Brief Description of Research Project | The objective of the research project was to develop and implement a procedure for transforming point clouds into inputs for finite element analysis. While methods exist for quantifying 3D deformations from point cloud data, they have not been sufficiently evaluated, and the resulting information cannot be leveraged for FEA due to the unstructured nature of the data and complex noise characteristics. More importantly, the resulting scalar field measurements of deformation are not locally smooth and therefore create numerical instabilities when directly mapped to FEA. The purpose of this project was to develop an analytical pathway that addresses these problems, enables new uses for remote sensing, and provides a basis for rapid and quantitative structural capacity in a manner that currently does not exist. |
