Problems solved by technology

The highest download speed of the three-dimensional mobile phone terminal network is the 3G mobile phone of WCDMA standard. The theoretical download speed is 7.2Mbps, which is about 925.2KB / s, but the actual speed cannot reach it. The measured network maximum download speed is 220KB / s. 3G network speed will be lower

Embodiment Construction

[0030] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0031] In this embodiment, the 8-viewpoint grating Meizu M8SE stereo mobile phone is used as a stereoscopic mobile display terminal, and the displayed resolution is 720*480. It can be calculated that the resolution of a single-viewpoint video source is 272*160, and the data volume of each frame of image is: 272 *160*3*8=1044480bits=127.5KB, according to the normal real-time display frame rate of 25 frames (considering the mobile phone hardware requirements), the amount of data per second is 127.5KB*25*8=25500KB=24.9MB. An application scenario of this embodiment is as figure 1 shown.

[0032] The real-time playback of the system requires the system to transmit 24.9MB of data per second, but the actual network download speed cannot meet the system requirements. In order to solve such problems, the steps of the multi-viewpoint adaptive display method in this e...

Abstract

The invention belongs to the technical field of free three-dimensional mobile phone display, relating to an adaptive displaying method for grating viewpoints based on a mobile terminal. The adaptive displaying method comprises the following steps: obtaining the current network transmission rate v; according to a single-viewpoint video source resolution ratio, calculating the three-dimensional video data volume S which needs to be transmitted per second; calculating the number (n) of viewpoints which can be transmitted; according to the value of n, carrying out adaptive selection on a server end video source: caring out wireless transmission on the selected video source; displaying the transmitted n viewpoints at a mobile terminal according to a rule disclosed in the specification of the invention; and carrying out wireless transmission on the selected video source. In the method, the three-dimensional viewpoints are transmitted as much as possible under the existing bandwidth condition, the received three-dimensional video sources are re-arranged at the mobile terminal, and the three-dimensional impression and definition on the multi-viewpoint free three-dimensional display terminal can be remained to the greatest extent.

Description
