Architectural Layers & Computer Vision Stack

• Couche 1: Ingestion des Capteurs et Normalisation de Profondeur (RGB-D / Time-of-Flight (ToF) / 60 GHz Radar / Bilateral Filtering): Low-latency frame grabbing, multi-view depth alignment, active illumination noise reduction, and epipolar stereo rectification.
• Couche 2: Régression Neuronale de Points Clés et Extraction de Repères (YOLO-Pose / Heatmap Deconvolution / 21-Point Hand / 33-Point Body): Anchor-free palm detection, high-resolution heat-map deconvolution, and 3D sub-pixel anatomical landmark coordinates regression.
• Couche 3: Cinématique Biomécanique et Résolveur de Trajectoire d Intention (Inverse Kinematics (FABRIK) / Adaptive Kalman Filter / Bi-LSTM Attention): Joint constraint enforcement, jitter elimination, trajectory velocity vector smoothing, and predictive pre-contact intention forecasting.
• Couche 4: HMI Touchless Industriel et Gouvernance Ergonomique (OpenXR / ISO 11226 / REBA-RULA / WebGPU Shaders / CAN-Bus Gateway): Semantic interaction mapping, medical-grade sterile touchless command dispatch, continuous ergonomic fatigue scoring, and OSHA auditing.
