I am woking on a project where i want to measure the distance between 2 points in the room (through X,Y,Z coordinates).

There is a fixed startpoint, this point will always be the same (can be seen as origin, X=0, Y=0, Z=0).

It needs to have an accuracy of about +/- 10 cm.

It will be indoors so i don't know if GPS will be accurate enough ?

Thanks in advance,

Can the points be anywhere in the room (x,y,x)? How big is the volume in which you want to measure?

What are the points? Are they visible objects?

Camera tracking is an option, if you can see the points.

Some form of sonar could work.

There are some cheap(ish) LIDAR sensors (Search Sparkfun)

Servo tracking opto detectors and triangulation could work.

How fast should the measurement be? Are the points moving?

The more info you can give the better the chance of getting an answer that will fit.
