We developed and deployed a container inspection vision system over 12 weeks. (1) Gate inspection automation: high-resolution camera arrays installed at all terminal gates — 12 cameras per gate lane capturing all 6 container surfaces (top, bottom, 4 sides) plus doors, corner castings, and undercarriage. Capture: images captured automatically as trucks passed through the gate at driving speed (no stopping required for standard containers) — reducing gate processing to under 15 seconds per container. Damage detection: deep learning models trained on 2.8 million annotated container images detecting 28 damage categories per IICL (Institute of International Container Lessors) standards — dents, holes, cracks, corrosion, bent components, missing parts, and structural deformation. Severity classification: each detected damage item automatically classified by severity (cosmetic, operational, structural) with dimensional measurements derived from calibrated camera geometry.
Container identification: OCR reading container number, owner code, and size/type code per ISO 6346 — linking damage records to specific containers automatically. (2) Timestamped evidence: every container movement through the terminal recorded with timestamped imagery — gate in, yard placement, crane operations, and gate out. Damage comparison: automated comparison of container condition between gate-in and gate-out — any new damage occurring during the terminal stay precisely identified and documented. Crane monitoring: cameras on STS (ship-to-shore) and RTG (rubber-tyred gantry) cranes capturing container condition during lifting operations — identifying the exact moment damage occurred during handling. Evidence package: automated generation of damage evidence packages including timestamped photos, damage classification, and dimensional measurements — providing irrefutable evidence for dispute resolution.
(3) Reefer inspection: specialised camera and sensor system for refrigerated containers — visual inspection of refrigeration unit components (compressor, condenser, evaporator, controller), thermal imaging detecting insulation breaches and abnormal temperature patterns, and power connection integrity verification. Reefer health scoring: each reefer assessed with a health score based on visual and thermal analysis — containers with low scores flagged for inspection by reefer technicians before loading. (4) Analytics platform: real-time dashboard showing damage rates by shipping line, vessel, origin port, and container age — identifying patterns (specific shipping lines with higher damage rates, specific vessels causing damage during loading, containers from specific origins arriving damaged). Predictive maintenance: analysis of terminal equipment (crane spreaders, twist locks, and truck chassis) identifying equipment contributing to container damage — enabling proactive maintenance before damage incidents.
Cost analytics: automated calculation of damage liability — attributing costs to the responsible party (terminal, shipping line, trucker) based on timestamped evidence. (5) Integration: TOS integration (Terminal Operating System — damage records automatically linked to container movements, vessel visits, and billing records), EDI messaging (automated damage notifications to shipping lines in COPARN/BAPLIE format), and customs integration (damage documentation provided to customs authorities when required for inspection or duty assessment).
