QTvcp Cam View Dialog

LinuxCNC 2.8.0 Buster installed from iso

formerly we used CamPY with 2.7.14




linuxcnc.org/docs/2.8/html/gui/qtvcp_wid...ml#_camview_widget_2

2.4. Camview Widget
This is used to align the work piece or zero part features using a webcam.
It uses opencv vision library.





attempt with traditional AXIS works fine
[DISPLAY]
EMBED_TAB_NAME
EMBED_TAB_COMMAND=halcmd loadusr qtvcp –push_xid cam_align

it would be nice if a better prepared variant could be included in the release or if practical instructions for individual configuration could be documented

can I do something about it

try this:

EMBED_TAB_NAME= qtscreen
EMBED_TAB_COMMAND= halcmd loadusr -Wn qtvcp_embed qtvcp -d -c qtvcp_embed -x {XID} cam_align

thank you Chris, this works fine to embed it correct to the tab, and how can the size of the circle be adjusted, make it more and less large? Peter

I use a laptop to test - I hope a mouse will be the same.
button1 + scroll = zoom
button 2 + scroll = rotate cross
button 3 + scroll ( or button 1+2 + scroll) = circle diameter.

If you want the set origin and go to origin buttons to work you must add MDI monnads to the INI
something like this:

[MDI_COMMAND_LIST]
MDI_COMMAND = G10 L20 P0 X0Y0
MDI_COMMAND = G0x0y0z0

Chris, this is high tech, absolutely perfectly finished, thank you for all that great work!

Great! let me know if there are improvements that could be added.
I think it's pretty useful as is though.

of course, I will gladly reproduce my usual usage procedures here, as soon as possible

Chris, I see OpenCV has edge and corner detection. How could the opencv library be used to automatically find the edges and corners of a sheet of material placed on a plasma table? The intent would be to wander around on its own and discover the 0,0 corner and then rotate X & Y coordinates around Z. An 8' x 12 ' 3/4" sheet of steel is pretty heavy so its not really feasible to align the sheet perfectly.

Now that would be a cool improvement!

IIRC samco had a python opencv program to search for holes. i wonder if he still has it...
