Hello @sbwrx,
We don’t have footage of harbor walls exactly (at least, not metal walls), but we have conducted extensive ROV video surveys along the Elliott Bay Marina breakwater (comprised of large stones, or riprap) in Seattle, Washington, as part of a research project with the Port of Seattle. These surveys utilize GoPro 10s mounted on a customized BlueROV2, with one GoPro facing forward, and another facing downward. I recently made a post here on the forums about our methods and the overall project (see here).
We have some footage in the public domain, for example, here’s a downward-facing video, and here’s the forward-facing video from the same survey. The videos were shot in 4K 30fps, though obviously the Google Drive video preview will be a much lower resolution. Would these or similar videos work for you? If so, we can provide more videos that aren’t in the public domain. We also have the complete ROV telemetry logs associated with these surveys, including the Ping Sonar Altimeter data that we’ve appended in. I wouldn’t ask for $, though if you indeed successfully compile a photogrammetry model using these videos, I would very much appreciate you sharing information about those methods, as that’s one of the directions we want to go with our work.
*edit: In terms of underwater structures, I just remembered we also have ROV footage of tire reefs, as well as pilings under the Seattle Aquarium, that might also be of interest.
Cheers!
Zach
