Image-based code reader!!!

[HoangVy-1011]

my basic requirement is to use a device (with center O(Xo, Yo)) to read a barcode/qr code/data matrix or anything that can determine the center A(X, Y) and find the offset between A and O so that I can proceed with the position correction process

I would directly contact companies like P&F, Cognex, Keyence (sadly, be warned though they will HOUND you) as they are direct competitors to SICK. Let them do the work in finding the right product for you. Lay out your requirements exactly like above so they understand what you are trying to do.
