Vuforia Cylindrical Target

May 25, 2016 - 6:13am #1

Hi i am making a cylindrical target for one of my project. I create the target as Cylinder of bottom and top diameter of 3.835 and side length of 12.042.

And when i upload target image size image of resolution 867 * 289 getting error of ''image does not the match the dimensions of cylinder target. The ratio of the width to the height of this image should be 1.000". should i change the size of diameter and side length. Any help please...? For reference i added screen shots also.

Hello,

Yes, you are correct. Getting the proper ratios for cylinder targets can be a bit tricky and may require some experimentation.

I've looked more closely at your assets and have noticed that the bottom/top diameter to side length ratio (~1:4) is very different from your image's aspect ratio (3:1). Ideally, these should be equivalent (i.e. 1.000). I use a ratio calculator: http://andrew.hedges.name/experiments/aspect_ratio/ to help me determine scene heights and widths for cylinder targets.

Thanks, Dave
