Problems solved by technology

However, usually the blur of the captured image is often not very obvious, and this method is difficult to work
[0011] In summary, the application of 2D to 3D technology based on a single video is limited and cannot handle the existing massive 2D images; the 2D to 3D technology based on a single image can overcome this problem, but the existing methods rely on preset conditions and specific scenarios

Embodiment Construction

[0035] The present invention will be further described below in conjunction with drawings and embodiments.

[0036] As shown in the figure, the present invention mainly includes four steps:

[0037] 1. Perform grayscale preprocessing on the image to be processed;

[0038] 2 Calculate the two-dimensional Gaussian convolution template according to the two-dimensional Gaussian filter formula;

[0039] 3. Using the obtained two-dimensional Gaussian convolution template to perform two-dimensional Gaussian smoothing filtering on the grayscale image to reduce noise in the image;

[0040] 4 Perform Laplace filtering on the image after two-dimensional Gaussian filtering.

[0041] In the implementation case, the input is a compressed JPEG color image to be processed, and the output is a parallax image corresponding to the image to be processed. The specific processing process includes the following steps:

[0042] (1) Image reading and decompression

[0043] Read the image file to b...

Abstract

The invention belongs to the technical field of computer vision and relates to a 2D to 3D conversion method, in particular to a single image-based 2D to 3D conversion method. The method comprises the following four steps: subjecting an image to be processed to grayscale preprocessing; calculating a two-dimensional Gaussian convolution mask according to a two-dimensional Gaussian filtration formula; performing the Gaussian smoothing filtration of the grayscale image by using the obtained two-dimensional gauss convolution mask to reduce the noises in the image; and performing the Laplace filtration of the image subjected to the two-dimensional Gaussian filtration. The method has the advantages of processing by starting from the image, avoiding the complex input of multiple images or multi-view stereo images, having high applicability, not requiring camera parameters, avoiding complex calibration, correction and other operation, ensuring automatic generation in a whole process, requiring a small amount of calculation, and having convenient application on occasions when high speed is required.

Description

technical field [0001] The invention relates to a method for converting 2D to 3D, in particular to a method for converting 2D to 3D based on a single image, and belongs to the technical field of computer vision. Background technique [0002] In recent years, with the continuous advancement of display technology and visual technology, various new stereoscopic display technologies have emerged, such as projection stereoscopic display technology, polarized light stereoscopic display technology, naked-eye multi-viewpoint stereoscopic display technology, etc. Set off a visual revolution of stereoscopic technology. Stereoscopic display technology, with its strong sense of three-dimensionality and realism, gives people a great shock and makes people linger. , Advertising media and many other fields have broad application prospects. [0003] However, with the rapid development of stereoscopic display technology, there are very few film sources suitable for stereoscopic display. D...
