Research On The Effect Evaluation Of ASDS Based On Parallax

Auto stereoscopic display system(ASDS) use several technologies to present different images to both of a viewer's eyes. Auto stereoscopic display systems are intended to replace current 3D displays,which require the user not to wear some sort of filtering system, such as eyeglasses. No one technology can become so dominant in the Auto stereoscopic display systems that Auto stereoscopic display is the most important three-dimensional display technology. Many patents have been issued for Auto stereoscopic display technology, however, only a few practical systems have reached the market.Auto stereoscopic display systems using special optical components so that the left and right eyes view of the creation of space separated, while in the front or the rear display screen interval between the formation of an independent visual area, based on the stereo parallax separation, allowing different views access to the left and right eyes, resulting in three-dimensional parallax, stereoscopic parallax can determine the extent of three-dimensional images and scenes whether to be synthesized.The main issue on Auto stereoscopic displays which is most concerned about is three-dimensional display's quality and effect. To obtain the best results, first of all,we must ensure the right and left eyes of the three-dimensional image and accurate distribution of pixel element in each column, namely corresponding to a different view, image feature matching and extraction must be guaranteed to be accurate. Second, we must ensure that each eye can only get as far as possible their own eyes and picture will not see the other pictures,In order to obtain better and more realistic three-dimensional display feeling,the degree of crosstalk must be small enough.This paper describes the principle of three-dimensional technology; discusses the factors affecting the implementation of Auto stereoscopic display, their analysis, and introduce a detailed s research on stereocopsis stereo acuity projection.Their quality and effects on Auto stereoscopic display systems. Based on the tradition of term usage in relevant documents from domestic and abroad researches, from the human factors and the computer factor,a comprehensive analysis of Auto stereoscopic display systems; based on human-computer interaction(HCI) to analyze the Auto stereoscopic display problems where need to improve. The following five points:1) Based on the evaluation of the principle of parallax perception; 2) based on disparity estimation algorithm for Auto stereoscopic display's image feature; 3) based on three-dimensional's image histogram equalization studies; 4) based on three-dimensional image histogram equalization Efficiency Evaluation; 5)the analysis of the three-dimensional about the Auto stereoscopic display rate. The comprehensive evaluation and analysis of Three-dimensional display's quality and effect on Auto stereoscopic display systems.From these researches,we made the "3D stereo rate"as an evaluation metric to measure the Auto stereoscopic display system.We also discuss the testing and calculation's method,generalize and try to complete the test's estimation and evaluation about the Auto-stereoscopic display systems.
