There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.

If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

Best practices for good accuracy

I'm building an app which will allow users to place objects on the bottom side of a truck trailer. So the user starts in front of the truck and walks down a trench below the truck and scans the bottom of the truck. I'm using the Spatial Understanding for this.

When this is done the user has to define the point of origin of the coordinate system. The client wants this to be at the front of the truck in the middle at height of the road. Thus this point will float in the middle of the trench. I was thinking of placing a world anchor there.

Now the objects to be placed will be more than 5 meters away from that point of origin. From what I read it is not advisable to do this. What would be the best way to place holograms and maintain a high accuracy in relation to that point of origin.

To reiterate, I have to place objects in the world and need pretty accurate coordinates in relation to some arbitrary coordinate system with a point of origin that can be more than 5 meters away. Does anyone have experience with such a scenario and what the obvious obstacles are?

    I haven't used it but apparently Poster Calibration is the best solution for this. If you have seen the Ford videos online that is how they locked their Holograms to the vehicle.

  • @Ralph did you ever have any luck? I am working with the Poster Calibration but it is always a few centimeters off.
