Abstract
The invention discloses an algorithm for transforming a two-dimensional (2D) character scene into a three-dimensional (3D) character scene, which comprises the following steps of: firstly partitioning an original 2D image into blocks, taking the blocks which are approximate in colour and brightness as the same blocks, and comparing the original 2D image with a pre-set depth system so as to generate a depth map; then carrying out contour detection on the original 2D image to generate an image contour map; generating a right/left eye image according to the depth map and the contour map; and using the original image as the left/right image directly so as to output a 3D image. In the algorithm, a scene graph is determined by utilizing the depth map and a contour detection technology, a parallax error of left and right eyes for a close shot is increased, and a 3D effect is achieved.
Description
Technical field
The present invention relates to a kind of 2D changes the 3D algorithm, and particularly a kind of personage's scene 2D changes the 3D algorithm.
Background technology
Present stage, panel display apparatus has been widely used in the individual consumer's goods such as notebook computer, computer monitor, TV because in light weight, advantages such as volume is little, little power consumption, radiation is low, quality is good are arranged.
Along with the continuous development of science and technology, the 3D technology is more and more ripe, is also more and more accepted by masses.But main video substantially all is traditional 2D video at present, and the film source of 3D has only the film and the fragment support of only a few.In order to allow the popular 3D effect of better experiencing, 2D changes the 3D technology and is absolutely necessary.
Summary of the invention
The present invention proposes a kind of 2D changes the 3D algorithm, utilizes depth map and profile detection technique, judges scene graph, strengthens the right and left eyes parallax of close shot, obtains 3D effect.
The objective of the invention is to realize that scene 2D changes the 3D algorithm, the present invention is achieved through the following technical solutions:
At first original 2D image is carried out piecemeal and handle, close color, brightness are thought compare same piecemeal, thereby generate depth map with presetting depth of field system; Then original 2D image is carried out profile and detect, generate image outline figure; Generate the right side/left-eye image according to depth map and profile diagram; With original image directly as a left side/eye image, thereby output 3D rendering.
When the original image piecemeal is handled, adopt many pixels grid to be divided into one, specifically the number of pixel is adjusted according to the resolution of original image in each piecemeal.
Preset depth of field system and be divided into up-down structure, upper, middle and lower structure, left and right sides structure, left, center, right structure, the upper right structure in lower-left and upper left bottom right structure.
Utilize generation image outline figure and depth map to meet, close shot place right and left eyes parallax is big, and distant view place right and left eyes parallax is little.
Original image generates image as eye image during as left-eye image; Original image generates image as left-eye image during as eye image.
The present invention utilizes depth map and profile detection technique by above scheme, judges scene graph, strengthens the right and left eyes parallax of close shot, obtains 3D effect.

Embodiment
Come the present invention is done further detailed explanation below in conjunction with accompanying drawing:
As shown in Figure 1, for personage's scene 2D changes the 3D algorithm flow chart, idiographic flow illustrates with summary of the invention.
As shown in Figure 2, be respectively up-down structure, upper, middle and lower structure, the upper right structure in lower-left, left and right sides structure, left, center, right structure and upper left bottom right structure for presetting depth of field system.
As shown in Figure 3, at first original 2D image is carried out piecemeal and handle, adopt many pixels grid to be divided into one, what this example was taked is the 24*16 grid.Processing is sorted out in close color, brightness, compared with presetting depth of field system, can obtain the depth of field from example is up-down structure, thereby generates depth map; Then original 2D image is carried out profile and detect, generate image outline figure; Utilize generation image outline figure and depth map to meet, close shot place right and left eyes parallax is bigger, and distant view place right and left eyes parallax is less, generates eye image; With original image directly as left-eye image, thereby output 3D rendering.
At first original 2D image is carried out piecemeal and handle, adopt many pixels grid to be divided into one, specifically the number of pixel can be adjusted according to the resolution of original image in each piecemeal.Close color, brightness thought compare same piecemeal, preset depth of field system and be divided into up-down structure, upper, middle and lower structure, left and right sides structure, left, center, right structure, the upper right structure in lower-left and upper left bottom right structure, thereby generate depth map with presetting depth of field system; Then original 2D image is carried out profile and detect, generate image outline figure; Utilize generation image outline figure and depth map to meet, close shot place right and left eyes parallax is bigger, and distant view place right and left eyes parallax is less, generates the right side/left-eye image; With original image directly as a left side/eye image, thereby output 3D rendering.
Skilled artisan is appreciated that image outline figure and the only just explanation of implementing in the illustration of depth map in the industry, and all these embodiment are in spiritual scope of the present invention.
