Ground Plane enabled on Image Target

January 3, 2022 - 2:21am #1

Hello, I am building an app with AR where the user will be able to see some small scenes in front of images. I will have 12 images and I want to use Image Target in order to enable each scene. Although I have noticed that Image Target is a little bit shaky and that causes visual problems. On the other hand Ground Plane seems to be more stable. So my idea is to use Image Target so the app can understand in front of which of the 12 images is standing and then use Ground Plane to scan the area in front of the image and play the particular scene. Each image will have some space (1m*1m) in front of them so the scenes can be played. Any idea on how I can do it? I would also like to learn if I can add some limits in the Ground Plane so the scene can only be enabled in front of the image and not far from it. So it is like having Image Target but using Ground Plane so the result can be more stable.

Image Target detected -> Ground Plane detects the space in front of the image -> Scene Played in front of the image

Thank you in advance!

Hey there,

 

Does using the Ground Plane and Image Targets not work?

Still would be interested in knowing how to combine Image Target with Ground Plane as described, that seems to be a very interesting approach.

Thanks for the support team feedback on this.

Hey there,

 

First of all, I suggest making sure that the width you set when adding the image targets to the target manager is the exact same width (in meters) in the real world. Having a wrong width can cause the marker to be inaccurately displayed and more 'shaky'.

Did you also make sure to enable the 'Track Device Pose' option in the configuration file? This provides additional robustness to your target tracking. You can find more information about that here: https://library.vuforia.com/device-tracking/enable-device-tracking-unity

Another solution would be to make the image targets larger, so it's easier to keep tracking them to offer the user the best tracking quality.

Hope that helps a little!
