Photogrammetry is a preferred technique for noncontact measurement of flexible structures such as large membranes. Traditionally, features are projected onto the surface for automatic target recognition between photos. New techniques use the local texture of a surface to match random speckle between photos. This technique produces higher resolution surfaces than possible using distinct targets while offering the same precision. In order to quantify the quality of the surfaces, a set testdoi:10.2514/6.2010-2749 fatcat:mnvyazkfcvc35klas22hddyvnq
