Start-up Start-up A Gigabit Ethernet port (1000Base-T) on the host computer is necessary. 1. Connect the camera with the appropriate data cable to the computer. 2. Plug the 15-pin connector of the power supply to the camera. 3. Switch on the power supply. Camera control commands To configure the internal image processing, a serial command interface is provided.
Start-up Each command consists of a command letter, followed by an equals sign and a parameter value in hexadecimal number representation. The command letter is case sensitive. Hexadecimal values are always upper case and consist of 1 to 4 digits. The command is activated by a carriage return ([CR], ASCII character number 0x0D). Serial communication operates in echo mode by default. This means that each character received by the module is echoed back to the sender.
Start-up If the intended action does not need any parameter, it is sufficient in most cases to send the command letter only, directly followed by [CR]. At the beginning of a command sequence it is good practice to check the serial communication by sending just a [CR] to the camera and verify that the command prompt > is returned. There is an input buffer holding a few characters but no hardware handshake.
Camera interfaces Camera interfaces This chapter gives you information on the control junction, inputs and outputs and trigger features. www For accessories like cables see: http://www.alliedvisiontec.com/emea/products/ accessories/gige-accessories.html Control connector Camera I/O connector pin assignment (15-pin D-sub connector) This connector is intended for the power supply as well as for controlling the camera via its serial RS232 interface over a COM port.
Camera interfaces Pin Signal Direction Level Description 14 Sensor tempera- Out ture too high Active low 15 Frame-sync output Active low Out Table 7: Camera I/O connector pin assignment Power supply (pin 1-4) The camera requires 12 V +5% DC and maximum 1.5 A. The voltage should not fall below 12.0 V and should not exceed 12.6 V. It is recommended to use respectively both pins (1+2, 3+4) for power supply.
Camera interfaces Figure 4: Trigger input diagram The current (1) which flows through the optocoupler and the integrated dropping resistor should be > 5 mA and should not exceed 20 mA. Pearleye P-007 LWIR For continuous periodical trigger the pulse must be at least 100 μs in length and the periodic time must be exactly 24.96 ms ± 10 μs. Pearleye P-030 LWIR For continuous periodical trigger the pulse must be at least 82 μs in length and the periodic time must be exactly 41.608 ms ± 20 μs.
Camera interfaces An indication of sensor temperature being too low results in a degradation of image quality and inexact temperature measurement. If this control output does not become inactive after some minutes of operation, the ambient air temperature of the camera might be too low. To resolve this, heat up the camera temperature above approx. 15 °C (Pearleye P-030 LWIR) or 25 °C (Pearleye P-007 LWIR). Use for e.g. a temperaturecontrolled air-flow housing.
Camera interfaces Figure 7: Frame-sync output (Pearleye P-030 LWIR) Pearleye P-007 LWIR Pearleye P-030 LWIR The frame-sync output (active low) supplies approx. 900 mV at a termination with 75 . Conversion of image data to temperature data Due to the internal LUT, the pixel information can be converted to a corresponding temperature value.

Camera interfaces The following diagram shows the result: Figure 9: Conversion of image data to temperature data: Pearleye P-030 LWIR Consideration of the emission ratio Every material has its own emissivity value for IR, so the measured value is not equal to the real temperature. The best result can be reached with materials that have emissivity ratio near to 1.0 (100%).
Camera interfaces Note Normally the background temperature can be assumed to be equal to the environmental temperature. The emission grades of many different materials can be found on various internet sources. Pearleye Technical Manual V2.3.
Camera interfaces GigE interface The Pearleye P-007 LWIR / Pearleye P-030 LWIR cameras are equipped with a 1000Base-T Ethernet interface (RJ45 (8P8C) connector). The data connection between camera and PC can be established via a standard patch cable of category 5e or better. Note For more information see the Pleora iPORT PT1000-VB Documentation.
Image processing Image processing This chapter explains the function of the Pearleye P-007 LWIR / Pearleye P-030 LWIR firmware. It is related to the individual modules of image processing and shows how the user can control these modules via the serial interface. Image processing chain The uncorrected sensor image from the microbolometer sensor is very inhomogeneous and each sensor element has its own characteristic curve. Therefore an individual adjustment of each pixel is necessary.
Image processing modules and the corresponding correction data is applied. Some modules may also write back new data to the correction memory: But currently the modules write back only to the SDRAM and not to the non-volatile flash memory.
Image processing Correction data Ex factory camera specific correction data for each correction module are determined and stored in the camera so that an optimum image quality is available. A PC with a Gigabit Ethernet interface can transmit the temperature data directly to the main memory or rather to the display.
Image processing Note For more information see Chapter Upload a file to flash (Q) on page 61. Short introduction: Two-point correction (A, B, E, J, K, N) The two-point correction is the most elaborate correction module of the Pearleye P-007 LWIR / Pearleye P-030 LWIR camera models. For this reason initially a general survey of the two-point correction functioning shall be given. Note For more information see Chapter Basic parameters and commands on page 39.
Image processing Figure 12: Two-point correction The reference images are stored in several files within the flash and are directly transferred into the correction memory following the camera start-up. The parameter A indicates the file number of the correction image at low reference temperature TA. The parameter B serves the same purpose for the reference image at temperature TB.
Basic parameters and commands Basic parameters and commands This chapter illustrates the basic configuration options and general commands available for the user, being important for the operation of an ex factory preconfigured camera. Most probably the information stated here will be sufficient for most users. Note For more information see Chapter Advanced parameters and commands on page 46.

