maybe i'm being [very] naive here, but, is the idea of a low cost laser scanner a pipe dream?? what i envision would/could? contain a few basic parts:
1) laser source (? spinning laser pointer type device to create a 'line' of light - aperture to focus light on required surface)
2) video camera (? filtered to just 'see' the laser light and set at an angle so as to see the surface contour 'curve')
3) screen grabber board on PC (would 'grab' the image of the contour of the object (foot in my case) at preset intervals of time)
4) CAD software (to assemble these curves into a solid model and then alter the image as required)
5) CNC mill ( to mill the finished/corrected model)
There are laser scanners out on the market, but they are expensive - this thing could be on the small side because you (I) would just be scanning a surface the size of the bottom of your foot.
Would love to hear comments
