StructureBuilder Trajectory issues during merging

In larger scenes, I need to record motion trajectories. RoomCaptureSession always starts from (0,0,0), and I use the last tracked point as the offset value to connect multiple trajectory points, just like StructureBuilder merging models

But when StructureBuilder merged, it eliminated some of the models, which would make the trajectory points I saved lose accuracy, and I cannot know how much scene size was specifically eliminated between them

Is there any way you can help me?
