Hololens 3d object tracking issue - not working

February 15, 2017 - 9:25am #1

Hi!

I am developing a simple app for Hololens with 3d object recognition. I have scanned an object and created a database in target manager section in my developer account.

Prerequisites:

- Vuforia SDK for Unity 3d;

- Unity 5.5.1f1;

- scanned 3d object database available in Unity project.

I ran object recognition in Unity editor with my web camera and it works fine - object is recognized.

Issue: when I run the project in Hololens - object recognition does not work.

Trackable id is: 11111.

My logs on Hololens attached.

There is a message in logs: Missing Database.

Is there any special procedure to place Vuforia database somewhere?

Thanks for any help.

Oleksii

Hololens 3d object tracking issue - not working

October 29, 2019 - 2:33am #7

Hey,

did you get it working on Hololens? I am facing the same behaviour. My object is recognized quickly with the android smartphone and Vuforia object detection but not with the HoloLens.

Can someone help me?

 

Regards,

Hello,

It would be helpful to understand the types of objects you are trying to detect. Can you post pictures?

Thanks

Hololens 3d object tracking issue - not working

We are also deployed the project into hololens to track the 3D models.

 

But its very hard to detect with Hololens. Very rarely it is recognizing. 

 

Is there any additional techniques to improve the quality of tracking in hololens ? 

 

Thanks in advance .....

Hi,

Thank you for reply.

We have alreay tested on Android and 3d object recorgnition works fine on that platform. It also works fine from Windows Unity editor. 

In the same time, I steel need this functionality to start working on Hololens, as it is stated by Vuforia.

Here is an example of demo I want to run:

Hello,

I don't believe the missing database message is related to your issue as it detected in play mode.

I would suggest trying to run it on a mobile device.

Thanks
