Device tracking is not working if FusionProviderType is VISION_ONLY?

By medabit on Thu, 07/21/2022 - 17:34

My final goal is to develop an android app and android phone connect AR glasses with camera and IMU.

Use the camera on the android phone (FusionProviderType is SENSOR_FUSION and PLATFORM_SENSOR_FUSION), the device pose that can be taken normally (VuforiaBehaviour.Instance.transform.eulerAngles and VuforiaBehaviour.Instance.transform.position will change).

Then I follow this to use an external camera from AR glasses. I can get camera image from external camera and FusionProviderType will be VISION_ONLY, but VuforiaBehaviour.Instance.transform.eulerAngles and VuforiaBehaviour.Instance.transform.position nerver changed.

Then I tried to use webcam on windows(UWP), and FusionProviderType is VISION_ONLY. VuforiaBehaviour.Instance.transform.eulerAngles and VuforiaBehaviour.Instance.transform.position still nerver changed. How to get device post in VISION_ONLY mode?

Hello,

Have you reviewed our File Driver sample? Per the following library article, this sample "... demonstrates how to access image and pose data from external systems."
