Noise in the image point cloud with background sky #506

Open Livan89 opened 4 years ago

Good afternoon.

Sorry for my english

When building models in which there are background images with sky, usually when it is cloudy, the densification process always generates a lot of noise in the dense cloud, does anyone have any idea of any solution? TractorNubeDensa g0033081

There are few things that you can try:

increase --number-views-fuse as a param to DensifyPointCloud
increase Descriptor Min Magnitude Threshold = 0.01 by writing it in a TXT file (ex options.txt) and call DensifyPointCloud with --dense-config-file options.txt
take more photos and when the light is evenly distributed, ex a cloudy day
