Parameters of stationary cameras

[keqizero]

Hi, thank you for the great work!

I have a question about the dataset: are the intrinsic and extrinsic parameters of the stationary cameras provided? I didn't find them after downloading.

Thanks!

Yes. We provide the colmap reconstruction - this includes stationary camera parameters.

You can find them being loaded here -

• egohumans/egohumans/lib/datasets/exo_camera.py

  Line 44 in d7875dd

  self.intrinsics = self.reconstruction.cameras[self.colmap_camera_id]

• egohumans/egohumans/lib/datasets/exo_camera.py

  Line 109 in d7875dd

  self.extrinsics = np.dot(self.raw_extrinsics, self.coordinate_transform)

You can invoke this by calling any of the scripts (eg. visualize) which uses the stationary camera.
