C4 Camera Series Overview
Introduction
The C4 camera series is a revolutionary product family of intelligent high speed sensors. It is optimised for 3D profile measurement by means of laser triangulation technique. The 3D profile extraction is performed in the camera by using high performance Field Programmable Gate Array processors. At the same time the 3D profile data is sent to the PC over a Gigabit Ethernet interface (GigE). This extreme data reduction boosts the measuring speed to unprecedented levels without affecting the performance of the connected image processing unit.
Measuring Principle
The C4 camera acquires height profiles and height images based on the laser triangulation principle. According to this method a laser line is projected on the object from one direction. The C4 camera views the object from another angle defining the triangulation geometry. The resulting sensor image is evaluated by the C4 camera core and converted into a single height profile. By scanning the laser line over the object a complete height image can be acquired.
The figures below demonstrate some typical triangulation geometries. The following notation is used in the approximation of height resolution:
X= resolution along the laser line (lateral),
Y= resolution perpendicular to the laser line (longitudinal in the direction of motion),
Z= height resolution.
6 C4-2040-GigE Camera Hardware Reference Manual Rev. 2.1
Geometry 1
The laser line is projected perpendicular to the object surface, while the camera views the object under the triangulation angle α.
The height resolution can be approximated: Z X / sin(α)
Geometry 2
The camera views the object perpendicularly to its surface, while the laser line is projected under the triangulation angle α.
The height resolution can be approximated: Z ≈ ∆X / tan(α)

Geometry 3
The camera views the object under an angle α, while the laser line is projected under a different angle β.
The height resolution can be approximated: Z ≈ ∆X * cos(β) / sin(α + β),
in case α= β (direct reflex) : ∆Z ≈ ∆X / 2* sin(α)
Geometry 4
The camera views the object under an angle α, while the laser line is projected under a different angle β at the camera side.
The height resolution can be approximated: Z ≈ ∆X * cos(β) / sin(α),

The C4-2040-GigE Camera Algorithms
The C4-2040-GigE camera 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 ModeAndAlgorithmControlsCameraMode.
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 C4-2040-GigE 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.
C4-2040-GigE Camera Hardware Reference Manual Rev. 2.1 27
The Maximum Intensity Profile Mode (MAX)
In this mode the position of the maximum intensity of laser beam profile is calculated. The result includes the position value of the maximum (P
MAX
) as well as the maximum intensity value (I
MAX
).
AOI_TRSH

MA
X
I
MAX

R
The calculation of position value is performed with simple pixel accuracy, i.e. the evaluation of 1088 rows delivers a position range from 0 to 1087 pixels (11 bit). If there is more than one local maximum (e.g. when the intensity is saturated), the position of the first detected maximum is output. In order to avoid intensity saturation, it is recommended to activate the Multiple Slope Mode of the camera.
The detection of the maximum intensity position can be improved by enabling the smoothing mode of the FIR filter of the camera.
28 C4-2040-GigE Camera Hardware Reference Manual Rev. 2.1
The Threshold Mode (TRSH)
In this mode the position of left (PL) and right (PR) edge of the laser beam profile are detected for a given threshold value of intensity AOI_TRSH.
AOI_TRSH
P
TRSH
P
L
P
R
The position value of the laser line is approximated: P
TRSH
= (PL+PR) / 2. In order to simplify the digital representation the division over 2 is not performed and thus an integer representation with one subpixel is realised. The evaluation of 1088 rows delivers a position range from 0 to 2174 pixels (11 bit).
In threshold mode the camera can output either the left and right threshold position separately or the subpixel position (P
L+PR
) and the line width (PR-PL). Moreover, the maximum intensity value can be
optionally output.
The precision of the position calculation can be improved by enabling the smoothing mode of the FIR filter of the camera.

The Center Of Gravity Mode (COG)

The position value of laser line (center of gravity of beam profile) is then obtained from:

COG
= PL + Ms / Is .
In addition the laser line width can be delivered over the Data Channel DC1. The average intensity of the illumination profile can be calculated by normalising the sum of intensity value Is with the line width.
The precision of the COG calculation can be improved by enabling the smoothing mode of the FIR filter of the camera.

The FIR Peak Mode (FIR PEAK)
In this mode the first derivative of the intensity Gauss curve of laser beam profile is calculated.
The position of zero-crossing of first derivative is detected and output with subpixel accuracy (up to 6
subpixels). In this case the threshold AOI_TRSH is used to detect the first rising edge of the derived
intensity signal. Valid values of AOI_TRSH range from 513 to 1023 (Mono16).
More details regarding the operation of the FIR Peak mode can be found in a separate application
note.

the sensor image. It consists of a digital Finite Impulse Response filter (FIR) and can be operated in a
smoothing or differentiating mode.

