5.2 Setting up in the system

Vocabulary :

= size of the sensor line (40,96mm for the 4k 10µm)

FOV

= Field Of View (width of the web inspected by the sensor line) in mm.

= Working distance (from the Lens to the Web) in mm.

= focal distance of the lens in mm.

= Speed of the web in mm/s

We have :

w/FOV = f/L

The ratio M = w/FOV is called Magnification. The FOV is grabbed by 4096 or 2048 pixels in the width. In order to get a ratio of 1 :1 in your image, at the web speed of S, your line rate has to be set : Line Rate = (S/FOV) x 4096 (or 2048)

: if the FOV = 11 cm (110mm) and the speed of the web is S= 0,3 m/s (300mm/s) the line rate will be :

Line Rate = (300 /110) x 4096 = 11170 Lines/s.

If you use a 60mm lens, the working distance will be : L = (60 x 110) / 40,96 = 161mm. This will certainly require a macro lens.

6 CAMERA SOFTWARE INTERFACE

6.1

GigE Vision concepts

Camera interface is compliant with "Gigabit Ethernet Vision" (GigE Vision) or (GEV). GEV normalizes image transport and camera control communications over usual IP networks. Physical GEV carrier has a bandwidth of one gigabit per second (1Gbit/s). GEV is widely used by camera manufacturers and imaging software suppliers.

6.1.1 GenICam

Camera interface is compliant with "Generic Interface for Cameras" (GenICam). GenICam normalizes the camera control interface with software application. The target is to have a single application controlling cameras from any model and brand the same way. It introduces the concept of user manual, not for humans but to software application. Application reads this user manual to control cameras. GenICam has 2 parts, "GenICam Standard" and "GenICam Standard Features Naming Convention" (SFNC)

6.1.2 GenICam Standard

6.2 Getting started with GigE Vision interface

This chapter shows how to connect a GEV camera for the first time.

6.2.1 Network setup

The following is the simplest example of a Gigabit IP network.

A single Ethernet cable is connected in RJ45 receptacles of GEV camera and PC. Select a "CAT6"

shielded twisted pair quality to get a reliable 1Gbit/s. This cable is available at any computer shop.

Recent PC have a gigabit RJG45 plug on the motherboard. Factory setup has set the camera to the default IP subnet 169.254.X.X. The PC interface is set to this default IP subnet as follows: Open the Network interface properties. Settings are shown on Windows XP.

Set TCP-IP v4 interface properties to IP address 169.254.0.101 and subnet mask to 255.255.0.0

6.2.2 Software installation

A GigE Vision software is required. Use your own or install PureGEV, downloadable from

www.e2v.com/cameras

site. A PureGEV license is included in camera package. Refer to PureGEV installation manual for instructions. The following assumes Pleora's PureGEV is installed. To keep things simple, the firewall should be temporary turned off.

e2v semiconductors SAS 2011

Click on camera and check "License" value is "Valid" and click OK. In GEV Player window, "Gev Device control" and "Play" are now active.

Once connected to the Camera you have an easy access to all its features when you click on “GEV DeviceControl”. The visibility of these features can be associated to three types of users: Beginner, Expert or Guru. Then you can make life easy for simple users.

Beginner :The number of features with “Beginner ” visibility should be limited to all basics features of the device, and easy to use. Expert : features that require a more in-depth knowledge of the camera functionality. This is the preferred visibility level for all advance features in the camera. Guru : Advanced feature that might bring the camera into a state where it will not work properly anymore if it is set incorrectly for the current mode operation.

Click "Play" to start grab. Check camera image on display.

DeviceTemperature :

Return by the camera : Temperature in Q10.2 format (8 bits signed + 2 bits below comma). Value is between -512 to 511 in °C.

The temperature Sensor is placed on the CCD driver Board, close to the Sensor itself. The Temperature displayed is one of the highest possible in the Camera. Then it can be monitored to activate the standby mode, in case of too high temperature (see insert below) The limits are always referenced by the internal temperature sensor. (cf APPENDIX B : Thermal Management)

 A standby mode, what for ?

The Standby mode stops all activity on the sensor level. The power dissipation drops down to less than 5W. During the standby mode, the Camera carry on sending black images through the CameraLink outputs in order to avoid any disruption in the application system.

Once the Standby mode turned off, the Camera recovers in less than 1ms to send images again from the sensor. But it’s necessary to grab an image of about 100 lines because these first lines after the Sensor Power down don’t have a correct level (due to the reestablishment of the black reference level.

