A validation study of the measurement accuracy of SCENE and SceneVision 3D software programs

Abstract

This descriptive study sought to determine the measurement accuracy of two 3D modeling software programs used in crime scene processing and reconstruction. These two programs are FARO's SCENE and 3rdTech's SceneVision 3D. This study compared the measurement difference means to guidelines published by the National Institute for Standards and Technology (NIST). A statistical analysis was performed by subtracting the manual measurement from the measurements from SCENE and SceneVision 3D. These differences were used in a paired t-test. The measurement difference means for each program were found to be within the NIST guidelines. The outcome of the paired t-test showed a statistical but not practical significance in the measurement differences. SCENE was found to be slightly more accurate than SceneVision 3D.
