Using ImageTargets with variable target size

October 11, 2018 - 4:44am #1

Hi,

I'm developing a Hololens app using the ImageTargets functionality from Vuforia to detect a TV screen showing the target image. My problem is that because ImageTargets requires you to define the expected size of the image, but when the TV displays the image, the holograms that are subsequently created do not always align with where the screen is because different screens will display the image at different sizes, and so Vuforia interprets this as the image being closer or further away than it actually is. This wouldn't be a problem if I was using a computer monitor, as I could get the image displayed at a defined size, but TV screens are unable to do this. Does anyone have any ideas on a workaround for this problem?

Thanks,

O

You could try to calculate the difference in resolution between your computer monitor and TV and resize your image target by that factor