6.3.7 AcquisitionControl

The Acquisition Control section describes all features related to image acquisition, including the trigger and exposure control. It describes the basic model for acquisition and the typical behavior of the device.

An Acquisition is defined as the capture of a sequence of one or many Frame(s)

A Frame is defined as the capture of Width pixels x Height lines. A Line starts with an optional Exposure period and ends with the completion of the sensor read out..

The AcquisitionMode controls the mode of acquisition for the device. This mainly affects the number of frames captured in the Acquisition (SingleFrame, MultiFrame, Continuous).

The AcquisitionStart command is used to start the Acquisition.

The AcquisitionStop command will stop the Acquisition at the end of the current Frame. It can be used in any acquisition mode and if the camera is waiting for a trigger, the pending Frame will be cancelled.

The AcquisitionAbort command can be used to abort an Acquisition at any time. This will end the capture immediately without completing the current Frame.

AcquisitionFrameCount controls the number of frames that will be captured when AcquisitionMode is MultiFrame.

AcquisitionLinePeriod controls the period of each Line. The AcquisitionLineRate is calculated from

this value.

AcquisitionStatusSelector and AcquisitionStatus can be used to read the status of the internal acquisition signals. The standard acquisition signals Status are: AcquisitionTriggerWait, AcquisitionActive, FrameTriggerWait, FrameActive,

6.3.9 CounterAndTimerControl

This section lists all features that relates to control and monitoring of Counters and Timers. A Counter is used to count internal events (FrameStart, FrameTrigger, …), I/O external events (Input Line rising edge, …) and even clock ticks. It can be Reset or Read at anytime. Counters and Timers can also be cascaded to increase their range if necessary.

Timers are readable and can be used to measure the duration of internal or external signals. A Timer can also be used to generate a timed strobe pulse with an optional delay before activation. In AVIIVA EM1 camera, 2 x Counters and 2 x Timers are available and are used in different applications: ¾ A Counter is used to count internal events.

Ex: number of frame trigger, number of line started…

¾ A timer is used to measure the duration from

an event. Ex: starts the Frame Acquisition 200µs after the reception of a Frame Trigger.

• Counter :

To start counter there are several possibilities: ¾ There is no condition to start the counter (CounterTriggerSource = Off), the counter increment

each time the event occurs.

¾ There is a condition on the start of the counter: this condition has to be selected in the enumeration

of the CounterTriggerSource feature and the activation with CounterTriggerActivation feature.

The counter stops incrementing if : ¾ The CounterDuration feature is equal to the CounterValue, even if a new event selected occur no new

increment of the counter and no reset happened.

¾ A Reset happened either due to the CounterReset command (Enable with

CounterResetSource=Software) or due to an external event happened on Inputs (Enable with CounterTriggerSource and CounterTriggerActivation features). If a new event happens the counter

starts from 0 to count if condition of start is true.

 Ultimate Concept: A different way to set the Gain in order to improve the Tap balance

The “U” Concept has been developed to get a real improvement in term of tuning for the multi-Tap sensors : As each sensor tap is driven by a different analog Chain, for an increasing of the global gain of the Camera, each tap can have a different behavior on its own Gain and offset. This means that to be perfectly adjusted, a balance of the taps should be performed ideally after each change of the Gain. The Ultimate Concept offers a solution as following:

The Global analog Gain of the Camera is divided in 2 parts :

¾ A preamp-Gain which is composed of several steps (5 x steps of 6dB, from -24dB to 0dB on the AVIIVA

EMx series)

¾ An amplification Gain with a continuous tuning (from 0dB to +8dB on the AVIIVA EMx series)

At each step of Preamp Gain, a Tap balance has been performed in factory for both Gains and Offsets and saved in ROM memory. When a new value of Preamp Gain is set, the factory settings of the both Gain and offset balance is automatically reloaded. For sure, the user can also perform his own balance (automatically or manually) and can save it in one of the four dedicated memory banks.

After the Preamp Gain level, the user can add more gain by using the Amplification Gain:

¾ The best tuning is when the Amplification Gain is set at its minimum possible ¾ Each change of Preamp Gain value loads automatically the associated values of the Tap balance (Gain and

offset for each sensor tap).

This action takes more time than simply changing the Amplification Gain

6.3.10.3 Tap Balance

 How to perform a Tap Balance ?

Why and when performing a Tap Balance ?

Each output of the sensor (Tap) has its own analog Chain and behavior. There could have some discrepancies between these outputs in extreme conditions of Gain or temperature The Tap balance is already performed in factory for each level of Preamp-Gain. If necessary, the Tap balance can be performed again by the User on both Offsets and Gains

The Procedure is the following :

Tap Balance by Offsets

¾ Cover the Lens of the camera to get a dark uniform target. This is not recommended to perform an

Offset balance under light conditions.

