Metashape is a product by Agisoft which, for the purposes of this project, allows us to stitch together photos into photogrammetry models. By determining common points in hundreds of photographs, this product is able to produce a model of indeterminate size which is akin to the real thing. For examples of the final product, check this out.
Batch Processing provides a way to leave metashape instructions on which tasks you would like it to perform. This allows the user to have more flexibility on longer tasks such as building dense clouds and meshs. A batch process takes 1 or more tasks and can be instructed to save after the completion of each task - reducing the liklihood of repeatin the process later on due to some unforeseen error.
