Design And Research Of Naked-eye3D Mobile Video Equipment

Naked-eye3D technology has important practical value and economic significance in portable devices.Portable naked-eye3D video equipment as a perfect function application system, including small size3D screen design, hardware circuit system and3D player ect. The key problem in our research include the hardware structure of embedded naked-eye3D video equipment,3D algorithm and software.In this paper, the structure and compose of embedded naked-eye3D video equipment were researched.A performance perfect portable video device includes embedded processor and some function modules. Embedded naked-eye3D video equipment select the high-speed embedded processor S3c6140as the main control chip and expand memory,3D sensor, touch3D screen, GPS\WIFI\GSM ect.The performace, interface and extended function of the S3c6140was researched, and the signal interface and electrical characteristics of important modules was also researched, on this basis, system planning and design was completed preliminary.Furthermore, the custom method of embedded operating system and hardware matching was researched.Android operating system with powerful function, rich API interface and stability ect, become the one of main operating system of embedded devices.The embedded hardware system need to matched the operating system, can effectively management and control the system resources.In addition,3D player was also researched.In order to make the stereo image met different sizes3D screen display requirements, acquiring the correct3D image, the dual view stereo image synchronous scaling algorithm and interpolation algorithm was put forword.In order to ensure the accuracy of pixel location, we use the linear scaling method to put every image zoom to the screen resolution, then use column interpolation algorithm to complete the pixel writing of the left and right eye image, so that make the image satisfied optical requiments of naked-eye3D screen.After optimization, the programes can be run in the embedded devices of different sizes liquid crystal screen, meet the pixels position requirement of left and right image.
