Research On Multi-view Real-time Stereo Imaging Technology In Ultra-high-definition Mode

The lenticular grating has become a representative technology of the naked eye threedimensional display technology.However,it has the shortcoming of not-clear display in 2D mode.In recent years,with the emergence of UHD panels,the problem has been basically solved.As fact that the number of the pixels of real-time stereoscopic display in ultra-high-definition mode is much larger than that in the standard definition,highdefinition mode,it is necessary to study some key points in the ultra-high-definition mode of three-dimensional display applications,such as real-time imaging and synthesis algorithms.Aimed at the above tasks,the paper mainly includes the following research works.(1)Based from the system research of stereo real-time display technology and the practical application of endoscopic stereoscopic display technology,the multi-view stereo display comprehensive verification platform is build.The platform mainly implements the following functions.A)Support real-time simultaneous acquisition of multi-view images,up to 8-channel camera array data;B)The system supports three kinds of standard lenticular grating naked eye threedimensional display,which are two viewpoints,four viewpoints,and eight viewpoints,respectively.(2)Secondly,the static calibration method of the camera array is studied and determined.Based on this method,the calibration work of the integrated verification platform imaging system is completed.The three-dimensional synthesis parameters are adjusted by using the corrected sub-view image sequence,which means the calibration completion of the imaging system and guarantees the best display effect.(3)Next,based on the comprehensive verification platform,a fast algorithm for preprocessing of sub-view image sequence under x86 architecture is proposed.At the same time,the storage method of multi-channel imaging sequence is discussed.The storage coding method is proposed,which is compatible with common image formats such as JPEG.The proposed coding method can provide a sub-view image sequence that carries storage parameters.Combined with the proposed fast algorithm,the sub-view image preprocessing can be real-timely completed.(4)Finally,based on the comprehensive verification platform,a real-time synthesis parallel algorithm of multi-view naked eye stereo display under x86 architecture is studied and realized.For real-time synthesis of 8-channel sub-viewpoint image sequence,the single frame synthesis time is less than 16ms.
