Abstract
Vibrometric signatures of portions of a vehicle, such as a joint between two or more aspects of the vehicle, may be generated and used to make determinations regarding the integrity or suitability of the vehicle for one or more missions. Vibrometric signatures are generated based on imaging data captured with the vehicle subjected to excitation over a range of frequencies, and power levels of vibrations of the vehicle are calculated based on the images. Pixels corresponding to surfaces on either side of a joint are selected and vibrometric signatures calculated for such surfaces are compared to determine whether the joint adequately transfers vibrations, or whether the joint is sufficiently tight. Where the vibrometric signatures are sufficiently similar to one another, the joint may be presumed to be tight. Where the vibrometric signatures are not sufficiently similar to one another, the joint is presumed to require maintenance or inspection.
