I'm going crazy with cylindrical image target.

I read the Vuforia doc about how to calculate ratio but I need to have a sample made with numbers...

Then, for example, I have a bottle coke, I enter Top = 6.5 Bottom 6.5 and Height 11. My image is 529 x 530.

In the doc I read

W = PiGreco bottom H = sL

so, W = PiGreco 529 = 168 and H = 530

It's right? But rescaling the image Vuforia still says the ratio is not right.

Please, someone can help me? Thanks

The aspect ratio of your image has to match what is expected based on the target Physical dimensions. In the coke case the image ratio

W/H = PI * 6.5 / 11.0 = 1.85

for example if the image has H = 530 pixels, then

W = 1.85 * H = 1.85 * 530 = 980
