Abstract


With the large scale introduction of the mobile terminal three-dimensional display technology , the rapidly growing demand for 3D modeling and three-dimensional computing technology . Now , a lot of mobile terminal equipment processor units are equipped with high-performance graphics accelerator as well as large -capacity memory memory (RAM), and therefore has a relatively strong graphics rendering capabilities . For wireless applications like gaming applications on handheld devices require the user to interactively , however , some of the traditional three-dimensional basic model parameters need to transfer the amount of data transfer bandwidth greatly limit the effect of the real-time display . The data sets are usually traditional 3D rendering needs exceed the available memory of the mobile terminal and rendering capabilities . Therefore , the more complex three-dimensional scene is displayed in real time on a mobile terminal is still a challenging task . In the case of mobile terminal wireless transmission bandwidth constraints and energy constraints , the paper focuses on the research carried out based on the multi- layers of pseudo- three-dimensional image transmission and display technology . The main work includes building the system structure model , given the pseudo- three-dimensional display critical information required for the transmission and acquisition method in mobile terminal . First study the applications of existing three-dimensional images and three - dimensional rendering method to analyze the prospects for the pseudo- three-dimensional image and video applications , mobile terminal and the characteristics of the transmission network , the establishment of the evaluation system for mobile terminal three-dimensional image transmission and display . Second processed image warping algorithm based on human visual characteristics of the layers , and a generation algorithm based on the depth information of binocular vision , resulting in the transport critical information . To re-establish the software architecture of the system model , hardware framework to achieve the program design of the proposed multi - layer deformation algorithm , and the establishment of a multi- layer classification method and system transfer the amount of data model and eventually given several layers split to automatically adapt to different transmission bandwidth . The simulation results show that multi- layer transport model presented in this paper can produce a similar three-dimensional display , while a very small amount of data required during transmission and adaptive transmission bandwidth . Image warping algorithm and depth of information extraction algorithm is simple, low complexity , in line with the standard of the evaluation system , a wide range of usage scenarios of the future .
