[Background]: We are building an app which allows users to continously update/extend the map of a large space.
[Finding]: Say, I already scanned a corner. Then the layout is changed a lot which made it hard for Placenote to recognize, but it still successfully localized. However, from the visualized point-cloud we can see obviously that the point-cloud of the old layout is there. Even if I extend the map by ‘StartSession(true)’, new feature points according to the new layout can be generated, but the old one cannot get eliminated!! This will cause a problem that the map size (number of feature point) will grew bigger and bigger in a long period of time.
1). I would like to confirm, is my findings correct or not?
2). If yes, is it possible to eliminate old point-cloud with the current SDK?
3). If not, is that something to be considered to have in future version?
