Research On High Resolution 3D Reconstruction Technology Based On Integrated Imaging

In recent years,three-dimensional integrated imaging technology has attracted wide attention of researchers.Because of its continuous parallax,no need to wear glasses and a complete field of view.This naked-eye stereoscopic display technology has a long-term prospect.However,due to the inherent characteristics of the integrated stereo imaging system,the target scene obtained by the three-dimensional reconstruction is lower in resolution and the imaging effect is poor.Therefore,through the analysis of integrated stereo imaging resolution,we proposed two methods to improve the resolution of integrated stereo imaging reconstruction based on LED display.This paper first proposed a time division multiplexing method based on sub-pixel multiplexing technology to improve the resolution of integrated imaging reconstructed images.By analyzed the degrading effect of the reconstruction process of the 3D integrated imaging system,it is proposed to increase the display resolution by increasing the pixel point information of the fixed display array unit.According to the sub-pixel multiplexing algorithm,the pixel image information of the three-dimensional scene element image is reused,an element image array with new information is obtained.Then the element image array of the high-frame rate LED display is quickly outputted,and the human eye persistence effect is utilized.The image array information of the group of elements is displayed through a plane.In this way,the information capacity of the limited display array is increased to achieve the purpose of improving the display resolution of the reconstructed image.The second method is a time-division multiplexing based on super-resolution reconstruction to improve the resolution of integrated imaging reconstruction.In order to make the time-division multiplexed element image array contain more scene information.Firstly,a regularization algorithm is used to perform super-resolution reconstruction on a group of element image arrays with parallel displacement.The pixel points are reconstructed on the reconstructed high-resolution image.Extracting,obtained a set of images with the same number of pixels,and had different scene information around each pixel of the image.Then used a high frame rate LED display to improve the playing speed by means of time division multiplexing,and passed the image information of the group of elements through The flat display increased the information capacity of the plane and obtained more scene information,thereby improved the display resolution of the reconstructed image.In this paper,the acquisition process of elemental image is completed by 3Ds Max software,and the optical reconstruction process is completed by using microlens array and high frame rate LED large screen.Through experimental verification,the method of improving the resolution of integrated imaging reconstructed image is feasible.The subjective resolution is obviously improved,the reconstruction effect of 3D object is more realistic,the edge is refined,the detail part is more prominent.The purpose of improving the display resolution of the reconstructed image is achieved.
