Figure 6. The various terms used in this document (defined below) are depicted here, seen in the XZ-plane. The Y-axis is
perpendicular to the page. Note that the diagram is not to scale.
X-Axis
The X-axis is the lateral axis that runs along the laser line emitted by the 3D sensor.
Z-Axis
The Z-axis is the vertical axis where height measurements are made. Height measurements can be made on only
a portion of the Z-axis, called the Z range. The Z-axis is always perpendicular to the X-axis.
Y-Axis
The Y-axis is the axis of the scan or travel direction. It is perpendicular to both X and Z axes, i.e., perpendicular to
the XZ-plane.
