This study explores the application of the Intel RealSense D455 stereoscopic camera for assessing spinal curvature using non-invasive techniques. The research focuses on comparing the accuracy of spine determination through RGB images and corresponding point cloud data generated by the camera. Pilot measurements were conducted on three healthy participants. The study observed consistent deviations across the entire length of the spine, with minor noise in 3D space likely due to slight inaccuracies in distance measurement. These discrepancies were found to be significantly lower than the specified error margins of the camera, likely owing to optimal lighting conditions during the recordings. The findings suggest that the method is accurate enough for research and clinical applications, providing a non-invasive alternative for evaluating spinal curvature.

This study explores the application of the Intel RealSense D455 stereoscopic camera for assessing spinal curvature using non-invasive techniques. The research focuses on comparing the accuracy of spine determination through RGB images and corresponding point cloud data generated by the camera. Pilot measurements were conducted on three healthy participants. The study observed consistent deviations across the entire length of the spine, with minor noise in 3D space likely due to slight inaccuracies in distance measurement. These discrepancies were found to be significantly lower than the specified error margins of the camera, likely owing to optimal lighting conditions during the recordings. The findings suggest that the method is accurate enough for research and clinical applications, providing a non-invasive alternative for evaluating spinal curvature.
