A method and device for stereoscopic video acquisition for mobile terminal

Abstract

The invention discloses a stereo video acquisition method for a mobile terminal. The method comprises the following steps: inputting a stereo video parameter on a mobile terminal; packaging the stereo video parameter into an XML (X Extensible Markup Language) file; transmitting the XML file and the video content into a server for analyzing by an HTTP (Hyper Text Transport Protocol); according to the analyzed stereo video parameter, carrying out virtual viewpoint calculation on the video content so as to obtain a visual viewpoint image; synthesizing and coding the virtual viewpoint image to obtain the stereo video content; transmitting the stereo video content to the mobile terminal; and carrying out subsequent processing by the mobile terminal. The invention also discloses a stereo video acquisition device for a mobile terminal. According to the wireless communication technology, the video content which needs to be viewed is transmitted to the server for stereo processing, thereby effectively solving the problem of large computational load of stereo video data information.

Description

technical field [0001] The present invention relates to the field of stereoscopic video imaging, in particular to a method and device for obtaining and displaying stereoscopic images using wireless communication technology on mobile equipment. Background technique [0002] In recent years, with the rapid development of mobile terminals such as smart phones and tablet computers. Mobile terminals have gradually evolved into multimedia centers, where you can watch videos, browse pictures, surf the Internet, play games, take pictures, and have various office software installed. More and more functions can be realized by the mobile terminal, coupled with its portability, so the mobile terminal is changing people's way of life. At the same time, with the hot development of 3D movies, people are no longer satisfied with watching stereoscopic movies with special glasses in movie theaters, but are eager to experience lifelike 3D stereoscopic movies comfortably and freely on more por...

Problems solved by technology

In order to obtain the left view and right view of the scene, the current main method is to use image processing software to obtain scene depth information through complex calculations. The amount of data calculated according to this method is very large, and it needs to be completed with a high-end terminal; or Use a pair of professional-grade cameras, and fix them side by side at a certain distance, and shoot the same object at the same time. This method requires that the lens optical parameters of the two cameras are the same, and the shooting angles are the same. The operation is more complicated.

[0004] Although the hardware and software of mobile terminals are developing rapidly, due to the portability and small size of the terminal, its CPU data computing power, memory capacity, display area, battery life, etc. cannot be compared with dedicated desktop computers.

However, the 3D image data has a huge amount of calculation and requires complex analysis and calculation, so there are many problems in viewing stereoscopic images on mobile terminals.
