Above is a prototype of creating a cut preview for your GCODE of where it will cut (On a MillRight CNC machine!!), by simply taking a picture of the CNC bed with your wood on bed. I spend so much time trying to line up the machine with my work piece, making sure it won't intersect my clamps. Sometimes I hit my clamps, sometimes my bit goes off the workpiece or hits a soft limit, stopping my cut process.
If you like the idea, think it could help, lmk, or like the video. My time is pretty limited with kids and would love to polish it more myself or with community help.

I think this is one of the best ideas I have seen and heard of in a long time. I think you really are on to something.

Thanks! I'm not sure what will come of the idea yet. I'm happy to let anyone go with it....This is certainly just in the prototype phase at the moment.

Wow! tliechty, you have taken the CNC visual layout to the 3D level and process ! Well done ! I think you are on to something easy to use.
LightBurn has a 2D version of "tools/features" like this for laser process, I encourage you to check it out if not familiar with it.
I like your design in that unlike LB, your system seems to self "register/align" the camera to the work area via the homography transform in your code. If I understand that right, this makes the precise camera position less permanent and thus less subject to bumps and jarring its sure to encounter over time while stationed above a dirty CNC work area. The absence of this design in LB is the exact reason I have not bothered with adding a work area camera to my CNC, rather I use old school WCS offsets with 000 in a corner or known position of my work piece.
Just curious, what is the level of accuracy (1mm or less I hope) for the 2D and 3D homography transform given the camera perspective above the work area ?
Nice work. Please keep us posted on progress and if trials become available.
