The answer to that is: It depends.
You can run barcode detection at 30fps on a 1080p video using any modern PC, no problem at all.
But high performance industrial barcode scanners have certain features that would be undesirable in any other application. A greyscale-only sensor for maximum sensitivity, jittery autofocus and autoexposure to respond fast when something appears right in front of the lens, autofocus switching attention so everything in view gets a chance at being in focus, built-in illumination to help avoid motion blur, and so on.
So although the software can provide a good framerate, a laptop webcam may still perform worse than a dedicated barcode scanner.
(zbar is a mixture of good and bad - if you want to experience software barcode detection for yourself your phone's app store probably offers 'scandit' which is closed source but performs pretty well)
- PaulHoule 3y agoLaptop cameras seem to be about 20 years behind cell phone cameras in image quality, my experience is that it’s almost certain that the camera in a PC laptop burns out in 2 years. I’ve had them go bad in macbooks too but I think they hold up better. I’ve never seen a mobile device camera fail without the device failing completely.
- nolongerthere 3y agoWow, I don’t think I’ve ever experienced a camera burning out on any device, I wonder what you’re skiing with your laptop camera that its burning out so quickly
