Hi there!
I’m having this problem, using MTmini package 1, when i calibrate everything works, blobs are detected, and tracked correctly, the problem is, that when I run one of the demos like Smoke_Demo, it only uses one portion of the window, not the whole window, and same situation happens with the Flash Demos…

Anyone having this issue too?
Any suggestions?

Thanks

As I see it, you are running at different resolutions when you’re calibrating than when you run the demo apps. Try to set the same resolution at the camera driver and the configuration process for touchlib. Also remember, is always preferable a high fps value than a high resolution image.

Yes, I’ve tried with 4:3 resolutions (1024x768, 800,600, 640x480), as well as my default 16:9 resolution (1280x800), doing it all again, calibrating using those screen resolutions.
And I forgot to say that the camera avilable resolutions I use, are 640x480 and 352x288

I´m not talking about your screen resolution. When you first launch the configApp it ask you to set the camera native resolution; it means that you have to set the same resolution you have set as native at the camera driver (or any app that manage the camera driver, like “Quick Capture” or “Webcam Center” for example) and that depends on your camera model-brand.

Oh yeah, sure, I’ve tried with all of the available resolutions, and no one works, but I think I found a way to kinda “magnify” the blob events, I mean insted of a X:100,Y:200, something like X:150,Y:300, the only way I found to do this was editing de configapp.xml file, changing the lrX and the lrY attributes from 1.000000 to 1.500000 and seems to work, but the problem now is that with this trick, I’m losing image precision, at least I’m not losing FPS!
