DescriptionThis project focuses on photogrammetry--the process of making 3D objects from 2D photographs--and the reverse engineering of this complex process. While a number of disciplines from cultural heritage to natural sciences use photogrammetry, the algorithms used by the most popular (and accurate) software packages are black box because of their proprietary nature. This project takes a synthetic 3D object which can be fully understood on the digital level and reverse engineers the photogrammetry process to determine exactly how accurate the modeling process is. This is of key importance to anyone trying to make reliable models available to remote researchers, especially when items such as fossils are 3D modeled. The researcher needs to have confidence in the final model to draw valid conclusions if they are unable to visit the collection in person. A virtual machine (VM) was created on Jetstream to import synthetic models, capture them, and export those captures for processing. Utilizing a parallel processing workflow on Jetstream, the speed up for creating 3D models allowed for refinement and comparison of workflows and models with much shorter turn-around times.
