Abstract

Operating  rooms  pose  challenges  for  depth  sensing  due  to  variable  illumination  and instrument occlusion. We benchmarked Kinect v2, RealSense D455, and HoloLens 2 across 100 trials simulating surgical conditions. Metrics included mean depth error, temporal stability, and robustness to  glare.  Results  showed Kinect v2  error  at  2.7 mm,  HoloLens 2  at  1.9  mm,  and RealSense at  1. 1 mm.  Stability under surgeon motion was highest with RealSense  (94% valid frames).  Recommendations  include  hybrid  calibration  workflows  and  adaptive  denoising  for clinical adoption.
