I. Definition and Operating Principle
- I.1 Definition: Augmented Reality (AR) superimposes context-aware digital information—3D models, P&IDs, telemetry, procedures—onto the user’s view of physical equipment via head-mounted displays, tablets, or see-through smart glasses.
- I.2 Operating Principle: AR engines perform real-time pose estimation and registration to align virtual content with physical assets using markers, spatial anchors, or model-based recognition.
- I.3 Core pipeline: capture ? localize ? render ? interact.
- I.3.1 Sensors: RGB-D/ToF cameras, IMU, GNSS (outdoors), plus industrial data via OPC UA/MQTT.
- I.3.2 Localization: Visual–Inertial SLAM; anchors tied to BIM/digital twin coordinates.
- I.3.3 Rendering/Interaction: Hands/voice gestures for step guidance; IoT overlays (pressure, temperature, vibration); remote expert annotations.
- I.4 Performance and error metrics:
- I.4.1 Latency budget: $$L_{total}=L_{capture}+L_{compute}+L_{network}+L_{render}$$ For comfortable alignment, target $$L_{total}\leq 50\ \text{ms}$$.
- I.4.2 Registration error: $$\varepsilon_{reg}=\lVert \mathbf{x}_{virtual}-\mathbf{x}_{physical}\rVert$$ Maintain $$\varepsilon_{reg}\leq 10\text{–}20\ \text{mm}$$ for bolt-level tasks; =50 mm for layout checks.
- I.4.3 ROI estimator: $$ROI=\frac{(\text{Travel Saved}+\text{Downtime Avoided}+\text{Rework Avoided})-\text{AR TCO}}{\text{AR TCO}}$$