(S= command) Table 10: GigE feature: CorrectionDataSet Automatic calibration (k) Beside the manual selection of data sets with parameter S also an automatic calibration (one-time or timer controlled repeating) can be carried out. The automatic process tries to determine the best data set S and activates it.
Basic parameters and commands GigE feature name (CameraSpecialFeatures) Feature Visibility Description AutoCalibrateOnce Beginner Start the automatic calibration once. (k=0 command) The processing of this command can take several seconds, depending on the current image rate and the number of correction data sets available.

Basic parameters and commands Electromechanical shutter (I) The Pearleye P-007 LWIR / Pearleye P-030 LWIR models are equipped with an electromechanical shutter that can be controlled with the command I. Use I=1 to close and I=0 to open the shutter. Note The shutter is open by default (power off). The typical life time of the electromechanical shutter is: 1 million control cycles.

Basic parameters and commands Show help text (?) The command ?=1 shows a command reference text at the serial terminal. It lists a short description for each command available in the firmware. Note This function is not available as GigE Vision feature. Note The displayed command reference is for both: AVT Goldeye and AVT Pearleye camera families. See the command reference to verify, if a command is valid for your camera model: Chapter Command reference on page 65. Pearleye Technical Manual V2.3.
Advanced parameters and commands Advanced parameters and commands This chapter describes the advanced configuration of the Pearleye P-007 LWIR / Pearleye P-030 LWIR models. Note In most cases the factory setup of the camera is sufficient. Only in special cases you need the advanced parameters and commands.
Advanced parameters and commands Value Description 2 Deactivated Test mode: Correction data A are output as image data. (*) 3 Deactivated Test mode: Correction data B are output as image data. (*) 4 One-point correction: Simple subtraction of the correction data A from the input data. In addition the set value J is added as offset to each pixel value. 5 One point correction: Simple subtraction of the correction data B from the input data.

Advanced parameters and commands page 39) actually being activated. Following the storage (X=1) and a re-start of the camera all file numbers following A and B are loaded into the correction data memory as mentioned above. For an optimum image quality one should take into consideration that the parameters A and B shall always specify a pair of two mating reference images, even though these parameters are alterable separately.

