Zupt’s pipeline inspection-specific technology integrates an inertial navigation system with 5 high-definition cameras to accurately model a greater area of visible pipeline and nearby seabed. In a single, efficient pass of the pipeline, the ROV or AUV flying the pipeline will collect the necessary data to generate a high-resolution point cloud or mesh model of the pipeline section along with any potential free span. The pipeline deliverable provides details on any corrosion, anomalies, length and depth of free span, anode depletion, and more. The resultant pipeline model is scalable and can be integrated with the vehicle positioning solution to provide the absolute position of the entire pipeline survey.
