EO-NeRF data #2

Open jieeeeeeeeeee opened 6 months ago

jieeeeeeeeeee commented 6 months ago

EO-NeRF is an exciting project. The EO-NeRF paper mentions, 'The input data and EO-NeRF results are released to contribute to the creation of a NeRF benchmark for multi-date satellite images.' Could you confirm if the data used in EO-NeRF will be open-sourced? Currently, the [Data] link on the EO-NeRF project website is inaccessible.

Hello @jieeeeeeeeeee , thank you for the reminder :) The [Data] link is now updated and you can access the IARPA areas of interest discussed in EO-NeRF. The rest of areas are the same as in SatNeRF.

Hello @rogermm14, thank you for your response! The data from the EO-NeRF project is available for download. I appreciate your assistance in resolving this matter :)

Another question, IARPA Data includes 49 WorldView-3 images. In our project, we have found that the 3D reconstruction results using all these images are not ideal. Our speculation suggests two possible reasons:

  1. Some images among the 49 have suboptimal quality, such as excessively skewed perspectives or dim radiometric conditions, leading to a decrease in pose accuracy during global Bundle Adjustment (BA).
  2. Additional preprocessing may be necessary, similar to the approach used in the DFC2019 dataset, involving atmospheric correction or Radiometric Normalization to correct radiometric information.

Do you have any suggestions, for example, on how to filter the images? any advice you could give would be much appreciated. :raised_hands:
