Hello everyone.

The Mixed Reality Forums here are no longer being used or maintained.

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.

And always feel free to hit us up on Twitter @MxdRealityDev.

What should hololens calibration do?Which expert has the hololens calibration app?Thank you

The project I am working on is measuring the registration error of augmented reality, First need to do the calibration of hololens, but, the specific method of hololens calibration has not been found on the official website or in the manual.

Hololens calibration is to calculate the projection matrix M by calculating the correspondence between a point in the world coordinate system and the pixel coordinate system, including internal parameter matrix M1 and external parameter matrix M2. The matrix M2=[R|t], where t is the position of the hololens camera in the world coordinate system, and R is the direction of the hololens camera in the world coordinate system. The error between the calculated and true values of R and t can be obtained by hololens calibration.

The Hololens internal computer has already done this process and applied the resulting data to the actual operation. This is the basic principle of hololens. My topic asked me to restore this process again, get the data from the hololens calibration and find the calibration error.

I would like to know which expert can provide a solution or calibration algorithm/app to help me get data and errors through calibration. Can also be paid, thank you very much.
