how to i get the reconstruction script(s) to work with my depth images?

### My Question

Hello, i am trying to use the reconstruction scripts to generate point clouds/meshs from the depth output obtained from [consistent depth estimation](https://github.com/facebookresearch/consistent_depth)

i keep getting an error from run_system.py for "unsupported image format"

RuntimeError: [Open3D Error] (static std::shared_ptr open3d::geometry::RGBDImage::CreateFromColorAndDepth(const open3d::geometry::Image&, const open3d::geometry::Image&, double, double, bool)) /root/Open3D/cpp/open3d/geometry/RGBDImageFactory.cpp:42: [CreateFromColorAndDepth] Unsupported image format.

i was trying to use greyscaled version of the output from the neural network.

i tried changing the channel count of the depth map to uint16.

this is my dataset with the original images, original depth output and the greyscaled depth images.

transform.json is the camera intristic from COLMAP used in the training and config.json is the same as the example config in the documentation but with the paths changed
