Design And Implementation Of 360° Holographic Imaging System Based On Tetrahedron

Holographic imaging technology is a kind of imaging technology with the development of computer media technology.It can truly reproduce the objective world through graphics and images,and show the sense of hierarchy and authenticity of scenes and objects.Compared with the traditional 2D display technology,it has strong interaction and high audience experience.The emergence of holographic imaging technology brings new opportunities and turning points for the development of computer media technology.However,the current holographic technology is mostly used in large-scale dance show or small-scale display of computer-generated images and virtual animation characters.These technologies are too professional and practical for the general public,so it is difficult to popularize,resulting in the poor popularity of holographic imaging technology.Image cutting and image splicing are important technologies for making holographic projection source in holographic imaging system.At present,the research of image processing technology has gradually matured,but there is not a complete set of image processing methods suitable for holographic imaging.This paperrmainly studies how to make 360° holographic imaging of real objects in various states.The main research contents includes the following three points:·A method of making static object holographic video source is proposed.Considering that the static environment of static objects has a great influence on the shooting results,this method generally uses different time periods of a video for splicing.Based on this idea,a video frame synchronization method based on key frame extraction is proposed.According to the different morphological characteristics of different static objects,a key frame extraction method based on video boundary and the key frame extraction method based on the color range of the image main body are designed.The experimental results show that the key frames extracted by the two methods can meet the requirements.According to the results of video source production,it is feasible to use different methods for different static objects.The image of objects is clear and the video playback is coherent.·A method of making holographic video source of dynamic objects is proposed.Considering the different motion states of different dynamic objects,the production methods of moving objects will be different.In this paper,four sides shooting method and the same segment video capture method are proposed,in which the same segment video capture method uses the video frame synchronization method based on key frame extraction to extract the video key frame.According to the results of video source production,different methods for different dynamic objects are feasible,the object motion track is clear,and the video has no frame skipping phenomenon.·The realization system of holographic imaging system is built.In this paper,we build a holographic imaging system implementation platform,which provides video frame decomposition,image clipping,image splicing and video synthesis functions.We can make a complete holographic video source on this system platform.In this paper,we propose a linear irregular clipping and splicing method based on pixel coordinates for holographic image clipping and splicing It can realize cutting or splicing quickly and effectively.
