ing noise from point cloud data with advanced ? ltering al- gorithms, and instantly enhancing and correcting images as they are collected. Our robust machine-learning-based colour correction algorithms help us to see consistent true- colour photos of subsea targets.

When combined with navigational data, it is possible to deliver real-time geo-corrected laser models, and consistent images across incredibly long surveys. This uniformity pro- duces wide area consistent image mosaics without variations in quality from image to image. Adding onboard analysis software, like EIVA’s Onboard Deep Learning, enables the automated detection of pipeline defects and features, to dras- tically reduce analysis time.
