Title: Video Window plugin Issues
Post by: dandumit on April 06, 2008, 05:38:05 AM

Hi,
I have mounted an web cam next to spindles to ease the finding of x0 and y0 coordinates.
I have found the following :

A. critical issues :
- image mirrored on X axis
- on mouse move the movement on Y axis is inverted

B. issues acceptable for a while :
- some times the arrow keys are not working
- when you check the mouse move the arrow keys are not working also
- doesn't remember scale settings

I have made a small video of my trials :

Is any updated version available ? Does anybody has available the source code for this plug-in I would like to try to enhance it.

Regards,
Daniel

I'll let the lads on the hill answer that one - only to say there are one or two issues with the USB cameras.

The main problem seems to be with those cameras that plug in and use the Windows drivers, rather than have their own

Thanks for answer.
I have tried to find some work arounds . I have found that along with the webcam it comes a small view program wich has various settings options. In this prog the image is displayed wright.
And I have found that if I mirror the image on X axis on that prog , after that in Mach it will appear correctly.
It still remains the main issue of inverted move on Y axis and of course the remaining issues.

My mistake :
I was running Version R2.47 of Mach.
in the latest version : 2.63 it's working nice.
however I will try to make a small enhancement of this in order to add some offset values when the webcam is aside from drill.
