Object scale in Hololens not matching real world scale, again
Hi,
I've already posted an issue here concerning the object scale not matching the real world scale. That particular issue was closed due to there actually being a discrepancy between the model and the real world object.
However, further tests with bigger objects revealed that even after measuring, the scale still doesn't match, it just is less noticeable with smaller objects. I measured a table for testing and found the same thing. Even after calibrating my display, it seemed to be short a few centimeters.
I've found some posts here and here which pretty much exhibits the same issue I'm having.
Is there anything I can do about this? How do I adjust for that issue/circumvent it?

If you know how much the offset is for the object then scale to adjust for it in your app. One of the other post's said that he noticed that it was always off by 1.5% so add 1.5% scale to your object.
Overlaying 3D models such as a table onto another table is not going to be a particular strong suite of any AR device because any discrepancies are going to be noticed immediately. I would try to stay clear of overlaying in that way. The bigger the object the more noticeable any discrepancies will be.

This happens for me too, the hologram is placed correctly, and the hologram scale is not changed in any of the script in the program (I've also used a floating text with the object scale to be shure about that).
The real world object is about 7 cm smaller than the 3d model in the hololens I use, in another hololens is 7 cm longer, it seems like a sensor issue, also because from the rs4 the sensor tuning utility is not anymore available in favor of automatic sensor tuning, in fact it happened that one time the hologram fitted the real object perfectly, and after about 20 mins, without changing anything, the hologram was of different size
