Method and device for sending, receiving and transmitting three-dimensional image data

Abstract

The invention provides a method and device for sending, receiving and transmitting three-dimensional image data. According to the invention, the three-dimensional image data is parsed into a plurality of view data or view data sets at a sending end and the plurality of view data or view data sets can be selectively packaged and sent, and view image combination can be selectively carried out on the view data at a receiving end, so that the three-dimensional image data is transmitted rapidly with another method; based on the sizes of bandwidth and quality requirements of desired images, the quantity of view images to be transmitted is automatically selected and the view data is selectively recombined; the transmission efficiency of the three-dimensional image is improved; what is more, the requirements of different equipment for different image qualities are met; and display of the three-dimensional image is more diversified.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a method and device for sending, receiving and transmitting three-dimensional image data. Background technique [0002] With the development of hardware technology and software, there are more and more 3D (Three Dimensions, three-dimensional) multimedia content, and 3D movies and 3D TVs are more and more popular in the homes of ordinary people. However, it is necessary to transmit 3D data and display 3D images. Bandwidth and hardware requirements are very high. For mobile communication, limited wireless resources will be devoured to a certain extent, and it will also pose a major test to limited power supply equipment. Usually, the transmission of 3D data is represented by 2D (Two Dimensions, two-dimensional) data plus depth data, and it is also transmitted through such a data stream, that is, the complete 2D data and depth data must be transmitted before the 3D images ca...

[0002] With the development of hardware technology and software, there are more and more 3D (Three Dimensions, three-dimensional) multimedia content, and 3D movies and 3D TVs are more and more popular in the homes of ordinary people. Bandwidth and hardware requirements are very high. For mobile communication, limited wireless resources will be devoured to a certain extent, and it will also cause a major test for limited power supply equipment.

Usually, the transmission of 3D data is represented by 2D (Two Dimensions, two-dimensional) data plus depth data, and it is also transmitted through such a data stream, that is, the complete 2D data and depth data must be transmitted before the The 3D image is displayed well. In the case of small bandwidth, this data transmission method is very slow, and it is impossible to choose to transmit image data according to the image quality requirements.
