The C2 Sensor Algorithms

The C2 series can be operated both in a variety of 3D profile modes and in image mode. The current
operation mode can be chosen by setting the parameter:
Camera Controls→ ModeAndAlgorithmControls→CameraMode.
The frame rate can be increased in all camera modes by reducing the AOI size. In the image mode
the frame rate is limited by the output rate of the camera interface (GigE). However, due to reduced
data size in profile mode the frame rate is limited only by the sensor output rate. As a matter of
principle the processing speed is independent of the chosen profile mode and is determined by the
AOI size.
In all profile modes only intensity values higher than the AOI intensity threshold AOI_TRSH are
processed in order to suppress weak signal noise. In case that no position value can be found, e.g.
no intensity value is higher than threshold, the position value 0 is returned.

The Image Mode (IMG)

In the image mode the C2 camera is operated similar to a standard CMOS camera. In this mode grey
scale data of 8 or 10 bit resolution are acquired over the camera interface. Furthermore, the sensor
can be divided into multiple regions, whose data can be summarised in one output frame.
