With the growth of light field imaging as an emerging diagnostic tool for the measurement of 3D particle fields, various algorithms for 3D particle measurements have been developed. These methods have exploited both the computational refocusing and perspective-shift capabilities of plenoptic imaging. This work continues the development of a 3D particle location method based on perspective-shifted plenoptic images. Specific focus is placed on adaptations that provide increased robustness for variations in and measurement of size and shape characteristics, thus allowing measurements of fragment fields. An experimental data set of non-spherical fragment simulants is studied to examine the dependency of the uncertainty of this perspective-shift based processing method on particle shape and the uncertainty of size measurements of fragments. Synthetic data sets are examined to provide metrics of the relationship between measurement uncertainty that can be achieved using this method, particle density, and processing time requirements.
