In crime scene investigations, 3D forensic evidence such as tire tread and shoe imprints in substances like mud or snow can often provide useful information to identify suspects and victims. This work focuses on evaluating lateral and depth resolutions of the light field cameras that are hand-held, easy to use, and affordable 3D cameras to understand their suitability for forensic applications. A full factorial experiment was conducted with the datasets of light field images of resolution targets (Siemens stars for lateral resolution evaluation and concentric circles for depth resolution evaluation).
