Embodiment 1

[0038] Embodiment 1 of the present invention provides a method for making a special-shaped screen film, which is used to convert real films of common formats (rectangular 16:9, 4:3, 2.35:1, etc.) into films suitable for special-shaped screens, such as figure 1 shown, including the following steps:

[0039] Step 101. According to the number of projection channels, use the path tool to draw the shape of the real special-shaped screen by channel to form a vector grid. The number of vector grids is the same as the number of actual projection channels.

[0040] Step 102: Project vector grids on the real special-shaped screen, and adjust the vector grids according to the positional relationship between the projected vector grids and the real special-shaped screen, so that the actually projected vector grids are evenly distributed and spliced ​​completely.

[0041] Step 103: Establish a 3D virtual screen body of a real special-shaped screen. The parameters of the 3D virtual screen bo...

Embodiment 2

[0068] A method for making a special-shaped screen film provided in Embodiment 2 of the present invention, comprising:

[0069] The real movie is an active stereoscopic three-dimensional 3D movie, and the method described in Embodiment 1 is used for the real movie for the left and right eyes.

[0070] The realization of active stereoscopic 3D technology requires three elements: the refresh rate needs to reach 120 frames per second, an infrared signal transmitter, and 3D stereoscopic glasses that can accept infrared signals. When the 3D image is generated alternately with the left and right frames in the frame sequence format, these frame signals are transmitted through the infrared transmitter, and the 3D glasses responsible for receiving the signal are synchronized with the left and right frame images at the same time. image.

[0071] Since only one projector is needed for the active stereoscopic 3D movie, the method described in Embodiment 1 is used for the real movie for t...

Embodiment 3

[0074] A method for making a special-shaped screen film provided in Embodiment 3 of the present invention, comprising:

[0075] The real movie is a three-dimensional 3D movie in a passive stereoscopic mode, and the method described in Embodiment 1 is used for the real movie for the left and right eyes.

[0076] Passive stereo mode is also called optical polarization display technology. The main implementation method is to simultaneously project two stereoscopically processed images or films through two projectors, so that the two images with different depths of field are superimposed on the screen. If watch directly with eyes at this moment, the picture that sees is blurred double image, and will see three-dimensional image, will adorn a polarizer before every projector. From the light emitted from two projectors, after passing through the polarizer, it becomes polarized light. Passive stereoscopic methods include side-to-side and top-to-bottom formats.

Abstract

The invention relates to a production method of a special-shaped screen film, comprising: according to the number of projection channels, using a path tool to describe the shape of a real special-shaped screen by channel, forming a vector grid: projecting the vector grid on the real special-shaped screen, according to the projection Adjust the vector grid according to the positional relationship between the vector grid and the real special-shaped screen; set up the three-dimensional virtual screen body of the real special-shaped screen, carry out texture mapping to the three-dimensional virtual screen body with a standard grid, and divide it into at least one Subregions, convert each said subregion into a mesh and separate: create a plane, use the adjusted vector network as the texture map of the plane, adjust the mesh so that the mesh coincides with the texture map of the plane ; Use the real film as the texture map of the adjusted 3D virtual curtain body and render the output. Compared with the prior art, the present invention has the advantages of being simple, fast, and highly adaptable, and is not subject to too many limitations of the construction conditions of the theater itself, and the configuration conditions of software and hardware.

Description

technical field [0001] The invention relates to a video image processing method, in particular to a production method of a special-shaped screen film. Background technique [0002] The production of existing special-shaped screen films is mostly based on the pre-shooting or production of the film and is processed according to the specific conditions of special-shaped screen theaters, which has a lot to do with the construction method of the theater itself and the configuration of software and hardware. Different production methods are often used for the same film to be shown in different special-shaped screen theaters, and some theaters are equipped with specific production tools, which requires that the personnel who provide or use the film must understand various types of special-shaped screen theaters and Related production tools have caused great work difficulties for relevant personnel. Contents of the invention [0003] The purpose of the present invention is to pro...
