3D Tracking with Android Cam API?

[b-g]

The recent post in #81 opendatacam/opendatacam#81 of the main repo made me wonder whether there is an API on Android to get z-depth infos for pixels via the in-built cam? Maybe we could have some rough 3d "thing" in Android out of the box?

There is an API : https://developers.google.com/ar/develop/java/depth/overview , that we would need to investigate.. I think it would affect performance quite a lot .. but yes definitely as a "opt-in" option .

would affect performance quite a lot

Not sure ... as if this all happens on dedicated chips outside of the normal CPU realm this might not be the case. From my back in day GPU OpenCV days it was sometimes counterintuitive what really affects performance a lot and what not.

Anyways was just an idea ... maybe we could the 3d tracking peeps to this once it is online/public and hope for PRs :)

yes true we never know before trying out 🙏 , I'm pessimistic sorry 😁
