Research On The Image Processing Technology Of Naked-eye3D Mobile Phone

As a new type of stereoscopic display technology, viewers are enabled to have a three-dimensional experience by the naked-eye stereoscopic display without wearing3D glasses. Integrating naked-eye3D technology with smart phone technology, stereoscopic display and stereoscopic camera of mobile phone is realized. The superiority of naked-eye stereoscopic display technology in the small screen is made use of, in order to promote the naked-eye3D development of Portable devices.In this paper, based on the principle of stereoscopic display, stereoscopic camera technology and its software were focused on. The principle of stereoscopic camera, the design of hardware circuit, the development of camera driver, the transplantation of embedded operating system, and the development of3D camera application, etc, were involved by the image processing technology research of Naked-eye3D mobile phone.According to the related technology theory of mobile phone and stereoscopic camera, the design scheme of embedded stereo camera system was proposed, which was based on microprocessor S3C6410and operating system WinCE6.0. Dual CMOS sensor, GSM communication module, the wireless network module, touch screen and other peripheral devices, were under microprocessor S3C6410’s core control, and then the debugging system of mobile phone was constituted. Data interfaces and information transmission mechanism were planned, and the overall design schematic of hardware circuit was completed.Aiming at the data acquisition and image preprocessing of image sensor, the software design of embedded application for the camera system was completed, which realized the real-time synchronous capture and save of dual camera OV3640image data. Firstly, the corresponding OV3640camera driver was developed, and then, the application program of stereo camera system based on DirectShow technology and embedded system WinCE6.0was designed. After embedded software system was configured, the corresponding filter graphs and filter graphs manager were created, left camera data stream with right camera data stream was associated, and then the application software of dual camera system was completed. When program was run, in order to achieve the frame synchronization, the typical matching characteristics of the left and right image data stream were analyzed. And then, the loss of frame for the left (right) image was avoided, the needs of the stereoscopic vision for the stereo-pair image were met.The application software of3D image capture based on WinCE6.0embedded operating system was completed by the paper, which met the static and dynamic image capture and storage capabilities of dual CMOS sensor. The debugging and testing of system based on desktop computer and ARM development board was completed, the left and right images were captured and stored stably. In the end, the importance of dual camera frame synchronization capture in the synthesis of the three-dimensional image was analyzed.
