The incremental Structure-from-Motion (SfM) technique
has advanced in both robustness and accuracy, but the effi-
ciency and scalability remain its key challenges. In this pa-
per, we propose a novel batched incremental SfM technique
to tackle these problems in a unified framework, where two
iteration loops are contained. The inner loop is a tracks tri-
angulation loop, where a novel tracks selection method is
proposed to find a compact subset of tracks for the bundle
adjustment (BA). The outer loop is a camera registration
loop, where a batch of cameras are simultaneously added
to alleviate the drifting risk and reduce the running times
of BA. By the tracks selection and batched camera registra-
tion, we find these two iteration loops converge fast. Ex-
tensive experiments demonstrate that our new SfM system
performs similarly or better than many of the state-of-the-
art SfM systems in terms of camera calibration accuracy,
while is more efficient, robust and scalable for large-scale
scene reconstruction.
