thanks, thanks, thanks.

Wow, very cool!
Thank you Alex!

But now I still need a “multicam driver for dummies"-guide, because I don’t know, how to use it. :-(
Will there be a simple installer in the near future?

Hi AlexP,
Little bit off topic just if you know if there is a way to pull out frame rate signal from the ps3Eye for syncing so be able to use it as an interrupt signal for IR amplifier hardware.

Goran

Yes there is. You could use the VSYNC output from the pin C6 of the OV7220 sensor chip. You must be careful since this is a 3.3V digital output pin that should be buffered before you can drive your external circuitry. Another pin of interest here is the FSIN (A4) pin. This could be used to synchronize the frame capture.

Yes, I am working on making the installer for this version of the driver. It will also include the VS2008 project for the camera demo app.
I am also working on integrating this into the latest CCV.
Stay tuned.

great work as always Alex
your the man

cool, tried out the multicamTest app and it works like a charm

wanted to work on integrating it into CCV but will wait for your update!

you are awesome dude! Congratulations for all the hard work you have done!

Thanks for all your hard work Alex

Alex, this is very cool that you keep releasing these updates!

I know this is aimed at the MT community primarily, which is why you handle all the stitching and lens correction etc. automatically. But I’d really like to just use two color cameras, polling the image streams asynchronously.

Is there any chance of a color version that is more like the single cam driver, but just, say, adds a “which camera” parameter to all the functions?

Also, it’s great to see that you used c-style exports here! More of that please

Hi Again Alex,

I compiled your PS3EyeMultiCam Test App source code and it works perfectly with 2 cameras. I’’m so happy with it its going to open a lot of new doors to people

I can’t get it to detect any more of my connected cameras. Is there anything specific that I should be doin with the multicam driver in order to install it and get it working? I am assuming that the cameras are probably using the old Ps3Eye driver still....or does the multicam driver actually support more than 2 cameras?

Sorry if I sound silly

Thanks for your help,
Alan

Gunning: I’m pretty sure this is allows for 2 cameras max.

kylemcdonald: I agree. It would be nice to have a version that doesn’t have the bells and whistles and just allows the ability to access more than one camera. I’m not sure it’s ideal to only be able to use 2 cameras stitched together.

2 questions- how do u use the driver, and were would i get one of those octopus thiongs u used?

Any ideas on porting this to OSx?

Thanks Alex for the answer it will be very helpful

See you around…

Seth: Thanks for the Reply This is a pity, I thought that it was just a limitation on the part of the test software and not the multicam driver itself…

While this multicam driver is aimed mainly at the MT group its uses would be wide spread out side also, it would be really great if you could simply access more than 2 cameras and control the stitching operation through openCV

For my own testing I was hoping to stitch together the color video instead of greyscale.
I tried changing the No. colour Channels to 3 and the Video Depth in the openCV function cvCreateImage(cvSize(w,h), IPL_DEPTH_8U, 1);
but the stiched video keeps apearring greyscale, is there anywhere else in the test code or PS3EyeMulticamStart() function that is converts it to greyscale?
