3D Autostereoscopic Display Software Design And Research

This thesis comes from"autostereoscopic display research of full colorful three-dimensional show"and"autostereoscopic display software design and research", which are explored for Huadong photoelectric technique institute of Anhui province. Autostereoscopic display is based on parallax illumination and double-image display. The function of parallax illumination is to send odd pixel to right eye, and even pixel to left eye. The autostereoscopic display software of three-dimensional is to set up left and right images, which are with a deep sense in viewers' mind. In addition, this software has the basic function of three dimensions of every software, and also creates corresponding software compensation on displaying effect for the hardware of autostereoscopic display.In this thesis, the geometry optics and simulation modeling based on parallax illumination is shown;the energy distributing of single eye seeing odd pixel or even pixel in front of LCD is set up;the theoretical connection between the system configuration parameters and the stereovision parameters is explained, which is the premise for the hardware structure and the software design of autostereoscopic display. In this thesis, the main frame of software, which is based on Direct3D, technique of three-dimensional browsing, is discussed;according to the mapping transforming from space of virtual 3D to display surface, the connection between double eyes setting in virtual 3D and horizontal position disparity in displaying surface is mainly introduced;according to the mapping transforming from display surface to real space, the connection between horizontal position disparity in displaying surface with deep sense, front scene, back scene is revealed, and the smallest distortion and the best comfortable effect is achieved.Autostereoscopic display in market mainly achieves pixel inserting of odd and even on full screen using hardware changing. It's suitable for entertainment, and the rate is satisfactory. But this method on autostereoscopic display has operation trouble, affecting the software' s function. Through adding button for pixel inserting of odd and even on work screen, operating pixel on display surface, and changing green pixel, the biggest rate could be 0.05s per frame on mainly autostereoscopic display. The main purpose of this task is to research the technique of odd and even pixel inserting, reduce the cost of autostereoscopic display, expand the application of autostereoscopic display.
