Summary

The House of the Charioteers is a structure located on the western edge of the archaeological site Ostia, Italy. The house is named for the paintings of charioteers that are visible throughout the structure.

The Center for Advanced Spatial Technologies (CAST), University of Arkansas conducted partial high density surveys of the House of the Charioteers in 2007. CAST researchers surveyed the housed with the Optech ILRIS 3D scanner. The original scan files and the final registered point cloud are provided here.

Description of Final Datasets for Archive:

Original scans (unedited) in e57 format (Note: Some are not included in the final registration), transformation matrices for each scan, Registered point cloud in ASCII format. NOTE: A portion of the scans for the House of the Charioteers (those with the Charioteer_ suffix) were aqcuired from a lift boom to provide the necessary vantage points to aqcuire data for some of the structures' tall walls. However, as a result of the windy conditions during the survey and the subsequent movement of the scanner/lift boom, there is movement evidenced in several of the scans. The easiest way to spot this movement is to look for an unnatural ripple or wave pattern in the dataset. This pattern is not always constant and can appear to varying degrees within and between scans. Also, due to insufficient computing power at the time the data were processed, not all of the scans acquired for the House of the Charioteers was registered to one another. The scans that were not included in the final registered dataset have also been archived. Prior to registration 64 of the scans were edited to remove extraneous data. The edited scans were imported into Polyworks IMAlign (and gridded) and then registered. The transformation matrices from the edited scans were exported and are provided here with the original, unedited scans. The final registered point cloud has also been provided as a single ASCII file.
