In the figure below, the significance of the world coordinate system is outlined as an example. The
provided 3D coordinates are always provided in the calibrated world coordinate system. This makes
it possible that the processing of the coordinate positions can take place regardless of the installation
position and angle of the device.

The image above shows two different mounting positions of the device on a mobile machine. In both
cases, the world coordinate system is defined identically (1). For both mounting positions, the internal
measured value of the device differs by the mounting position (2).
By correctly calibrating the device to the world coordinate system, the same X value is provided for the
object and both mounting positions (within the world coordinate system).
