Hello!

I would like something that you probably have done it before so maybe is easy for you to give me some kind of tips..

I have printed fiducials on paper tape..

What I want to do is when I scroll the tape, to get an image scrolling too..

I am trying to figure out how can I map the fiducials on the image. Assume that the tape has 100 fiducials and 1 meter long(3 fts) and the image is about 2000 px width.

The screen is 400 px width. so no more than 4 fiducials can be present at any time..


A friend of mine tried to help me by telling me that I should calculate the distance the fiducials have from the x center of the screen , take the average and then scale/normalize it to 1..

I am not sure if I explained well what I want to do since I am not native English speaker and I do not know if I used the right words..

Thanks!
