Here we present an interactive guidance and navigation system that assists user in acquiring pictures for image
based 3D modeling. To reconstruct an objectโs 3D model, user follows our instruction to take a set of images for
an object in different angles, we calculate their relative viewing positions and spare point cloud data using
structure from motion technique. After we obtain sufficient number of images, we use Patch-based Multi-View
Stereo (PMVS) [1] software to generate dense point cloud data. When displaying dense point cloud, we provide
user an interface to eliminate those noise data points yielded from background construction or re-projection
errors. Afterwards we reconstruct surface mesh as output. Our system provides informative message for failures
while calculating camera poses and helps user how to resolve those problems. Furthermore, we assess the quality
of camera poses reconstruction and generated point cloud to reveal the lack of angles for captured images and
guide user to remedy those information
