Figure 23. Different layouts. (Left) Ring with 3 sensors. (Right) Side-by-side.
Calibration target object
In a ring and opposite layout, a prism is used. A prism is essentially a polygon in the XZ-plane,
extruded along the Y direction. Its dimensions must be known: the X and Z coordinates of all
vertices of the polygon in the XZ-plane are required to accurately define the prism. (These should
be provided by the manufacturer.)
In a side-by-side layout, a flat, smooth, and rigid object that spans the entire width of the
combined measurement area, in the XZ-plane can be used. In this case, its precise dimensions are
irrelevant.
Creating a UMS
Z-Expert provides a wizard to help create the UMS for common sensor layout, such as ring, or side
by side, or to define custom layouts. Once the UMS is created, a multi-sensor system node will
appear in the Sources Explorer of Z-Expert. Please refer to the Z-Expert help for a detailed
procedure.