¾ Launch the Tap Offset Balance ¾ The process takes a few seconds and can be interrupted when you want

Tap Balance by Gains

¾ Provide an uniform light target to the camera : This is recommended to have a global level of around at

least 70% of the saturation, otherwise, with a low light level (< 30% of the Saturation) the Gain has less effect than the Offset and your balancing won’t be efficient.

¾ Launch the Tap Gain Balance ¾ The process takes a few seconds and can be interrupted when you want

¾ You can save the result in memory (result for both Gains and offsets).

Internal Process

During the calibration process, the Camera calculates averages on some strategic ROIs (around the junction between taps) and then estimates the slope of the tangents and then the projections on each side of the junction.

The adjustment between these two neighbor taps is calculated to cancel the difference between the two projections (right and left).

All these features are out of the SFNC standard. The functions are exactly the same as the EMx series in Cameralink interface.

Some Warnings can be issued from the PRNU/FPN Calibration Process as “pixel Overflow” or “Pixel Underflow” because some pixels have been detected as too high or too low in the source image to be corrected efficiently. The Calculation result will be proposed anyway as it’s just a warning message. The Status Register is changed and displayed in “Status” section (detailed chap §6.4.5)

 How is performed the Flat Field Correction ?

What is the Flat Field correction (FFC) ?

The Flat Field Correction is a digital correction on each pixel which allows :

¾ To correct the Pixel PRNU (Pixel Response Non Uniformity) and DSNU (Dark Signal Non Uniformity) ¾ To Correct the shading due to the lens ¾ To correct the Light source non uniformity

Before After

How is calculated / Applied the FFC ?

The FFC is a digital correction on the pixel level for both Gain and Offset. ¾ Each Pixel is corrected with :

o An Offset on 8 bits (Signed Int 5.3). They cover a dynamic of ±16LSB in 12bits with a resolution of

1/8 LSB 12bits.

o A Gain on 14 bits (Unsigned Int 14) with a max gain value of x3 o The calculation of the new pixel value is : P’ = ( P + Off).(1 + Gain/8192)

The FFC processing can be completed with an automatic adjustment to a global target. This function is designed as “FFC Adjust”. This adjustment to a User target is done by an internal hidden gain which is recalculated each time the FFC is processed while the FFC adjust function is enabled.

The FFC is always processed with the max pixel value of the line as reference. If enabled, the FFC adjust module (located at the output of the FFC module) calculates the adjustment gain to reach the target defined by the User.

When the FFC result is saved in memory, the adjust gain and target are saved in the same time in order to associate this gain value with the FFC result.

How to perform the Flat Field Correction ?

FPN/DSNU Calibration

¾ Cover the lens ¾ Launch the FPN Calibration : Grab and calculation is performed in few seconds

PRNU Calibration

The User must propose a white/gray uniform target to the Camera (not a fixed paper). The Gain/Light conditions must give a non saturated image in any Line. The Camera must be set in the final conditions of Light/ Gain and in the final position in the System. I f required, set a user target for the FFC adjust and enable it.

¾ White uniform (moving) target ¾ Launch the FFC ¾ Enable the FFC ¾ You can save the FFC result (both FPN+PRNU in the same time) in one of the 4 x FFC User Banks. ¾ The user target and Gain are saved with the associated FFC in the same memory.

Advices

The AVIIVA EM1 Cameras have 4 x FFC Banks to save 4 x different FFC calibrations. You can use this feature if your system needs some different conditions of lightning and/or Gain because of the inspection of different objects : You can perform one FFC per condition of Gain/setting of the Camera ( 4 Max) and recall one of the four global settings (Camera Configuration + FFC + Line Balance) when required.

 FFC Adjust : A good usage.

When there are several Cameras to set up in a system on a single line, the most difficult is to have a uniform lightning whole along the line. If each Camera performs its own Flat field correction, relative to the max of each pixel line, the result will be a succession of Camera lines at different levels. => The FFC Adjust function allows to set the same target value for all the Cameras in the system and then to get a perfect uniform line whole along the system with a precision of 1 LSB to the Target.

The reasonable value for the User Target is not more than around 20% of the max value of the line.

