Metadata asset #3

Hi Keijiro,

I'm using your repo to make some effects on Depthkit footage from azure. I'm guessing your Metadata.asset file is from Kinect V2, as your depth image resolution is 512*424. I'm trying to copy the parameters from Azure into a new Medata file. Depthkit conversion gives a metadata file from which I can copy:

from lines 18 to 24 of the Metadata scriptable object: `

        material.SetVector("_Crop", pers.crop);
        material.SetVector("_ImageDimensions", pers.depthImageSize);
        material.SetVector("_FocalLength", pers.depthFocalLength);
        material.SetVector("_PrincipalPoint", pers.depthPrincipalPoint);
        material.SetFloat("_NearClip", pers.nearClip);
        material.SetFloat("_FarClip", pers.farClip);
        material.SetMatrix("_Extrinsics", pers.extrinsics);

`

Therefore, I'm missing extrinsics and crop. How would I get them? (I tried using depthkit's sensor calibration json file, but their extrinsic values are not in matrix form).

Best,

Sergio

You can convert a metadata file (a .txt file exported from Depthkit along with a .mp4 file) from right click menu ("Depthkit" -> "Convert Metadata").

Sorry for lack of proper instructions.
