The work builds on previous research to evaluate the performance of a range of commercial depth cameras and two different registration algorithms in this context. Methods : A multimodal experimental setup was used, testing five depth cameras in seven configurations. Fiducial Registration Error (FRE) and Target Registration Error (TRE) metrics were calculated using Iterative Closest Point (ICP) and Deep Global Registration (DGR) algorithms. A phantom head model was used to simulate clinical conditions, with cameras positioned to capture the face and craniotomy regions. Results : The best-performing cameras, such as the D405 and Zed-M+, achieved TRE values as low as 2.36 ± 0.46 mm and 2.49 ± 0.35 mm, respectively, compared to manual registration that obtains a 1.37 mm error. Cameras equipped with texture projectors or enhanced depth refinement demonstrated improved performance. The proposed methodology effectively characterized the suitability of the camera for the registration tasks. Conclusions : This study validates an adaptable and reproducible framework to evaluate depth cameras in neurosurgical scenarios, highlighting D405 and Zed-M+ as reliable options. Future work will focus on improving depth quality through hardware and algorithmic improvements. The experimental data and the accompanying code were made publicly available to ensure reproducibility.
