Sfm algo

Just updated odm to engine 2.8.4 and a couple parameters caught my eye.

matcher-neighbors defaults to 0? if left at zero matching is based on triangulation. what is the benefit of this and what is recommended?

sfm algo has a new setting planar. the info button pretty much spells it out so no question about that and triangulation, however incremental is not described and am curious what the difference between incremental and the other two.

Thanks, you all are awesome!

Triangulation takes advantage of any pitch/roll/yaw data available for the camera orientation, though it’s somewhat touch-and-go in use, as every maker has a different specification for how to store this and some makers have multiple specifications. We haven’t quite caught up in parsing all the use cases.

Incremental is described here.
