Description

Technical Field

[0001] The present invention relates to the field of 3D display technology, and in particular to a 3D content presentation method. Background Art

[0002] 3D display is the process of presenting a stereoscopic image on a plane in the form of a plane projection or perspective view. The three-dimensional display system also includes: desktop stereo display system, single-channel three-dimensional projection display system, dual-channel stereo projection display system, multi-channel ring screen projection stereo display system, CAV three-dimensional stereo display system. Traditional 3D display technologies mainly include chromatic aberration, polarization and active shutter types. While these methods provide stereoscopic visual effects, they also have problems such as reduced picture resolution, reduced brightness, and inconvenience in wearing equipment. With the rapid development of virtual reality and augmented reality technologies, the market demand for higher quality and more convenient 3D content presentation methods is becoming increasingly urgent.

[0003] The virtual canvas is the 3D content and corresponding 3D display device required to realize naked-eye 3D display. The intermediate canvas Surface is used to carry the 3D source content required for 3D display, such as 3D videos, pictures, models, etc.

[0004] Generally, a virtual canvas is used as a carrier of the 3D content source to realize 3D display. A physical screen is required to carry the 3D display. Therefore, this scenario is suitable for a laptop or a computer system that already has a monitor. The main screen of the laptop or the 2D screen of the computer system can be used as an intermediate screen to carry the 3D source content. However, when the system has only one physical screen, namely the 3D screen, this method has certain limitations. We need a new method to realize this function and a new operation interface. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a 3D content presentation method, which solves the problems mentioned in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a 3D content presentation method, specifically comprising the following steps:

[0007] S1. System startup: 3DAPP program shortcut is located on the desktop;

[0008] S2. Double-click to run 3DAPP: a 3D source preview window appears;

[0009] S3. Use 3D display technology with face tracking: After starting the 3DAPP, the face tracking preview screen will be displayed synchronously. When the 3D source is in left-right or top-down format, that is, two-grid format, the face / eye tracking technology is used. When the 3D source is multi-grid format, such as regular 8-grid, 9-grid, 45-grid, 54-grid, etc., the face tracking technology is not used.

[0010] S4. Prepare 3D source content: 3D source content can be videos, pictures, 3D models, etc.;

[0011] S5, complete 3D display: through S4, 3D content preparation has been achieved, double-click the preview window or execute the shortcut key to process the 3D source image into a 3D picture and present it on the 3D screen, and then the 3D display can be completed;

[0012] S6. Close 3DAPP: You can choose the normal program closing method to exit. After exiting 3DAPP, the intermediate canvas will no longer be processed and the system desktop will be returned to normal.

[0013] Preferably, in S2, the window can be set as a floating window, can be set as a fixed window, and can also be set as a scalable window.

[0014] Preferably, in S3, the screen can be used to remind the user that face tracking is in normal operation, and after the program is running, the user can close the preview screen window of face tracking.

[0015] Preferably, in S4, taking video as an example, we can use an ordinary player to play the 3D video content. After opening the 3D content, drag the player screen to the middle Surface canvas, and generally select the full screen setting in the player.

[0016] Preferably, in S4, it can be checked whether the 3D content presentation meets the requirements. Taking the left-right format as an example, the picture needs to cover the entire preview window. 3D pictures can be opened with a 3D picture browser, and 3D models can be opened with a 3D model browser. The presentation method needs to be specified according to the program description. If the program is adapted to the left-right format 3D content source, it needs to be presented in the left-right format.

[0017] Preferably, in S5, the 3D presented picture will be adjusted in real time according to the position of the face to fit within the corresponding viewing area, so as to obtain a correct 3D display picture.

[0018] Beneficial Effects

[0019] The present invention provides a 3D content presentation method. Compared with the prior art, it has the following beneficial effects: the 3D content presentation method, through S1, system startup: 3DAPP program shortcut is located on the desktop; S2, double-click to run 3DAPP: 3D source preview window appears; S3, use 3D display technology with face tracking: after starting 3DAPP, the face tracking preview screen will be displayed synchronously; S4, prepare 3D source content: 3D source content can be video, picture, 3D model, etc.; S5, complete 3D display: through S4, 3D content preparation has been realized, double-click the preview window or execute the shortcut key to display the 3D source screen After the 3D image is processed, it is presented on the 3D screen, and the 3D display is completed; S6. Close 3DAPP: You can choose the normal method to close the program to exit. After exiting 3DAPP, the intermediate canvas will no longer be processed and the system desktop will be returned to normal; open a window on the system desktop to preview the contents of the intermediate Surface canvas. When preparing the 3D source content, you can operate it as usual. You only need to present the 3D source content to the intermediate canvas, and then you can preview the presented content in the window, and you can check in real time whether the previewed content meets the expected requirements.
