Can OpenCV be utilized to take dimensions of a shipping package
We are trying to simplify the measurements of shipping packages for UPS & Fedex. Can OpenCV use an image to calculate Length Width and Height of a package from an image taken on a Android Device?
it's nothing special to opencv, but with a single (calibrated) camera, you can only calculate the size of an object, if you know the distance (and vice versa). see pinhole model
Thanks is there an existing program that does this that I can tap into?
no idea, sorry. how do you plan to solve above problem ?
opencv can help you with the calibration, and with finding the (pixel) contours of your target.
(next problem is: after a calibration, you must not change the focus, ever, which might be almost impossible on a phone, where you can't control that)
So my thoughts would be to have a stationary camera on a pole over the Shipping Scale that would take the exact same photo from the exact same distance every time. If I can have a program that would calculate the dimensions then I could record it in our web based system which would be good enough... Just need the program ..lol Any help is greatly appreciated
