About bundle_adjust and dsmr package #1

Closed LHDuan closed 2 years ago

LHDuan commented 2 years ago

Thanks for your excellent work. I have some problems with the package installation.

  1. It seems that the bundle_adjust package is not available yet. I can't open the link (https://github.com/centreborelli/sat-bundleadjust).
  2. Can you show how to install the dsmr package. I can't find any information about it on the internet.

Looking forward to your reply, thanks!

Hello, thank you for your message :)

Here are some clarifications:

  1. Both packages bundle_adjust and dsmr concern optional bricks of the project. The only conda environment that is strictly necessary to install to test/train the model is satnerf. We used bundle_adjust to refine the RPC camera models of the training/test images, but you can simply download such data directly from the EarthVision 2022 release of the code. Of course, you can also use unrefined camera models, at the expense of some loss in accuracy.

  2. https://github.com/centreborelli/sat-bundleadjust should now be public. Check our related paper for an explanation of this bundle adjustment methodology for the RPC functions of satellite images.

  3. dsmr is not public yet, but you will simply get a warning message when you run the code, along with a rough approximation of the altitude MAE. We are working to remove the dsmr dependency of the code soon.

Let me know if you run into any further issues !
