Embodiment 1

[0038] This embodiment provides a 3D image processing method for mosaic projection, which can be used in laser theaters. The executor of this embodiment is a 3D image processing device for splicing and projection, and the device may be a personal computer, a palmtop computer or other equipment. Such as figure 1 As shown, it is a schematic flow chart of the 3D image processing method for mosaic projection according to this embodiment. The 3D image processing method of the mosaic projection includes:

[0039] Step 101, judge whether the storage area of ​​each projection device in the projection system has received the target frame signal, and the display screen of each projection device sends the target frame signal to the projection screen to splice a picture on the projection screen.

[0040] In this embodiment, the splicing and fusion device cuts the projection signal of a picture into multiple original frame signals in advance, sends each original frame signal to the signal ...

Embodiment 2

[0048] In this embodiment, a further supplementary description is made to the 3D image processing method of the mosaic projection in the first embodiment.

[0049] Such as figure 2 As shown, is a schematic flow chart of the 3D image processing method according to this embodiment. The 3D image processing method comprises:

[0050] Step 201, judging whether the target interrupt signal corresponding to the target frame signal sent by all projection devices has been received, the target interrupt signal is sent by the storage area of ​​each projection device after receiving the target frame signal, if the judgment result is yes, then execute Step 202.

[0051] If the storage area of ​​a projection device receives the target frame signal, the projection device sends a target interrupt signal for the target frame signal to the 3D image processing device, so that the 3D image processing device knows which projection devices have received the target frame signal.

[0052] If it is...

Embodiment 3

[0057] This embodiment provides a 3D image processing method for mosaic projection, which can be used in laser theaters. The execution subject of this embodiment is a projection device. .

[0058] Such as image 3 As shown, it is a schematic flow chart of the 3D image processing method for mosaic projection according to this embodiment. The 3D image processing method comprises:

[0059] Step 301: Receive target frame signals, and the display screens of each projection device send the target frame signals to the projection screen to stitch together a picture on the projection screen.

[0060] In this embodiment, the splicing and fusion device cuts the projection signal of a picture into a plurality of original frame signals in advance, sends each original frame signal to the signal processing front-end of each projection device in the projection system, and passes through the signal processing front-end , Drive the display terminal.

[0061] Step 302, storing the target fr...

Abstract

The invention provides a 3D image processing method, a 3D image processing device and projection equipment. The method comprises the steps of judging whether a storage area of each projection equipment in a projection system receives a target frame signal, wherein the display screen of each projection equipment sends the target frame signal to projection curtain to form an image on the projection curtain by splicing; and if a judgment result is yes, triggering the projection equipment to simultaneously send the target frame signals to the projection curtain, wherein a synchronizing signal exists between each target frame signal and the subsequent adjacent target frame signal, and the synchronizing signal is used for triggering 3D glasses to receive the adjacent target frame signals. According to the method and the device provided by the invention, synchronization of the frame signals between the projection equipment can be achieved.

Description

technical field [0001] The present invention relates to projection technology, in particular to a 3D image processing method, processing device and projection equipment for splicing projection. Background technique [0002] In recent years, 3D image display technology based on binocular parallax has been widely used in various fields such as movies, games, simulation, and virtual reality. When the projected image is clearly visible, the projection area of ​​a projection device is limited, so multiple projection devices can be used in large theaters and other occasions to project on the projection screen to form an image, and multiple images are combined to form a 3D picture. [0003] In the prior art, splicing projection is generally realized through a DLP display system using DLP (Digital Light Processing, digital light processing) technology. The DLP display system includes a plurality of projection devices, which project images onto the projection screen, and each projec...
