Image Tracking malfunctioning after update to Vuforia 10

By nohodublin on Fri, 10/21/2022 - 14:54

I've had to update a project in Unity to use Vuforia 10 as Google now require API 31 for publishing apps and Vuforia 9.8 was crashing the app when building with API 31 support.  Since the update one of our image tracking targets is malfunctioning. When it is tracked the AR content is spawning on its side rather than standing as it should. It also appears to be offset from its intended position, though its hard to be certain with the odd rotation of the AR model.  This is only happening with one of our three tracking images and the issue wasn't present with the previous version of Vuforia. Has anyone encountered anything similar?  I can't replace the tracking image as it has already been printed and embedded in a plinth on site so I'd appreciate any help available. 

Thank you to anyone with any advice.

I also updated my Vuforia version recently and some QR codes I used as image targets on Vuforia 9.8.8 perform pretty bad at Vuforia 10. They are reeealy slow to detect. I needed to change for new ones with more details to finish my project.

Hey there,

 

Sadly I would say that QR-codes are against our best practices and therefor the bad experience of detection and tracking is expected. This is due to the repetitive patterns of the QR codes. 

 

Kind regards,
