Perfect! That's the diagram I was after. Thanks!

Your Y and Z are swapped. From Main.h....

The 3D coordinate system is defined as positive X going to the right, 
positive Y going up into the air, and negative Z going into the scene (camera look direction).
This is also the standard OpenGL coordinate system.
The origin is the center of the turn table.

FreeLSS Setup Parameters

null@example.com (C_D) — Fri, 01 Jan 2016 10:01:22 +0000

Can someone give point me to where the physical setup parameters are described for FreeLSS?

I have a Ciclop scanner (or PiClop), so slightly different geometry to an Atlas3D. I think I have some incorrect values entered in my setup and I may have misinterpreted the meaning of some of the short descriptions on the setup page. The comments all refer to X Y Z locations of cameras and lasers, but I'm not entirely sure where the X0, Y0, Z0 origin is that everything is measured from. I have assumed the center of the rotating platform, is that correct?

Currently when i start a scan the scanner goes through the process but I get the following debug output. The bit about 'object bounds failures' sounds sort of like my setup parameters are so far out it cant create any sensible data from the scan.

My setup parameters are currently as follows. Do these look logical?

Camera X 0 mm.
X-compoment of camera location. ie: The camera is always at X = 0.

Camera Y 310mm.
Y-component of camera location. ie: The distance from camera center to the XZ plane

Camera Z 100.4mm.
Z-component of camera location. ie: The distance from camera center to origin

Right Laser X 175mm.
X coordinate of the right laser. This is how far the laser is from the camera.

Right Laser Y 310mm.
Y coordinate of the right laser

Right Laser Z 100.4mm.
Z coordinate of the right laser. The laser is parallel with the camera focal point

Left Laser X -175mm.
X coordinate of the right laser. This is how far the laser is from the camera.

Left Laser Y 310 mm.
Y coordinate of the right laser

Left Laser Z 100.4 mm.
Z coordinate of the right laser. The laser is parallel with the camera focal point
