    Measure object with webcam

    Does anyone know if this is possible? Measuring an object with webcam? Getting it's length, width and height?

    Well, it must be theoretically possible if you can know the distance of the object from the webcam...

    I think this might be difficult, particularly to get all three dimensions of a solid object (might need two cams with overlapping field); also you would probably need some sort of calibration scale in the background to distinguish close/small from distant/large objects.

    Anyhow this programming library is free to use and runs on Linux:

    Mathematically possible if you have two cameras, or (I think) if you rotate the object, but programmatically difficult.
