Zemmels et al. (2022) Cartridge Case Scans

Download (1.89 GB)

A repository of cartridge case scans referenced in Zemmels et al. (2022). This data set is useful as a benchmark for testing and validating automatic cartridge case comparison algorithms. This data set could also be used as an interesting application of image processing/computer vision techniques. Each scan is stored in an XML 3D Surface Profile (x3p) file format. These x3ps contain both the scanned cartridge case surface values in a 2D “surface matrix” as well as metadata concerning the parameters under which the scan was taken (scan size, resolution, name of creator, microscope, microscopy software versions, etc.).
