Hi Team,

How to auto find a stable enough ground plane and spawn a anchor after the ground plane is stable.

As check the vuforia ground plane demo, it need place some flat position manually then show model.

Hello,

Due to the nature of the technology, Ground Plane may not be able to provide 6DoF tracking in all environments. This article includes some information for an ideal Ground Plane environment: https://library.vuforia.com/articles/Training/ground-plane-guide.html



Specifically, the following is relevant to this issue:

Ground Plane utilizes images from the device camera to understand the basic geometry of your environment. Therefore it is necessary to stage Ground Plane experiences in settings that enable the camera to accurately capture the details of the surroundings. 

Recommendations:

  • Stable lighting conditions
  • Moderate lighting - not too bright or too dark
  • Avoid glare and dark shadows
  • Surface details help to reveal geometry and improve accuracy and performance

We've found that in areas with low detail surfaces we were able to improve the experience by taking additional time to scan the environment before performing the first hit test. While not guaranteed to work, I was able to perform 6DoF/positional tracking in a wide variety of environments such as low detail carpet, tiles, and pavement.



The basic thought is that the more information the system has from environment scanning (floors, table tops, etc.), the more likely you are to gain a 6DoF pose.

Thanks,

Vuforia Support
