2D image number for segment
FinnJob opened this issue · 4 comments
Thank you for your excellent work!
I wonder how many 2D images are required at minimum for segmenting a 3D point cloud? Thanks!
Thank you for your interest in our work!
In ScanNet dataset, we directly use one image every 20 frames in one scene. The number of 2D images for every single scene depends on the total number of frames. We didn't try the relationship between the number of 2D images and segmentation quality.
Thank you for your reply!
And one more thing. Is it necessary for each frame of the image to be roughly continuous? Would it be feasible to use discretely captured images from different camera positions?
The images should be as continuous as possible, as we use a bottom-up block merging method. We first merge adjacent images. You may also try to disrupt the order of the images to compare the results.
Ok, thanks!
