observing target points

July 11, 2017 - 9:41pm #1

Hi all,

Does anyone have experience in observing, and tracking how many target points have been recognized and tracked within the image target?

I am trying to hold off displaying image target child objects until ALL target points within the image target have been recognized.



If points A, B, C, D, & E have been tracked, then...

Display ImageTarget child objects (model)


as apposed to


Vuforia recognizing the ImageTarget with points A, C, & E then...

displaying the Image Target child objects.


Ideally I would also like to display how many points have been tracked with some UI text.


I guess multi-targets sound like something that would work, however I want each target within a 2d image, not different sides of a 3d object.


Can I load multiple image targets (which are actually just parts of an overall larger image) and arrange them on different Image Targets, side by side?


Any help or advice on the best way to do this would be appreciated.

Hello lujo76,

You can use Multi-Targets for multiple, flat images. You can do this by modifying the xml file that is associated with a Multi-Target. This file is located in Assets/StreamingAssets/QCAR/ and has rotation and translation values for all the sections of a Multi-Target. Modify these to achieve the shape you want to detect for you app.
