Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A non-transitory computer readable medium storing computer executable instructions that when executed by one or more processors cause the one or more processors to:
assign overlapping images depicting a geographic region into a cluster based on a connectivity of pairs of overlapping images, wherein connectivity is an amount of overlap between two images in the overlapping images, wherein overlap is based on one or more of: an amount of geographic area depicted in both of the two images, and, a number of shared feature points depicted in both of the two images;
form a match graph comprising nodes indicative of the images in the cluster and edges connecting the nodes, the edges indicative of the connectivity between the images in the cluster;
determine the cluster is above a predetermined bundle adjustment threshold;
utilize a graph-cut algorithm on the match graph to bi-section the cluster into a first sub-cluster and a second sub-cluster, the first sub-cluster sharing at least one node with the second sub-cluster, the first sub-cluster having at least one node not in the second sub-cluster, the second sub-cluster having at least one node not in the first sub-cluster; and
conduct a bundle adjustment process on the images within at least one of the first sub-cluster and the second sub-cluster.
