Embodiment 1

[0044] The embodiment of the present invention develops a pre-preview system for virtual photography, aiming at introducing a VCS (VideoComparison Summary, Video Image Collection Summary Comparator) pre-real-time preview system to enhance the actor's sense of real-time immersion and record the director's satisfaction with the camera The movement information makes the layout (typesetting) link completely liberated.

[0045] figure 1 A schematic structural diagram of a virtual photography pre-production system provided by an embodiment of the present invention, including: a virtual photography pre-preview system, a motion capture system, and a workstation, and the workstation is connected to the motion capture system and the virtual photography pre-preview system.

[0046] The motion capture system is used to capture the position information of the moving character through optical capture according to the set time interval, and transmit the position information of the character ...

Embodiment 2

[0096] This embodiment provides a kind of pre-production method of virtual photography, which mainly includes the following processing steps:

[0097] Step 1. Capture the position information of the moving character through optical capture according to the set time interval;

[0098] A motion capture system is set, which includes a control box fixedly installed on the top of a vertically arranged support column, four metal rods are stretched out from the control box, and a metal ball is installed at the end of each metal rod to ensure The position of the metal ball does not move, and the light processing device arranged in the metal ball emits infrared light according to the set time interval under the control of the control box, and the infrared light is irradiated on the surface of the character. On the ball, the reflective ball reflects infrared light of the same wavelength to the light processing device in the metal ball, and the light processing device obtains the positio...

Abstract

The invention provides a virtual photography pre-production method and a virtual photography pre-production system. The system comprises a virtual photography pre-viewing system, an action capturing system and a workstation, wherein the action capturing system captures position information of a moving role in an optical capturing manner according to a set time interval, and transmits the position information of the role to the workstation; the virtual photography pre-viewing system receives the position information of the role transmitted by the workstation and a 3D scene, applies the position information of the role into the 3D scene via a VCS, generates lens movement information of a virtual camera, and transmits the lens movement information of the virtual camera to the workstation. The workstation manages the 3D scene information, and associatively stores the lens movement information of the virtual camera and the corresponding 3D scene. According to the method and the system provided by the invention, virtual synchronous photographing is supported when a performer performs, performance of the performer can be mapped to a set 3D model in real time, and thus virtual photographed 3D scene performance can be immediately acquired, and a 3D creation process can be greatly simplified.

Description

technical field [0001] The invention relates to the technical field of three-dimensional photography, in particular to a virtual photography pre-production system. Background technique [0002] In recent years, with the rise of the 3D film and television industry, the mass production of film and television works has become more and more mature. With the pace of mass production of film and television, filmmakers are eagerly looking forward to a feeling like shooting a live-action movie, where they can see the range of motion and performance of the virtual characters they create in real time. At the same time, the photographer also needs a device that can be tried in real time for them to choose from in terms of the control of the lens. [0003] At present, there is no method in the prior art that can generate a virtual camera 3D scene performance in real time according to the performer's performance. Contents of the invention [0004] An embodiment of the present inventio...
