A test on Webframes

Webframes digitizing

Yesterday, I made a digitizing of Webframes inside a boat in way of refit. My customer have to CNC cut near 500 plates adjusted between the webframes.
These webframes are particulary difficult to measure with conventionnal tools because everything is inclined.

The idea was to use the Rhinophoto module Countertop and modify a bit the code to adapt for Webframes digitizing and drawing. I made some comments in the code to avoid drawing some un-needed area... (ask me the code : support[at]rhinophoto3d.com, if you want to test).

The customer CNC cuts some rules in wood. I glued the countertop targets on the rules.
.

I made 7 pairs of rules with different length (2 pairs 500mm, 3 pairs 700mm, 2 pairs 900mm).
Inside the boat we positionnate the rules by pair, vertical rule has been glued with "Patafix" (from UHU company)

Under the roof we have "Patafixed" 3 coded targets to get the roof plane

Then some on the inclinated plane which was too small for using the rules

As I did'nt know the space I will have arround the Webframe, I have used an Ultra Wide Angle Tamron 11mm freshly calibrated plugged on my old Nikon D60 (after that test, I saw it would work with a regular Nikkor 18mm).

After one or two tests to learn how to take the shoots in this narrow area, it looks the full webframe area can be digitized with 12 photos.

Then I ran Rhino > Rhinophoto
