Shaking issue and extended tracking with Tango.

By Strasza on Thu, 10/12/2017 - 16:54

Hello everyone,

I am trying to implement "Vuforia support for Tango" feature of Vuforia 6.5 in Unity 2017.2.0f2 for Lenovo PHAB 2 Pro (Android 6.0.1 "Marshmallow"), my project contains one ImageTarget object with enabled "Extended Tracking" (world center mode: "DEVICE_TRACKING", using device pose tracking, tracking mode: "POSITIONAL").

Extended tracking with the depth sensor works stable, but if the smartphole camera is looking directly at the Marker or its part (especially at a distance of about 30-40 centimeters) virtual augmentet objects are shaking. My image has а star rating of five.

Is there any solution to prevent this prolem or to select "EXTENDED_TRACKED" status of the marker manually (for example, after one second in a "TRACKED" status) when the marker can be detected but does not affect the position of augmented objects automatically? The ImageTarget is not supposed to move.

Thank you in advance!
