Hi,

For a small project, we are looking for a medium-quality web-cam that it could be used in a fully manual. We should be able to take over exposure time, gain, white-balance and other properties using openCV. Having tried out about a half-dozen web-cams, we are not yet able to identify one.

Any experience, suggestions would be appreciated.

Thanks,

hi @Shivam ;) if i understand the post correctly, he's asking for a recommendation, what to buy.

cv is a total pita, if you can't disable/control things like whitebalance or autofocus from the actual program.

Indeed, I am looking for recommendations to buy. Since this is for a scientific measurement, we would like to be able to control whitebalance, autofocus etc.

btw, apart from the usual capture.set(CV_CAP_PROP_*) things, with a bit of luck, you can access the driver page and set things there :

cap.set(CAP_PROP_SETTINGS,1);

There are several models from econ systems which are uvc compliant. The 5-MP USB Cam gives you the full control using UVC. The USB 3.0 Models bring there own library to control them. http://www.e-consystems.com/default-de.asp

Point Grey (a Canadian company) offers several possibly-applicable products. They are not cheap, but are intended for vision applications and include API for "manual" settings.

Thanks.That is bit of an overkill for our application but it is a good point to go look at scientific camera manufacturers to see if there are any lowcost options.
