Embodiment 1

[0037] This embodiment is a method for processing video transitions using a three-dimensional model. The system used in the method includes: an image editor, a non-editing resource manager, and a renderer arranged in a server or server cluster. The image editor There is a 3D model building unit in the device, which is used to build 3D objects, virtual cameras, virtual lights and make their animations, such as figure 1 shown.

[0038] The image editor can be various non-linear editing systems, which can use 3D model files such as .fbx, .obj, .3ds, etc. generated by third-party CG software such as 3DSMAX and MAYA. These editing systems have built-in 3D model building units, which can create 3D objects, virtual cameras, virtual lights, etc. and create animations, and can perform secondary development on imported 3D models.

[0039] The non-linear editing resource manager is a resource library used to store various materials used in editing, templates, and storyboards generated d...

Embodiment 2

[0064] This embodiment is an improvement of the first embodiment, and is a refinement of the "automatic detection" in the "step of marking the replacement surface" in the first embodiment. The "automatic detection" mode described in this embodiment includes the following sub-steps:

[0065] The sub-step of identifying the three-dimensional model data: identifying the object data and virtual camera observation point data used as the start point and end point of the animation of the three-dimensional model for switching.

[0066] The sub-step of 3D object marking: use the relative positional relationship between the virtual camera and the 3D object to determine the replacement surface before and after the transition of the two videos. The method for automatic marking of 3D objects refers to finding two target objects closest to the camera as replacement objects at the start and end positions of the virtual camera animation, based on the spatial positional relationship between th...

Abstract

The invention relates to a method for processing video transitions through a three-dimensional model, and the method comprises the steps: building a three-dimensional animation switching module and switching three-dimensional animations, wherein the step of building the three-dimensional animation switching module comprises the following steps: marking a replacement plane and carrying out storing, and the step of switching three-dimensional animations comprises the following steps: obtaining image data, selecting a template, carrying out replacement, rendering, and outputting. Through the arrangement of the three-dimensional model template, the method achieves the quick adding of the three-dimensional animations into a video transition, and enables the editing process of three-dimensional animation switching to be very simple. The method employs a mode of automatic detection or interaction arrangement to support a three-dimensional article template, and the identification information of a three-dimensional article is built in advance. When there is a need, the template can be used without any editing and arrangement. Only if an icon of the representative temperate is pulled by a mouse to a joint position of two videos in a story template, can the actual operation process of broadcasting or editing be carried out.

Description

technical field [0001] The invention relates to a method for processing video transitions by adopting a three-dimensional model, which is a processing method for computer digital video files and a method for constructing video files. Background technique [0002] Video transition is used for the transition between two videos. It is a method commonly used in TV program production. Its brilliant effect can improve the production quality of the program. The transition of video can be regarded as a kind of animation, and the commonly used transition methods are divided into two categories: two-dimensional transition and three-dimensional transition. Three-dimensional transitions are more widely used because of their dynamic and vivid pictures. The form of the 3D transition is that when the two screens need to be switched, the page scroll, the card wipe, and the transition between the two faces of the three-dimensional geometric object produce the effect of switching between the...
