Junkers Ju-52 Photogrammetry Model (Kea, Greece -- 205 fsw)

As promised in my last post on the overall Ju52 Project, I've just released a post about the details of the photogrammetry model and links to the on-line 3D model which you can zoom, rotate, etc.

Here is a link to the post will all the details, some photos / videos shot by Ben Lair while I was working on the project, and some screenshots and links to the model:

Background This is the second post for the Junkers Ju52 Photogrammetry project. The first post covered the trip details, information on the Junkers Ju52 airplane, the wreck itself, and still photos…

Here are a couple screen captures of the model. One of the coolest aspects is that it covers quite a bit of the inside as well and you can "see through" the broken out windows out into the ocean floor.

Brett, I watched the video of you moving around taking the pics for the model. How important is it to maintain a consistent distance from the subject when you're taking pictures? Is it fairly critical or does the photogrammetry software account for varying distances when it's knitting the pics together?

The software can account for distance from the target (within reason). It even has lens corrections if the lens type is provided in the EXIF data.

Keeping a consistent distance helps more with lighting and color (assuming you are working with artificial light and not building a natural light model). The software blends the color from all the photos for a specific spot, but if you are inconsistent across the wreck, it will show.

For example, on our second dive there was a current from starboard to port. You can see in the model that the starboard side of the fuselage is "redder" and lit more than the port side. I kept getting pushed into the wreck on the starboard side and pushed away on the port side.
