Microgravity surveys for cavity detection conducted in the interior of buildings require high accuracy during data acquisition and modern processing procedures. We have developed a new method for the calculation of building effects, where geodetic measurements and photogrammetric software PhotoModeler are used. The advantages of the new approach are demonstrated on a small Slovak church, where two crypts were detected using microgravity and GPR methods in summer 2009. We have shown that close-range photogrammetry methods offer a possibility to improve the microgravity data processing.
