Red and Yellow color detection using a webcam

[Abook7]

hi, I have been working on a project that detects red and yellow color, i have worked on the program at the labs and when i tried to open the Vi, file at home it didnt open for me the required palletes. I gave me question marks instead, and it keeps searching for these Vi's: 

IMAQ Color lean.vi

IMAQ USB close.vi

IMAQ USB grab Acquire.vi

IMAQ USB grab Setup.vi

IMAQ USB Init.vi

IMAQ USB Enumerate Cameras.vi

SHould i install an addtional software of driver?...whats the problem?

Thanks

These are pard of the vision development (or at least vision acquisition) module it has to be installed after labview and liscenced seperatly (you can isntall and use usually for 30days in demo mode)

I have installed the newest version of vision aquisition software, but still i cand find the palletes for IMAQ USB Camera? Is there an additional driver?

Hi Abook,

your program is using the old version of Vision Acquisition Software that didn't support DirectShow USB cameras, and the USB driver had to be installed separately.

Anyway I would suggest you to install the newest VAS and change the old VIs to the new ones.

Best regards,

I have already downloaded this driver but its still not working, no palletes of  IMAQ usb are avaible when i open the program. I read the comments in the link and some of them say that its not compatible with windows 7....I have windows 7 and labview 2011,  should i have an older version to make it work?

Using the newer ImaqDX is very easy to use, I have communicated with several webcams with no problem,  sorry I didnt realize you were using an old IMAQ palette

[Abook7]

should i replace the palletes in the vi that i uploaded previously with IMAQdx palletes?...I read somewhere that there should be subvi's called:

IMAQ Color lean.vi

IMAQ USB close.vi

IMAQ USB grab Acquire.vi

IMAQ USB grab Setup.vi

IMAQ USB Init.vi

IMAQ USB Enumerate Cameras.vi

doesnt it differ between IMAQ grab Acquire and IMAQ USB grab Acquire and the others...?

Dear Abook,

you can replace the VIs, but not with IMAQ but IMAQdx VIs. It would also probably require some modifications.

Anyway, if you installed the old USB driver, LabVIEW should find the VIs even though they probably won't appear properly in the new LabVIEW pallettes. When you open the VI, doesn't LabVIEW search for the IMAQ USB functions?

I hope to be useful for detection after getting color image must be converted in the imegen 32bits 8bits the camera on, then do a color filter, removing particles, there is a similar example in the browser examples examples LabVIEW provides the program: Help / search example
