UB88 Full Photogrammetry Model (San Pedro — 190 fsw)

UB88 Full Photogrammetry Model (San Pedro — 190 fsw)

Background When I first started diving the UB88, I was also starting to investigate and learn photogrammetry. At the time (about a year ago), I thought "wow, building a model of the UB88 would be a cool project." I've been posting updates as I've been working on the project over the past year. Doing a [...]

PBM Mariner Debris Field Exploratory Dives (San Diego, CA)

PBM Mariner Debris Field Exploratory Dives (San Diego, CA)

Background After our second dive on the PBM Mariner, we spent a little time scanning the surrounding area to look for more debris. Tyler had found the tire section a short distance away and we had a feeling there might be more. Lora's new sidescan and sonar system on the Marissa are really beneficial when [...]

UB88 Photogrammetry Project — Stern Take 2 (San Pedro — 190 fsw)

Background More than any other photogrammetry project, getting a complete and good model of the stern section of the UB-88 has vexed me. It has been very frustrating and my first attempt failed. Below is a screenshot of the model I made in November 2020 that was only able to resolve the starboard side: Starboard [...]

PBM Mariner Photogrammetry Model (San Diego — 100+ fsw)

PBM Mariner Photogrammetry Model (San Diego — 100+ fsw)

Background Tyler and I first dove the PBM Mariner a couple weeks ago. During that dive, we had very limited visibility so taking pictures was challenging and I built a photogrammetry model based on those photos. It came out relatively well but was incomplete and I didn't get all of the pictures needed to "link [...]
