I'm interested in doing large scale AR projects and wondered how large an image target can get. I'm working under the assumption that it's best to work on a 1 to 1 scale with an image target. What i mean is, if I make an image target that is a standard letter size image, 8.5 x 11, then it's best to use an 8.5 x 11 print out as the image target. However, how much can I scale the print out up or down and it still works as an image target?
Also, I noticed that there is a file size limit of 2.4 mgs that I can upload to make an image target. In order to balance the quality of the image for print and the size of the image target, I've been able to make a 11 x 17 image target print.
So, my main question is, given the file size upload limit, how large can I scale up my 11 x 17 before it starts to break down the image target data set? I'm looking at ways to AR large posters sized prints.
Or, am I looking at this the wrong way? Any numbers explaining the limits of the size of image targets would be greatly appreciated.