6.3.12 LUTControl

The User can define or upload a LUT in the Camera that can be used at the end of the processing. The LUT is defined as a correspondence between each of the 4096 gray levels (in 12 bits) with another outputted value. For example, a “negative” or “reverse” LUT is the following equivalence : Real value Output value 0 4095 1 4094 2 4093

Then the size of each value is 12bits but the exchanges with the Application/PC are done on 16 bits : For 4096 gray levels (from 0 to 4095) the total file size for a LUT is 8Ko.

If the LUT is enabled, The Contrast Expansion (both Digital Gain & Offset) will be

automatically disabled..

6.3.13 Statistics and Line Profile

This function allows the User to get some statistics on a pre-defined ROI. On request, the Camera acquires and then calculates some key values as the min, the max, the average or the standard deviation in this Region of Interest.

The grab and calculation command and also the collection of the results is not performed in real time as it is done through the register access.

The Calculated values are detailed as following : o Pixel average Value (

PixelROIMean

) : Average

gray level value calculated on whole Region of interest : Unsigned format value : U12.4

o Pixel Standard deviation

(

PixelROIStandardDeviation

) : standard deviation

of all the pixel gray level values of Region of interest : Unsigned format value : U12.4

o Pixel Min value (

PixelROIMin

) : Minimum gray level pixel value on the whole region of interest.:

Unsigned format value : U12.4

o Pixel Max Value (

PixelROIMax

) : Maximum gray level pixel value on the whole region of interest:

Unsigned format value : U12.4

Packet_Resend mechanism

The AVIIVA EM1 camera embeds a dedicated memory to store the data frames in order to be able to resend packets when requested by the host driver. If the host driver detects that one or multiple packets are missing then resend request commands are sent to the camera. This feature can be enabled or disabled depending on the GEV driver used. But this feature is always enabled in the AVIIVA EM1 camera. In the AVIIVA EM1 camera the sensor stream has a higher priority than the packet_resend channel. This means that when the line frequency increases the time available for packet resend decreases. The AVIIVA EM1 camera has a 512Mbit memory let say 8192 packets of 8192 bytes. If the host driver requests a single packet it sends a request command with the block_ID and the packet_ID. If it requests multiple following packets it sends a request command with the block_ID, the packet_ID of the first missing packet and the packet_ID of the last missing packet. The camera resend the packets provided there are still in its memory. If not the camera answers the requests with an extended status code (if enabled) indicating why the packets can’t be resend.

8 APPENDIX B : Thermal Management

8.1 Heat Sinks

The most important source of heat in the camera is around the sensor. The EM1 Camera dissipates around 11W max with 4 taps at 31.25MHz (4K pixels version) The Camera has been designed to dissipates the maximum of the internal heat through its front face : The packaging of the sensor is larger to increase the surface in contact with the front face and then improves the dissipation. In the system, the camera has to be fixed by its front face with the largest contact possible with a metallic part. Without any specific cooling system, a simple air flow around the camera will improve roughly the dissipation.

The EMx Camera series are already delivered with 2 Heat Sinks, but if necessary, additional heat sinks are available (set of 2) and they can be fixed on any side of the front face :

Set of 2 x Heat Sinks : Part number AT71KFPAVIVA-CAA

One heat sink can decrease the temperature of the front face of about 5°C down.

8.2 Temperature dropping

Some measurements have been done to establish the dropping temperature steps between different control points :

¾ Ambient room temperature (burning room with controlled pulsed air) ¾ Front Face of the Camera ¾ Internal Temperature sensor (measure available with DemoGev).

Temperature Dropping

0 102030405060

Front face Mainboard

It has been established that the steps are the following (after a certain time) :

¾ Ambient room to Front Face about : + 10°C ¾ Front Face to internal sensor about : + 15°C

Then an average of + 25°C between the room ambient temperature and the internal sensor. The specification limits have been fixed at :

¾ 45°C for the ambient temperature ¾ 55°C for the Front Face ¾ 70°C internal Sensor.

The ambient temperature is necessary defined here as a pulsed air or with an air flow around the camera otherwise the temperature around the Camera is not homogeneous and can be much more important than the one measured in the room.

8.3 Performance curves versus Temperature

¾ These curves have been established with a 4k Pixel Camera (worst case). ¾ The “Camera Temperature” is given by the internal Sensor of the Camera. ¾ All the values in LSB are in 12 bits

Darkness Noise vs Temperature : For both Min an Max preamp Gain values

Darkness Noise vs Temperature : Detailed curve for the Min preamp Gain value

The Cameras tuning is done in factory after a certain time of warm up (close to a “normal condition of use) in order to ensure that the Camera will give its best while runing 24h a day. This explains a slight decreasing of the noise when the temperature rises up.
