March 26, 2011 - 12:56am #1

Hi bros, in web page, u write there are 512 frame marker in the folder media/, but when i get into it, i only find 2 files: target_marker_A4.pdf, target_marker_USLetter.pdf, where the zip or rar file that containing all the kind of marker u mentioned about?
The second question is: what is the maximum size i can enlarge the frame marker size so i can put my own image inside this marker, i read ur web, its size must be form 3-10 cm.is it right or be possible to enlarge more?

Look in the "assets" folder in the top level of the qcar-sdk directory. There should be a frame-markers.zip file, this contains all 512 markers. You will want to scale up the markers using nearest-neighbor resampling to keep the edges sharp.

You can play around with different frame marker sizes, but keep in mind that the camera needs the entire frame marker in view to track it (unlike image targets, where a partial view is enough for tracking).