Advanced parameters and commands Background correction (U, M) The module background correction is closely related to the module integrator / image store at the beginning of the processing chain (H). It also comprehends an image integration function. But additionally it can subtract its current correction data image (H/U) from the incoming image and add the offset M. Thus a fixed pattern noise reduction or difference image calculation is possible.
Advanced parameters and commands U 0 Operation Mode Background Correction F E D C B A 9 8 7 6 5 4 3 2 1 0 - - - - - - - - c - - a b b b a ro Bit group Value (hex) a b c rw rw rw rw rw Explanation 0 Output: deactivated. Data is passed through transparently. 1 Output: activated. Apply the current correction image (H/U) and offset value M. 2 Output: activated. Output of current correction image (H/U). 0 Integration: deactivated.
Advanced parameters and commands The parameter M defines the offset value that is added to each pixel if the background correction is activated. Depending on settings of parameter j, M is automatically set to the mean value of the background image, provided that the background image acquisition is done with the automatic calibration function (k). In this way it is possible to preserve the constant component of the image irrespective of the background correction’s activation state.
Advanced parameters and commands Bad pixel correction (C, F) The configuration of the bad pixel correction is executed ex factory, so normally no access on the part of the user is necessary. The bad pixel correction applies up to six non false neighbor pixels, in order to determine an interpolated value from the neighbors. At the position of the defective pixel an interpolated value in exchange of the bad pixel value is output. The parameter F controls the operation mode of the bad pixel correction.
Advanced parameters and commands GigE Vision feature name Description BPC_OperationMode Operation mode of the bad pixel correction. (F= command) BPC_CorrectionData_FileNumber File number of the correction data for the bad pixel correction. (C= command) Table 25: Camera special feature: BadPixelCorrection Temperature drift compensation (m, n, o, p) The output data of a microbolometer system is highly affected by the temperature of the camera.
Advanced parameters and commands Note This function is currently not available as GigE Vision feature. Look-up table (LUT) (D, G) The temperature data of the microbolometer sensor is generally non-linear. The LUT linearizes the data that have already been pre-corrected by two-point, background and bad pixel correction, resulting in more exact temperature values. The LUT is implemented as 12-bit LUT. The operation mode of the LUT is controlled with parameter G.
Advanced parameters and commands GigE Vision feature name Description LUT_OperationMode Operation mode of the LUT. (G= command) LUT_CorrectionData_FileNumber File number of the data for the LUT. (D= command) Table 28: Camera special feature: LUT Integrator and image store (H) The integrator / image store (integrator) module is internally applied for the automatic selection of the correction set (k=) and the recording of new temporary reference image data (A=FF, B=FF).

Advanced parameters and commands Save parameters in flash (X) The command X=1 stores all parameter values into a system file within the flash memory. After restarting the camera they are automatically restored. However, neither new recorded correction images, nor modified set values (J and K for all valid S) are stored and will therefore be lost after the camera is switched off. GigE Vision feature name Description SaveParameterToCameraFlash Saves the parameters into internal camera flash memory.
Advanced parameters and commands Command Description l=1 List actually stored file numbers. d= Delete the file with the specified file number. v= View file. Dumps all bytes of the specified file to the serial interface. Q= Upload a file and store it in the Flash memory. Table 33: File system commands Note For more details see Chapter Command reference on page 65.
Advanced parameters and commands The character sequence is divided into the following parts: Part Description Nnnnnnnnn n = file size in bytes – 1. Creating a file of size 0 is not specified. Sttmm t = file type (any between 01 and FE) m = transmit mode (always 00) [PAUSE] To prevent an overflow of the input buffer, a pause of at least one second is mandatory. The file system needs time to open the file and delete the data of a potentially existing file.
Advanced parameters and commands Note • • • Large files may take a while for output. For an easy access to the file system AVT also offers a Windows application (File manager) that can be used to upload files. This is also included in the AcquireControl application and can be started by command [CTRL+F]. All file operations are not available via GigE Vision features. Pearleye Technical Manual V2.3.
Appendix Appendix Command reference This chapter describes the general command reference of the Pearleye P-007 LWIR / Pearleye P-030 LWIR firmware. It can be output to the camera’s serial interface by sending the command ?=1. Note This firmware is used in other camera models as well. Thus not all commands and parameters mentioned in this reference are useful in conjunction with the Pearleye P-007 LWIR / Pearleye P-030 LWIR.
Appendix At the beginning of a command sequence it is good practice to check the serial communication by sending just a [CR] to the camera and verify that the command prompt ">" is returned. There is an input buffer holding a few characters but no hardware handshake. Thus a sequence of commands should not be send to the camera without awaiting the intermediate input prompts. Otherwise the camera’s serial input buffer may overflow.

Appendix correction. Changing this parameter or the contents of the specified files may void ex factory calibration. 0 : No loading of any correction image.

Appendix shares its memory with the background correction (U=). This means that a new captured image with the command H= overwrites the current image of the background correction. The difference between H= and U= is the position in the image processing chain: H integrates and outputs data always at the beginning of the chain, which is uncorrected camera raw data. U operates behind the two point correction and thus integrates the data output of the two point correction (see E=).
