New feature: Geo-positioned AR Object

[rlazom]

The idea of this new feature is to place an object on a given geocoordinates an show it in the ARCoreView when the user points the camera in this position.

Could be convenient also take into account the minimum distance to show the object.
Thanks

I've worked on it for a few days and managed to get something that works.
I need further testing though !

Here is how I've done it:

ARCore coord system is different each time. This is the main challenge when working on geo-positioned AR object.
Basically, we need to find the true north at a starting point for placing everything.

• Convert the GPS coord (lat/long) to cartesian coord (look at UTM)
• Calculate the coord in the local system (AR core) using the difference between the device UTM coord and the object UTM coord
• Calculate the rotation using the new position and the azimuth angle:
  The idea is to get the azimuth angle from the north using sensors or the flutter_compass package (not the true north but it seems to work)
• Convert the X,Y,Z rotation you've calculate before to a quaternion (because AR Core rotations use quaternion)
• Finally, add the AnchorNode with the position and rotation calculated before to the scene

tips: add it when the user tap a plane, so the calibration is good before it adds the object

Hi, Can you share some sample code?

Hello @RobinLbt I'm also interested in a geopositioned object view. I would like to use it as the basis for a team project at my university.

I am also interested on the GPS implementation for a project that I run.

Any solution guys?
