Doubts about the use of segmented images for reconstruction

[DYH200009]

Hello, dear author, thank you for your excellent work.
Recently, when I used the segmented data set for 3D reconstruction, the following puzzling situation occurred. When my background was colorless, there were a lot of strange splash points.

After reading your readme.md carefully, this is the problem caused by density, but when I switch to sdf for reconstruction, the effect is like this.

Do you have any good ways to solve this kind of problem? what parameters do you need me to adjust?
