摘　　要：针对观看三维场景时如何自由选择视点与立体景物多视点拍摄困难的问题,提出了一种立体图像中间视点生成算法.算法首次使用图像中物体边缘进行特征点提取,然后利用特征点建立Delaunay三角形网格,并通过网格映射进行视差矢量场快速计算,最后通过内插算法进行中间视点图像生成.实验结果表明,合成的中间视点图像质量良好,可以正确地反映原有左右视点内容,并且具有良好的视觉效果.To solve the problems of looking around within a three dimensional scene by freely choosing views and the difficulties of filming stereoscopic scene with multi-view,this paper presented an intermediate view synthesis algo-rithm.The algorithm originally extracted feature points using the edges of objects in the image,then set up Delaunay triangle mesh using the feature points and calculated disparity vector field by mesh mapping,and finally generated intermediate view image through interpolation algorithm.Experimental results show that intermediate view image has good quality,and it can rightly reflect the content of the original views.It also has a good visual effect.
