How to Measure Boat Decks without Physical Templates

Do you want to improve your difficult measuring and templating tasks for boat deck replacement?
PhotoModeler can help!

Boat Deck Replacement Sequence


Replace physical templating with digital templating by using your camera.

  • Place targets > Take photos > Load photos into the PhotoModeler software >
  • Solve project > Outline panels > Export to CAD/CAM

If you measure boat decks/floors (e.g. replacing non-skid areas with decking and flooring products such as EVA foam, carpet, or teak), then you probably know it is difficult. Using paper or plastic templates is cumbersome and wasteful. Here we describe how you can do it with a camera and no templates!

Special targets are temporarily placed on the deck (will not damage the boat), and photos are taken. These photos are loaded into PhotoModeler. PhotoModeler calculates where the targets and deck surfaces are in 3D space.  The targets can be purchased or even printed from your printer!

In PhotoModeler you then use a tracing method to outline regions of the deck (such as the edge of non-skid areas).  The output is an accurate 2D drawing with all the deck areas in a cohesive CAD file.

The CAD file is exported from PhotoModeler and imported into your CAD or CAM software for additional cleanup, and tool path planning for each deck section.  The deck material is cut and installed.

The technology behind this magic is called photogrammetry (measuring from photos!), sometimes called photoG or photo-g for short!

We assume that you are familiar with measuring boat decks using traditional templating methods and are already using, or will soon use CAD and CNC cutting. View this to see how it is done: YouTube Video: Modeling Flat Panels – Replacing Physical Templates with Photos.
