Example
The following figure illustrates how to apply the world coordinate system to an application .
Z
X
The reference point, the origin of the world coordinate system, is set in the front axle of the vehicle (grey
cross) . The distance of the device to the reference point on the X axis is entered in the field "X position of
sensor" . The distance of the device to the reference point on the Y axis is entered in the field "Y position
of sensor" . The distance of the device to the reference point on the Z axis is entered in the field "Z
position of sensor" .
Finally, the 3D data is calculated taking into account the entered position of the device .
The signs for the X/Y/Z axes depend on the corresponding coordinate direction in the world
coordinate system . In the figure above, the device on the X axis has a negative sign (against
driving direction) and on the Z axis a positive sign .
