Many floating Gauss points in the sky

[zwl995]

Hello, I used the configuration file you provided to train the rubble_c9_r4 scenario in the mill19 dataset, but the result I got was more clutter in the air. Can you help me see what caused it?

This dataset contains images in various lighting conditions. The model simply adds floaters to overfit such lighting differences.

Hi, @zwl995, during the development of our CityGaussian, the influence of light changes is ignored and thus can lead to undesirable floaters. To remove them, a favorable practice is introducing appearance embedding like VastGaussian.
