor transmission device is needed, a plane screen is placed through a motor center shaft, and the screen can be rotated by a certain angle at a specified time point. Then, the wind resistance of the planar screen moving in space is reduced by proper design. And finally, accurately controlling the information displayed by the pixels in the screen through a flexible software algorithm.
The persistence effect inspires that since the sampling frame rate of human eyes is generally 20-30 Hz, one can consider that the switching of two adjacent frames is continuous. The design of the stereoscopic screen can be converted into a screen with very high moving speed. When a two-dimensional screen moves to be full of a three-dimensional space within the sampling time of two adjacent frames of human eyes, people can consider that the whole space is provided with contents, if the sampling frame rate of the human eyes is 25Hz, namely, 1s samples 25 frames of images, the two-dimensional screen moves to be full of the three-dimensional space within 1/25s, and therefore the purpose of displaying real three-dimensional contents can be achieved.
In order to achieve the above objects and in view of the problems in the prior art, the present application proposes a three-dimensional content display apparatus, method, device, and storage medium, the apparatus including a main control system, a display system, and an electric power transmission system including a rotation shaft; the main control system is respectively connected with the display system and the electric transmission system, the electric transmission system is connected with the display system through a rotating shaft, and the main control system presets the human eye sampling frame rate and sequentially played multi-frame images through the preset refreshing frequency of the display system to determine the display content corresponding to the display system under the current rotating angle; determining the minimum rotation number of the display system meeting the requirements based on a preset human eye sampling frame rate; the display system is controlled to display corresponding display content under the current rotation angle, and the electric transmission system is controlled to rotate through the rotation shaft according to the minimum rotation speed of the display system, which is determined by the main control system based on the minimum rotation number and the preset human eye sampling frame rate, so that the display of three-dimensional content can be provided for viewers at any positions on a two-dimensional screen.
A three-dimensional content display apparatus according to an embodiment of the present application is described below with reference to the accompanying drawings.
Referring to fig. 1, the apparatus includes:
The display device comprises a main control system, a display system and an electric transmission system, wherein the electric transmission system comprises a rotating shaft;
The main control system is respectively connected with the display system and the electric transmission system, and the electric transmission system is connected with the display system through a rotating shaft;
in some embodiments, the main control system may be mounted on the rotating shaft of the electric drive system as shown in fig. 1 to rotate along with the rotating shaft, or may be mounted at other positions of the three-dimensional content display device.
The main control system is used for acquiring a first refresh frequency of the display system, a preset human eye sampling frame rate and sequentially played multi-frame images, wherein the first refresh frequency is the preset refresh frequency of the display system; determining display content corresponding to a display system under a current rotation angle based on a first refresh frequency, a preset human eye sampling frame rate and sequentially played multi-frame images; determining the minimum rotation number of the display system meeting the requirements based on a preset human eye sampling frame rate; controlling the display system to display corresponding display content under the current rotation angle; the minimum rotational speed of the display system is determined based on the minimum number of rotations and a preset human eye sampling frame rate.
The preset refresh frequency of the display system can be flexibly set based on actual conditions.
In general, a higher screen refresh rate allows the display to update more images in the same time, thereby presenting a smoother, smoother picture. Therefore, in the embodiment of the present application, the preset refresh frequency is relatively high, such as 2700hz,3600hz, and so on.
As the sampling frame rate of the human eye is generally 20-30 Hz, the preset human eye sampling frame rate may be any sampling frame rate in the range of 20-30 Hz, such as 24Hz, 25Hz, etc.
From the above, when a two-dimensional screen moves to fill a stereoscopic space within two frames of sampling time of human eyes, one considers that the whole space has content, and thus, the minimum rotation number of the display system meeting the requirement can include:
The planar display panel can only have one independent display panel, and a stereoscopic space is fully distributed in the movement of two adjacent frames of sampling time of human eyes, and the planar display panel needs to rotate at least one circle around a rotation shaft, namely 360 degrees.
The flat display panel may include two independent flat panels, and in case of back-to-back bonding of the two independent flat panels, moving the two panels within the sampling time of two adjacent frames of human eyes fills a stereoscopic space, and the flat display panel needs to rotate a minimum of half a turn, i.e. 180 degrees, around the rotation axis.
In addition, the minimum rotation number of the display system can be determined based on the preset human eye sampling frequency and the number of independent plane panels in the display system, and the relative relationship between the display system and the rotation shaft comprises any one of the following: the central axis of the display system coincides with the rotation axis, the central axis of the display system is parallel to the rotation axis, and the edge of the display system coincides with the rotation axis.

After the minimum rotation number of the display system is determined, dividing the first refresh frequency by the preset human eye sampling frame rate, and determining the refresh frequency when the display system rotates by the minimum rotation number, namely the integral refresh frequency corresponding to the display system when the display system rotates by the minimum rotation number within the sampling time of two adjacent frames of human eyes.
Further, under the condition that the display system rotates according to the minimum rotation number and the rotation speed is average, based on the minimum rotation number, the multi-frame images played in sequence and the refreshing times, the display content corresponding to the display system under each rotation angle is determined.
In some embodiments, assuming that the minimum rotation number is 180 degrees, the first refresh frequency is 2700Hz, and the preset human eye sampling frame rate is 30Hz, the refresh number is 90 times, that is, the refresh is performed once every 2 degrees of rotation, so that the played image can be refreshed every other degree according to the rotation sequence.
And determining the display content corresponding to the current rotation angle display system based on the display angle corresponding to the rotation angle detector.
In addition, the main control system further comprises a rotation angle detector for determining the rotation angle of the current display system, so that the main control system can determine the display content corresponding to the current rotation angle display system based on the display angle corresponding to the rotation angle detector.
The electric transmission system controls the display system to rotate according to the minimum rotation speed or more through the rotation shaft.
After determining the minimum rotational speed, the main control system may send the minimum rotational speed to the electric drive system so that the electric drive system rotates the display system via the rotating shaft at a speed equal to or greater than the minimum rotational speed.
Rotation of the display system can form a stereoscopic screen, enabling display of three-dimensional content that can be provided to viewers at arbitrary positions.
In some embodiments, the device may further be provided with a sensor for detecting environmental information in which the device is located, if the environmental information in which the device is located includes wind speed and wind direction, for example, the electric power transmission system controls the display system to rotate at a minimum rotation speed through the rotation shaft, and if it is detected that the wind direction is different from the rotation direction of the current display system, the rotation speed of the rotation shaft may be appropriately increased based on the wind speed and the wind direction.
