摘要
从立体相机实拍获取静态立体图像的发展历程,揭示立体摄影从银盐技术到数码技术,从辅助立体到裸眼立体显示的演变过程。随着图像信息处理技术的进步,利用单幅图像的深度变换原理处理的平面图像转多视点立体图像与利用两视点立体图像生成中间虚拟视点的插帧技术也多有应用。分析了实拍获取多视点静态立体图像与虚拟视点生成技术的利弊,在高质量、高分辨率裸眼立体显示应用领域,相机实拍获取静态立体图像更具优势;为降低拍摄系统成本,平面转立体与虚拟视点生成技术较具优势。简要介绍了一种可快速调节间距的相机阵列拍摄系统装置。
The development process of static stereoscopic images acquisition from stereo camera shooting reveals the evolution process of stereoscopic photography from silver salt technology to digital technology,from auxiliary stereo display to autostereoscopic display. With the progress of image information processing technology,the planar image transmutation to multi-view stereo image by using the depth transform principle of a single image and the interpolated frame technology using the two-view stereo image to generate an intermediate virtual viewpoint are also widely used.This paper analyzes the advantages and disadvantages of obtaining multiview static stereo images by camera shooting and virtual viewpoints generated by the frame interpolation technology.In the application field of high quality and high resolution autostereoscopic display,camera shooting has more advantages in obtaining static stereo images.In order to reduce the cost of shooting system,the planar image transmutation to stereo image and virtual viewpoint generation technology have advantages.A camera array shooting system device which can adjust the spacing rapidly is described at last.
