Given the recent advances in both photogrammetry and structure-from-motion,
a pipeline that capitalizes on the strengths of both fields is now possible.
This paper presents a hybrid system that uses photogrammetric information to
improve the accuracy of structure-from-motion, which in turn provides a more
dense reconstruction. The procedure maintains the required metrological
accuracy and permits measurements between points with no corresponding targets.
The paper provides an analysis of the effects of various camera parameters to
determine optimal scene configurations. Results generated by the hybrid system
for real and synthetic data demonstrate that both more accurate and more dense
reconstructions are obtained than with structure-from-motion alone.
