Are results from FeatureTracker on the left and right camera synchronized?

Dong_Liu

I mean does the same feature on the left and right camera have the same id?

I'm using two FeatureTracker nodes to track right and left camera. Just like the feature_tracker example.

If not, is there a way to archive it?

Thanks!

No, they are not. Each instance of each node is independent from the other.
Not possible to match features from one frame to other, at the moment we don't have feature descriptors implemented, but we have it on our roadmap ORB feature descriptors. CC: @luxonis-Sachin on that.
After we have feature descriptors it will be possible to match features from one camera frame to the other.

Dong_Liu Here are some of the comments where some users suggested using learning-based feature descriptors for this task or Use OpenCL based implementation to run it on the device.

Thanks very much!

[unknown] no, it's not a feature that we are planning to add.
