Problems solved by technology
Apply the current large-screen multi-viewpoint naked-eye stereoscopic display technology to mobile phones to realize naked-eye 8-viewpoint stereoscopic video display on mobile phones, which greatly expands the range of stereoscopic viewing angles. The data volume of 8-viewpoint stereoscopic video source is very large. Due to the limited resources of the mobile phone, a large number of stereoscopic video sources cannot be stored on the mobile phone, which needs to be downloaded through the wireless network. There are still some difficulties in realizing real-time playback under the existing high-speed network. In addition, the display size and resolution of mobile phones are very small, usually 480×720, 240×320 and 480×800, etc., which are different from high-definition large-screen displays (1 920×l 080, etc.), and 8-viewpoint stereoscopic display will further reduce the The definition of stereoscopic display, how to further improve the definition of stereoscopic display while ensuring the effect of stereoscopic display is also a problem that needs to be solved urgently. This paper proposes a multi-viewpoint adaptive display method based on grating stereo mobile phone, which can better solve the above two problems

Embodiment Construction
[0011] Such as figure 1 As shown, the multi-viewpoint adaptive display method based on the grating stereoscopic mobile phone selectively transmits the number of stereoscopic video viewpoints on the PC server side, and uses H.264 compression, which greatly reduces the amount of transmitted data. At the same time, the H.264 codec will occupy For a certain period of time, the time delay is about 1-2 s. Through wireless network transmission, the received stereoscopic video source is adaptively displayed on the mobile phone terminal.
[0012] Recalculate the amount of data according to the above method: the display resolution of single-view video source is 272×160, the data amount of single frame YUV format is 272×160×3×8 / 2=522 240bits=63.75KB, according to the frame rate of normal real-time display If it is 25 frames, the amount of Yuv data per second is 63.75×25×8=12750 KB.
[0013] This paper uses the H.264JMVC stereoscopic video coding test model to encode the stereoscopic vi...

The invention relates to a display method, particularly an optical grating stereo mobile phone-based multi-view point adaptive display method. The optical grating stereo mobile phone-based multi-view point adaptive display method comprises the following steps that: step 1: stereo video visual points are transmitted selectively at a PC server end; step 2: H.264 compression is adopted; step 3: compressed data are transmitted through a wireless network; and step 4: received stereo video sources are displayed adaptively at a mobile phone terminal. With the optical grating stereo mobile phone-based multi-view point adaptive display method of the invention adopted, stereoscopic display resolution can be further improved with a stereoscopic display effect ensured.
Description
technical field [0001] The invention relates to a display method, in particular to a multi-viewpoint self-adaptive display method based on a grating stereo mobile phone. Background technique [0002] As a recognized important and basic 3D vision, multi-view stereoscopic video technology has been paid more and more attention by the academic and industrial circles. The mobile terminal has become the multimedia business center of the network, computer, telephone and TV. Realized on the mobile terminal Stereoscopic display has become one of the hot spots in the current video research field. In 2010, Sharp Corporation launched the first real naked-eye smart phone, which is a dual-view stereo phone. Due to the limitation of the number of viewpoints of the dual-viewpoint stereo mobile phone, the range of the stereoscopic viewing angle is very small, and the observer can only watch the stereoscopic effect in a very narrow range. Apply the current large-screen multi-viewpoint na...
