Our on-device neural inference engine processes every frame in real time, surfacing PACP-codeable defects before the crawler exits the pipe.
Trained on 2.8 million annotated pipe frames spanning concrete, PVC, clay, cast iron, and HDPE substrate types. Achieves NASSCO defect detection accuracy above 94% on unseen validation sets.
Runs on an NVIDIA Jetson Orin NX edge module inside the field control unit — no cloud dependency, zero-latency grading in the field.
Every byte captured underground travels a verified, encrypted chain from sensor to client portal. No transcoding loss, no custody gaps.
ARM Cortex-A78 processor handles real-time drive telemetry, wheel encoder feedback, and camera bus management with 1 ms latency budget.
Deterministic RTHardware H.265 HEVC encoder at 80 Mbps produces broadcast-quality footage at one-third the file size of H.264 with zero quality loss perceptible to PACP reviewers.
80 Mbps H.265NVIDIA Jetson Orin NX runs our TXVision ONNX model at 120 fps on INT8 quantised weights — real-time grading without cloud round-trips.
Edge AI / No cloudWheel odometry fused with inertial measurement for sub-centimetre defect chainage. GPS overlay via NTRIP RTK when surface reference is available.
±1 cm accuracyActive closed-loop cooling keeps electronics within safe range even in 70°C pipe environments. Self-test cycle on every deployment start.
