Mirror ImageTarget

August 8, 2017 - 12:47am #1

Hello, everyone!

I had an AR demo that use an ImageTarget. It can recognize one picture and show a model. Now, I found that the demo can not recognize the picture in the mirror.Why? The picture.jpg is the original picture and the picture-mirror.jpg is the picture in the mirror.

The only way to do this would be to create a second Image Target that is a mirrored version of the original. Software like Photoshop and Gimp have tools that can mirror images in this way.

Hello, Strasza.

Is there any way to achieve this idea? For example, add a mirror shader plane?

Hello FounderEdu,

When you look at the image through a mirror, the resulting image has all of its features flipped. Vuforia is using the location of these features to detect and track the target, so flipping them to the opposite side changes the features' locations and will prevent tracking on the original Image Target. You can read more about features and image rating here https://library.vuforia.com/articles/Solution/Optimizing-Target-Detection-and-Tracking-Stability.html#natural

Thanks,
