Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:   study the problem of visual loop closing for long trajectories in an urban environment.  use GPS positioning only to narrow down the search area and use pre-built vocabulary trees to find the best matching image in this search area. Geometric consistency is then used to prune out the bad matches.  compare several vocabulary trees on a sequence of 6.5 kilometers.  experiment with hierarchical k-means based trees as ll as extremely randomized trees and compare results obtained using five different trees.  obtain the best results using extremely randomized trees. After enforcing geometric consistency the matched images look promising for structure from motion applications.
