Structure of Motion
We decided to give Photogrammetry and Structure of motion a try! We headed to the Colonial Park Cemetery in Savannah, Georgia to take images of tombstones. We each chose a tomb to focus our study on. We took images all around the object, with no more than a five-degree overlap. Ideally, you want to have between 20-40 pictures when done. This is important because the program has to be able to identify the relation between the images to create the 3D model.
Once we had pictures from every side of the object, we took some images of the top of the tomb and any details that may be difficult for the program to grasp. When finished, we took two measurements of an obvious edge or element on the object to later size the model. We could not import our captured images into Autodesk ReCap 360. Autodesk Recap allowed us to import all our images and decide what quality and file form we wanted it to download the project in. For 3D printing our models later on, we saved the project as a .rcm, .obj and .fbx file. After submitting the project to Autodesk ReCap, we waiting for further notification that our model was completed. Considering the 3D form is pieced together using images, some aspects of the model can be a little distorted or faulty, this is where MeshMixer comes in! We will be utilizing the program MeshMixer to clean up our model and correct and "holes" which may have appeared in the project.
