1. A method comprising: receiving a plurality of sensor data sets generated by a plurality of sensors in response to sensing one or more structure systems, a first sensor data set generated by a first sensor, a second sensor data set generated by a second sensor, each sensor data set describing a plurality of structures of the structure systems; generating a plurality of structure pairs, a structure pair comprising a first structure from the first sensor data set and a second structure from the second sensor data set; defining a relational vector set for each structure pair, the relational vector set comprising a plurality of vectors from a plurality of first points of the first structure to one or more second points of the second structure, each relational vector being the shortest vector from a first point to a second point; calculating a relational vector score for each structure pair according to the relational vector set of the structure pair; and calculating an association score for each structure pair according to the relational vector score of the structure pair, the association score of the structure pair indicating a likelihood that the structure pair is fusable.
