Method for optimizing 2D (two-dimensional) to 3D (three-dimensional) conversion of video work

Abstract

The invention relates to a method for optimizing 2D (two-dimensional) to 3D (three-dimensional) conversion of a video work. In the technical scheme, firstly, an original image is reduced and a low resolution depth map is artificially generated, wherein the workload can be greatly reduced when the depth map is generated under the condition of low resolution; and then the depth map is amplified to the size of the original image and a high resolution depth map is generated by utilizing a signal processing method. The method comprises the following steps of: firstly, carrying out filtering treatment on the amplified depth map by utilizing a bilateral filter; carrying out image gradient computation on the original image and the amplified depth map and judging whether important differences exist between the depth map and the original image; then selecting the bilateral filter or a trilateral filter to carry out optimization treatment on the amplified depth map according to a judging result and generating a depth map with high quality; and finally, generating a 3D stereo image by utilizing a depth-based image rendering algorithm. According to the method, on the premise of ensuring the quality of the depth map, the speed of generating the depth map can be quickened. The method can be used for making the 3D video work with high quality and low cost and at high speed.

Description

technical field [0001] The invention relates to a production method of a stereoscopic film and television work, in particular to an optimization method for converting 2D to 3D of a film and television work. Background technique [0002] With the huge success of the 3D movie "Avatar" at the global box office, audiences are eagerly expecting more three-dimensional movies and TV works to enter the market. Playing 3D video will become a major source of income for digital theaters and a key development direction in China. China Radio and Television plans to open ten 3D TV channels during the 12th Five-Year Plan period. The sales volume of 3D film and television in my country has also increased substantially with the decline in prices. However, with the continuous improvement and popularization of 3D film and television hardware, the content and quantity of 3D film and television are far behind the demand. The biggest reason is the technical difficulty of stereoscopic image prod...

However, with the continuous improvement and popularization of 3D film and television hardware, the content and quantity of 3D film and television are far behind the demand

The biggest reason is the technical difficulty of stereoscopic image production, including dual-lens synchronous focusing, the shooting speed is greatly reduced, and post-production is also very difficult.

At the same time, due to the large size of the 3D camera, it cannot be installed in the existing shooting device, and it has become an insurmountable production obstacle for special effect shooting, such as aerial photography and underwater shooting.

The shooting and production of 3D film and television has become the main bottleneck restricting the development

Such a high number of pixels requires a lot of manpower to process, making the production cost high
