How do I make accurate fit-to-foam wrench/tool profiles
-
I wouldn't even consider Match Photo for this job. I would set up the camera on a tripod or copy stand looking straight down and photograph the tools square on. Then import the image as an image, not Match Photo. Trace the tools as needed. You can place a ruler in the photo(s) and use that along with the Tape Measure tool to adjust the size of the image once you get it into the model space.

using a professional grade low visual distortion lens
If it's a zoom lens, use a high focal length to minimize the distortion...
Do you have an example image? -
If you were to photograph the tools on a white background and make that background transparent you could also use TIGs Image Trimmer in his SKM Tools to automatically create the edges.

Cotty- The lens is a nikkor 45mm 2.8 tilt-shift. 50mm would be better, but 45 should be close enough (better than a point and shoot anyway). Sorry, don't have an example on this computer
Dave- I didn't have much luck when I tried the tripod, but I should try it again. thanks for the Plugin!

Jesse, it would be even better to use a longer prime lens.
What kind of tripod do you have? Decent tripods have a screw post on the bottom of the column which will allow you to attach the head there. Or, if the column isn't geared, you can pull the column out and invert it. This would then allow you to use the tripod as a copy stand. Get or make a grid that you can lay down on the surface below the camera to give you guidance in squaring the camera's image plane.

Why not put the object(s) and a ruler on a scanner. That way no lens distortion is causing problems.
Import image in Sketchup - scale image, trace etc.
-
Excellent idea.
-
...Invert the tripod...Now that's a great idea and I hadn't thought of that; thanks Dave! Will try this one tomorrow (on work's time)
Kass- will also give the scanner idea a go. I have time to kill on the internet here, so I'll post tomorrow how things go

Had to check my tripod... I guess a $10 tripod is not decent.

Is this for visuals or production? If you're trying to make a seat for a tool I think Dave's process would work great.
For fun, you might try an app like this http://blenderartists.org/forum/showthread.php?319906-Turn-your-Android-Phone-into-a-3D-scanner-with-this-app on your phone to get the geometry.
