public static final enumSession.FeatureMapQuality
Indicates the quality of the visual features seen by ARCore in the preceding few seconds from a
given cameraPose. A higher quality indicates a Cloud Anchor hosted at the current time
with the current set of recently seen feature points will generally be easier to resolve more
accurately. See theCloud
Anchors developer guidefor more information.

The quality of features seen from the pose in the preceding few seconds is likely sufficient
for ARCore to successfullyresolvea Cloud Anchor

Session.FeatureMapQuality
INSUFFICIENT
The quality of features seen from the pose in the preceding few seconds is low. This state
indicates that ARCore will likely have more difficultyresolvingthe Cloud Anchor. Encourage the user to move the device, so that the desired
position of the Cloud Anchor to be hosted is seen from different angles.
