Transformations
The transformation settings determine how data is converted from sensor coordinates to system coordinates (for an overview on coordinate systems, see Coordinate Systems).
|
If you perform an alignment using the Surface Align Wide or Surface Align Ring tools, these values are not updated. For more information, see Aligning Sensors to 6 Degrees of Freedom. |
Parameter | Description |
---|---|
X Offset |
Specifies the shift along the X axis. |
Y Offset |
Specifies the shift along the Y axis. |
Z Offset |
Specifies the shift along the Z axis. A positive value shifts the data toward the sensor. |
Angle X | Specifies the tilt around the X axis. |
Angle Y | Specifies the tilt around the Y axis. |
Angle Z | Specifies the tilt around the Z axis. |
When applying the transformations, the data is first rotated around X (clockwise, with the X axis toward the viewer), then Y (counterclockwise), and then Z (clockwise), and then the offsets are applied.
|
Setting Angle X or Angle Z, and to a lesser extent Y Offset, to a non-zero value increases CPU usage when scanning, which reduces the maximum scan speed. |
|
Artifacts may appear in scan data when Angle Z or Angle X is set to a non-zero value if encoder trigger spacing is set too high (resulting in a low sampling rate). |

The button is labeled Top, Bottom, Top-Left, or Top-Right, depending on the system. Transformations can be configured separately for each sensor. |
