摘　　要：提出了一种基于分层聚类二维视点合成的集成成像系统。在该集成成像系统中,采用电动平移台结合单个相机的视点采集方式采集稀疏视点图像;为提高视点采集效率,使用基于分层聚类二维虚拟视点合成方法实现图像间的虚拟视点合成,并利用合成的多视点图像通过像素映射得到微单元图像阵列;利用像素映射得到微单元图像阵列,实现计算重建过程。实验结果表明该系统不仅可以满足高效率的三维信息采集,而且在保证合成视点质量的同时还提高了分辨率质量,增加了集成成像应用的灵活性。An integral imaging system based on hierarchical clustering two-dimensional viewpoint synthesis is proposed.In this integral imaging system,a sparse viewpoint image is collected using a motorized translation stage combined with a single camera viewpoint collection method.In order to improve the efficiency of viewpoint collection,a two-dimensional virtual viewpoint synthesis method based on hierarchical clustering is used to realize virtual viewpoint synthesis between images,and the synthesized multi-viewpoint image is used to obtain an elemental image array through pixel mapping.By using pixel mapping to obtain elemental image array,the computational reconstruction process is achieved.Experimental results show that the system can not only meet the high-efficiency three-dimensional information collection,but also improve the resolution quality and increase the application flexibility while ensuring quality of the synthetic viewpoint.
