I have some wooden cut out panels. I need to build an exact scale plan of them in illustrator or photoshop, so that I can create some artwork to be printed on vinyl.

I don’t have a scanner, and the shapes are quite complex, with some holes in (not just a rectangle).

My plan was to take a photo from directly above, then import this into a photoshop or illustrator document, measuring one edge of the object to get the scale right.

When I do this, there is lens distortion and the perspective on the cutouts looks wrong, because the wooden cutout is about 1.5cm deep- so eg the holes are cylinders and you can see the sides of the walls.

What’s the best way to do this? If I draw round the wooden shape, then measure it all? Scan it using my phone’s camera? Is photoshop or illustrator the best tool for this?
