Could you provide your CPU memory?

When I run `run_citygs_lod.sh` on the `residence` dataset, three `prune` programs run parallel, and each of them uses about 170G Memory of CPU, while I only have a 500G memory,...

After downsampling in matrix_city, the image resolution is 1600x900. Why is the resolution in sparse/cameras.txt showing as 1920 1080 with the PINHOLE values 2317.6449482429634 2317.6449482429634 960.0 540.0 (1920x1080 resolution)? How...

请问五相机拍摄的倾斜摄影模型原片，是否适合citygaussian?

2

我有一份5镜头无人机拍摄的倾斜摄影模型照片，用comap做前期处理，生成去畸变后的图像和camera.bin,points.bin以及images.bin，然后对影像进行2.0倍下采样，深度图也是2.0倍下采样，最后生成的3dgs模型不尽如人意，请问5镜头需要做前置什么特殊处理吗？
