Background The UB88 team first located and dove the UB88 sub in 2003. They did multiple dives on the wreck and produced both still pictures and videos. At some point, Gary Fabian took frames from the videos shot by John Walker and created a photo mosaic of the wreck: UB88 Sub Photo Mosaic (Copyright 2007 [...]

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 [...]
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 [...]
UB-88 Photogrammetry Project – Dives 6 & 7
Background In the ongoing project of building a complete, detailed photogrammetry model of the UB-88, Drew Wilson and I went back with Ray Arntz on the Sundiver for two more dives. On my previous dive, I completed the port and starboard hulls to complete the front half of the model. My goal on these two [...]
UB88 Photogrammetry Project – Dive 5 (Forward Section)
UB88 Photogrammetry Project – Dive 4 (Stern Torpedo Tube)
UB88 Photogrammetry Project – Dive 3 (Conning Tower)
UB88 Photogrammetry Project – Dive 3 (Torpedo Tubes)
Intro/Background I've been learning photogrammetry skills and software. I still need to publish my model of the TBM Avenger but that is going to take more work. In the meantime, I was able to conduct my 3rd and 4th dive on the UB88 this week with the express purpose of working on the 3D model. [...]
Photogrammetry – Part 3 (UB88 Project Dive 1/2)
Intro / Background After diving the UB88 wreck a number of times and also starting to delve into photogrammetry, I decided to combine both of these into a rather large project: Build a realistic 3D Photogrammetry model of the entire UB88 wreck. This project represents a number of challenges -- starting with the fact that [...]
Stepping back in time on the UB-88 wreck
In my final post on the UB-88, I thought it would fun, unique, and interesting to post before & after pictures of the UB-88. I've dug up photos from the excellent http://ub88.org website and a few other places of the UB-88 prior to sinking and then I've taken quite a few pictures of the wreck [...]
