This study used a surrogate to explore the accuracy in using LiDAR in small-medium line measurement (30 mm) on a flat surface in different simulated autopsy/postmortem environments. It showed the accuracy is dependent on surface reflectivity, angle of laser incidence, background environment, and orientation of measurement with an average difference of 1.9 mm. This study demonstrated that already a commercially available LiDAR technology is promising in the postmortem environment. Future studies evaluating irregular surfaces, use of organ tissue, alternative devices, as well as inter- and intra-operator reproducibility would further establish the utility of this technology in forensic pathology practice.</p> 2026-09-21T13:41:51Z Dataset Dataset 10.6084/m9.figshare.33954528.v1 https://figshare.com/articles/dataset/Factors_affecting_measurement_accuracy_in_3D_imagery_captured_using_LiDAR_applications_for_the_postmortem_setting/33954528 CC BY 4.0