The High Dynamic Range 3D Feature (HDR-3D) of C4-
2040-GigE
One of the most powerful features of C4-2040-GigE is the HDR-3D (High Dynamic Range)
functionality, which allows scanning materials and surfaces with inhomogeneous reflection properties.
Using HDR-3D the dynamic range of image intensity is extended up to 90dB, thus avoiding intensity
saturation.
The HDR-3D comprises two independent sensor functions:
Multiple Slope Function
The aim of the Multiple Slope function is to avoid the saturation of pixels during sensor chip exposure.
This high optical dynamic range is achieved by using a piecewise linear response. The intensity of
illuminated pixels, which reach a certain level, is clipped, while darker pixels remain untouched. The
clipping level can be adjusted 2 times within one exposure time to achieve a maximum of 3 slopes in
the response curve. The points of the curve, where the slope changes, are called “knee points”. The
latter are defined through the setting of clipping levels for the intensity (thresholds) and time points
within the exposure time. These parameters can be adjusted using the Genicam registers
ExposureSlopeDuration and ExposureSlopeThreshold of the AcquisitionControl (XML grid visibility must
be set to “Expert”). A knee point times is defined as percentage of the overall exposure time. A
clipping level is defined as percentage of the maximum sensor intensity (saturation).

Multi-Frame Readout Mode (NDR)
With the NDR mode it is possible to readout of up to 4 images at
different exposure times. It allows the combination of profile data
from different integration levels and it ensures accurate profile
data even for difficult surfaces with strong changes in reflectance.
The following timing diagram shows the function of NDR with 2
frames, when subsequent sensor images are acquired. The
exposure times for NDR frame 1 and 2 are depicted with It1 and
It2 respectively. Please note that the readout of the second frame R2 cannot begin unless the first
frame R1 has been readout. The same applies also between two subsequent sensor images, i.e. the
first NDR frame of sensor image 2 cannot be readout unless the last NDR frame of sensor image 1
has been readout.

The Data Output Format of C4-2040-GigE
The image and 3D data output is performed by selecting the data channel DC0-DC2 (node Camera ControlsDataOutput). Depending on the
algorithm the data can be acquired by enabling the corresponding output Data Channel (DC). Every DC is saved in a new image row. The bit depth of
output data depends on the selected algorithm. In 3D mode the camera outputs data with 16 bit. In Image mode the camera can output 8 or 16 bit
data. When in 8 bit Image mode, the DC0 delivers the 8 most significant bits of the 10 bit intensity data.

Advanced AOI Functions
The C4 camera features an area CMOS sensor, whose frame rate depends on the number of pixels to
readout. By defining a sensor Area of Interest (AOI) the frame rate and hence the profile speed will be
significantly increased due to the smaller number of pixels to readout.
In some cases the AOI position may not be constant and it should follow the image of laser line on the
camera sensor. The C4-2040-GigE features functions for performing an automatic AOI positioning
(AOI-Search) as well as line tracking (AOI-Tracking). A detailed description of these functions can be
found in a separate application note.

The Chunk Data Mode of C4-2040-GigE
General Description
The C4-2040-GigE features a Chunk Data mode for providing additional information to the acquired
image data. The implementation of XML nodes is performed according to SFNC 1.4:
Category ChunkDataControl
ChunkModeActive
ChunkModeSelector (OneChunkPerFrame, OneChunkPerProfile)
The ChunkData generated by the camera have the following format:
ChunkImage
1…N x ChunkAcqInfo
ChunkImageInfo
Depending on camera mode (image or 3D) the ChunkData block („ChunkAcqInfo“) can be sent as
follows:
in image mode, the camera can send only one ChunkAcqInfo block per image frame.
in 3D mode, the camera can send one ChunkAcqInfo block either per 3D frame
(“OneChunkPerFrame”) or per 3D profile (“OneChunkPerProfile”).
The „ChunkImageInfo“ is the last ChunkData sent by the camera and contains following data:
number of valid rows in ChunkImage
number of valid ChunkAcqInfo blocks
flags identifying the current frame as „Start“ or „Stop“
The ChunkAcqInfo block consists of totally 32 bytes containing following data
64 bit timestamp
32 bit frame counter
32 bit trigger coordinate
Trigger status
I/O Status
reserved
The data of timestamp, frame counter, trigger coordinate, trigger status and I/O status are assigned at
the start of every image integration.
When ChunkMode is disabled, the camera uses the “regular“ GEV image protocol, in which the
optional transfer of frames with variable height and payload is supported.
C4-2040-GigE Camera Hardware Reference Manual Rev. 2.1 49
Furthermore, when ChunkMode is enabled, the camera sends the full payload, even if the
ChunkImage or ChunkAqInfo blocks contain partially valid data. The number of valid ChunkImage
rows and ChunkAqInfo blocks can be read from ChunkImageInfo.
For example, when in Start/Stop mode with instant frame transmission, the camera stops the frame
acquisition as soon as the stop trigger occurs and transfers the complete contents of internal image
buffer. Using the ChunkImageInfo data block, it is possible to detect how many image rows and
ChunkAqInfo blocks are valid in the payload buffer.
The tag of ChunkData has big endian byte order. The data of ChunkData has little endian byte order.
An endian converter for ChunkData is not supported.
