Coordinate Systems

Data points are reported in one of three coordinate systems, which generally depends on the alignment state of the sensor.

• Sensor coordinates: Used on unaligned sensors.
• System coordinates: Used on aligned sensors. Applies to either standalone or multi-sensor systems.
• Part and section coordinates: Data can optionally be reported using a coordinate system relative to the part itself.

Understanding coordinate systems is an important part of understanding measurement results. These coordinate systems are described below.

For all Gocator sensors, Y increases moving from the camera to the laser; for more information, see the coordinate system orientations illustrated in the specification drawings of your sensor in Sensors.
