The combined point cloud of the Schenley Bridge.

The combined point cloud of the Schenley Bridge.

Last year, we used our Faro Focus 3D scanner to take several scans of the Schenley Bridge. Up to now, we have been working with the individual scans, but this week, we registered the scans to create a unified point cloud model.

The process was a good learning experience for the students working on the project.  Even though we set up professional spherical targets during the data collection, we found that the targets were too far away to be used by the software for registering the data.  Therefore, we had to fall back to manual registration methods.  In this case, it was quite tricky, since there were virtually no easy points on the bridge for establishing correspondences.  Meng and Varun were ultimately successful, but it required a lot of patience.
