2 Technical data
2.1 Intended use
The 3DPIXA is a stereo camera using line scan technology. It provides stereo images as a
basis for the calculation of the 3D height data by one or multiple GPUs.
The 3DPIXA is designed for installation in machines and systems which are used for
commercial and industrial applications, such as:
Fast inline height measurement
Completeness check in 2D and 3D
Verification of 2D and 3D dimensions
Identifying micron defects
Combined 3D and 2D color inspection
3D web inspection
When using the 3DPIXA the following aspects must be recognized:
The owner of the machine or system in which the 3DPIXA is installed is responsible for
compliance with relevant safety regulations, standards and directives. Commissioning of
the 3DPIXA is not permitted until it has been verified that the machine or system in which
the 3DPIXA is installed complies with the safety regulations and standards of the country
in which the 3DPIXA is run.
The owner of the machine or system in which the 3DPIXA is installed must verify the
suitability of the 3DPIXA for its intended use.
The safety regulations of the country in which the device is used must be complied with.
The 3DPIXA may only be connected or used as described in this manual.
The 3DPIXA must be set up and installed in compliance with the instructions contained in
this manual.

3 Safety
3.1 Basic safety regulations
Read all supplied documentation carefully and ensure that you have fully understood its
contents before installing and operating the camera.
Follow the instructions in this manual, especially with regard to transport, storage,
installation, operation and maintenance.
Operate the camera only under faultless and safe conditions.
In the event of any fault or defect, stop the camera, the machine or the system in which
the camera is installed, and immediately inform the responsible person.
Modify or extend the camera only with the written consent of Chromasens GmbH. This
applies in particular to modifications and extensions which can negatively affect the safety
of the camera.
Comply with the ambient conditions described in this manual.
3.2 Safety instructions for maintenance and cleaning
Inform all personnel working on the system before carrying out service or maintenance
work.
Comply with deadlines and intervals for regular inspection work.
Before starting maintenance work, disconnect the 3DPIXA from the power supply.
Before starting maintenance work, let heat sources such as heaters, radiators or lighting
equipment and the camera cool down to room temperature.
Do not open or loosen screws or housing sections of the 3DPIXA.
Do not carry out repair works.
Transport the camera in its original packaging in order to prevent damage.
3.3 Residual risks
3.3.1 Hot surfaces
The body of the 3DPIXA will heat up during operation.
Do not touch hot surfaces without suitable protective gloves.
Allow hot surfaces to cool down before carrying out any work on the unit.
3.3.2 Electric voltage
The 3DPIXA runs with electric power.
Before carrying out any work on the 3DPIXA, disconnect all mains cables.
Make sure that the device is safely isolated from the power supply.
3.3.3 Electrostatic discharge
The 3DPIXA contains components and units which are sensitive to electrostatic charge.
Observe all precautionary measures for handling electrostatically sensitive equipment.
Make sure that the 3DPIXA, all tools and the person handling the equipment have the
same electrical potential.

3.4 Personnel requirements
The system owner must ensure that all persons working on the system are trained for the
required work and have read and understood this manual. This applies in particular to
personnel who only work occasionally with the 3DPIXA, for example during
commissioning and maintenance work.
Work on the electrical installations of the system may only be carried out by a qualified
electrician or by persons who have undergone electrotechnical training under the
supervision of a qualified electrician in compliance with applicable electrotechnical
regulations.
Only suitably trained and qualified persons are permitted to work with the 3DPIXA. Such
persons are qualified to work with the 3DPIXA device if they are familiar with its assembly,
installation and care as well as with all necessary precautionary measures.
The assignments and responsibilities of personnel charged with operation,
commissioning, maintenance and repair must be clearly defined. This definition must be
specified by the owner of the machine or system in which the 3DPIXA is installed.

4 Design and function
4.1 Components of a 3D scanner system
Fig. 3: Design of a line scan camera application
The following components are necessary for a typical line scan camera application:
Component
Function
1
Line scan camera
Scans the image line by line and communicates with the frame
grabber.
2
Illumination
Lights up the information carrier/scan area on the passing object.
The Chromasens Corona II illumination system is an ideal
supplementary option for the 3DPIXA camera.
3
Illumination
controller
Controls and monitors the illumination unit. The Chromasens
Corona II illumination has integrated temperature/voltage sensors
which can be read out with the XLC4 controller. By using the XLC4
controller, the illumination unit can be monitored and kept stable.
4
Frame grabber
(PC plug-in card)
The image data are sent to a PC by means of a frame grabber with
a CameraLink interface. The frame grabber establishes the
necessary hardware connection to the PC.
5
PC with GPU and
dongle
The PC serves for subsequent processing of the image data and
can optionally control the illumination system.
6
Conveying unit
Moves the scanned object past the 3DPIXA camera.
7
Speed detection
The speed of the object / conveyor belt can be detected by means
of an optional incremental encoder. The encoder can be connected
either to the 3DPIXA camera or to the frame grabber.
8
Power supply
Both, the 3DPIXA camera and the illumination system, require a
suitable power supply.
