Known issue: Vuforia 7.5.26 does work with .NET scripting backend on UWP in Unity

October 31, 2018 - 8:57am #1

Hello,

A regression was introduced with Vuforia SDK 7.5.26 in Unity where using the .NET scripting backend will throw an exception when running a Universal Windows Platform build. This also includes HoloLens apps.

Please use the IL2CPP scripting backend instead, where this issue is not seen. We plan to fix this issue in an upcoming release.

Updated HoloLens resolution now available

March 21, 2017 - 9:39am #1

Hello,

A patch is available for HoloLens performance modes for Vuforia SDK 6.1 and greater. This change updates the "MODE_DEFAULT" camera device/performance mode to use the 896x504 resolution, as recommended by Microsoft for Vuforia computer vision algorithms. Vuforia's testing shows an improvement in detection distances on HoloLens when using this mode. The previous MODE_DEFAULT resolution can still be used by selecting MODE_OPTIMIZE_SPEED (1280X720). MODE_OPTIMIZE_QUALITY (1344x756) remains unchanged.

Hololens 2 and image target

January 17, 2020 - 7:06am #1

What is the smallest size of the image that Hololens 2 can track? I am trying with image target of size width: 0.0565 and height: 0.04725 (unity unit) and it doesn't work. Don't have bigger flat surface on the object to make the target larger.

The same image target works great on Hololens 1 and vuforia image target version 6-2-10 in Unity 5.6.

Do I miss anything? Thank you

There is a solution for the case where the model deviates from the camera in hololens

January 7, 2020 - 5:50am #1

If your hololens model deviates from the camera, hopefully my solution will help.

The possible reason for this is that the size of the graph you are using for identification is not the same in the program as it is in reality.To make sure you don't have to print the recognition image first, just run the vuforia program and adjust the size of the recognition image on your computer. You can easily see what's going on.

I really hope it helps because I've wasted so much time on it.

'StatusChangeResult' does not exist in the type 'TrackableBehaviour'

December 17, 2019 - 3:03am #1

I followed the official guide how to setup Vuforia with HoloLens. I'm using Unity 2019.21f1. 

After downloading the HoloLens Vuforia Sample I get a bunch of errors. I have to go manually to package manager and download Vuforia Engine, in this case 8.5.9.



HoloLens vuforia example is 8.6.7.



After I install it I get one error:
