What are the green dots?

Thanks for your response about these unwanted green points.

Is it possible to filtering them (and other unwanted green points) by a lasso tool ? Like in photoscan.

For filtering tool, i have only found the selection by cube (recontruction region box). I hope this is not the only selection tool, because it’s not easy to manipulate. Is there an other selection method for filtering unwanted points (not for tie-points bur for dense point cloud)?

Thanks in advance for help !

Regards.
