最近提出的区域重叠Voronoi图（AVDO）方法已被用于生成正射影像拼接的接缝线网络。该方法显示出相当大的潜在优势，无缝马赛克覆盖一个大的地理区域。本文对该方法进行了进一步改进，提出了一种基于AVDO的接缝线网络精化方法。改进的方法包括检测的有效区域的正射图像，一个更通用的算法生成的平分线，并结合瓶颈模型和Dijkstra算法的接缝网络的细化。最后，利用大量的数字航空正射影像对该方法进行了验证，实验结果表明了该方法的有效性。
The area Voronoi diagrams with overlap (AVDO) method was recently presented and has been used to generate a seamline network for the mosaicking of orthoimages. The method shows considerable potential advantages for seamless mosaics covering a large geographic region. In this paper, the method is further improved, and a seamline network refinement approach based on AVDO is presented. The improvements of the presented approach include the detection of valid regions for orthoimages, a more general algorithm for the generation of bisectors, and the refinement of the seamline network combining the bottleneck model and the Dijkstra's algorithm. Finally, a number of digital aerial orthoimages are employed to test the proposed approach, and the experimental results demonstrate its efficacy.
