Autonomous Underwater Vehicle (AUV /ROV)  object detection models for subsea surveys

Situation

A leader in deep-sea AUV/ ROV operations, faced challenges in survey data processing both onshore and offshore. This hindered efficient monitoring and evaluation of valuable subsea infrastructure and debris fields.

Task

Develop semi-autonomous machine learning models to reliably assess objects from high quality video and images for classification and associated data quality metrics — minimizing manual effort in post processing and supporting time critical on-board mission goals.

Actions

Collaborated with the onshore and offshore teams to collect and manually label image and video material for model training.

  • Engineered a model ensemble:

    • Integrated three image analysis models (CNN, Local Binary Pattern + SVM, Decision Tree) into a “majority rule” consensus system for robust visibility assessment and object detection in the survey area.

  • Optimized for real-world use:

    • Built an easy interface for remote teams, deployable on edge hardware—with no internet required.

    • Provided clear visualizations and audit logs for oversight and future improvements.

Results

  • Accuracy: Achieved up to 95% recall and 90% precision in classifying video quality and detect /classify objects of interest in the survey field.

  • Efficiency: Slashed manual QA workload and reduced costs linked to unnecessary video recapture.

  • Reputation: Enabled business to deliver higher-quality inspection and detection data, strengthening client trust.

  • Scalability: Designed a modular, future-proof solution adaptable for new requirements and advancing full automation.
