Embodiment 1

[0019] see figure 1 , a kind of fast method that utilizes depth map conversion 3D image, it is characterized in that, carry out following processing step in 3D software:

[0020] (1) Create a 3D scene model;

[0021] (2) Set up a lighting camera in the 3D scene;

[0022] (3) In a 3D scene, use a ruler to measure the distance from the light camera to the far end of the object to obtain the depth value of Z-Depth;

[0023] (4) In the 3D scene, measure the distance value Length, and set Z-Depth through the distance value;

[0024] (5), Z-Depth value setting maximum value Z-Depth max and minimum Z-Depth min , rendered into a map, and finally a depth map is obtained;

[0025] (6), import video sequence frame, by taking scene as reference Orient Scene, find a horizontal position, to determine the camera perspective angle of video camera to video;

[0026] (7), import the depth map Z-Depth;

[0027] (8) Use the Z channel to add a stereo camera stereo Render, perform forward an...

Abstract

The invention relates to the technical field of three-dimensional rendering, in particular to a rapid method for converting a 3D image by use of a depth image, and the method comprises the steps: rendering a depth map Z-Depth through three-dimensional making software; utilizing a depth map Z- Depth to carry out conversion from 2D to 3D to obtain a left eye view and a right eye view to form a 3D film, so that repeated rendering during 3D film source manufacturing by the three-dimensional manufacturing software is reduced, the rendering time can be saved, the rendering cost can be reduced, the manufacturing period can be greatly shortened, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional rendering, in particular to a fast method for converting a 3D image by using a depth map. Background technique [0002] The existing 2D to 3D technology often requires repeated rendering, which takes a long time to render, and the cost of rendering is high, which greatly prolongs the production cycle and reduces work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, render the depth map Z-Depth through three-dimensional production software, use the depth map Z-Depth to convert from 2D to 3D, obtain the left and right eye views, and form a 3D stereoscopic film. It reduces the repeated rendering when 3D production software produces 3D stereo film sources, which can save rendering time, reduce rendering costs, greatly shorten the production cycle, and improve work efficiency. [0004] In order to achieve ...
