AUTOMATED METRIC INFORMATION NETWORK

摘要

A Metric Information Network (MIN) with a plurality of Ground Control Points (GCPs) that are selected in an automated fashion. The GCP selection includes clustering algorithms as compared to prior art pair-wise matching algorithms. Further, the image processing that takes place in identifying interest points, clustering, and selecting tie points to be GCPs is all performed before the MIN is updated. By arranging for the processing to happen in this manner, the processing that is embarrassingly parallel (identifying interest points, clustering, and selecting tie points) can be performed in a distributed fashion across many computers and then the MIN can be updated.

1. A method of creating a geodetic network, comprising:
generating a plurality of ground control points (GCPs) from a set of images where every image in the set overlaps at least a portion of another image in the set, each one of the plurality of GCPs having a geo-coordinate where the GCP is believed to be located and each one of the plurality of GCPs having a error covariance that is believed to exist between that one of the plurality of GCPs and every other GCP, wherein the plurality of GCPs form a geodetic network; receiving additional information about the geo-coordinate of one or more of the GCPs; and after receiving the additional information, updating the geo-coordinate and error covariance of each GCP in the network, wherein the updating is performed without inline image processing.
