Archaeological digs typically last up to a few months and can produce up to 2000 sherds of pottery a day. Archaeologists cannot legally return home with their findings, so they must document them at the dig site. Current methods of documenting sherds are costly, time-consuming, and have low throughput in terms of sherds documented. Thus this team has aimed to create a scanner capable of collecting data at a rate of about one minute per sherd, allowing the user to scan 500 sherds over a 10 hour work day. Ideally, the scanner should produce 3D models of the sherds consistently at 0.35mm accuracy, and cost no more than $1500. The processing of data can be done off-site, thus the system must upload the data to cloud storage, where a program may later retrieve the data to auto-process the models such that artificial holders and background objects can be removed with limited human interaction. Agisoft Photoscan is used to reconstruct the model following photogrammetry practices.
