Camera interfaces Camera interfaces This chapter gives you information on the control interface, inputs and outputs and trigger features. www For accessories like cables or power supply see: http://www.alliedvisiontec.com/emea/products/accessories/camera-link.html Requirements and serial I/O Frame grabber requirements Take special care in selecting the Camera Link frame grabbers. They should be able to process the 10 taps of each Bonito channel at 80 MHz clock frequency.
Camera interfaces Camera link cable length The tested maximum Camera Link cable length for the Bonito is 7 m, depending on the cable quality and the frame grabber. Accessories The Bonito needs a DC power supply with 12 V at an average current of 0.35 A (max. 0.4 A). The camera is delivered with suitable power supply without power cord. The Bonito is available with C-Mount, F-Mount or EF-Mount lens adapter. Consider the CMOS sensor size for lens selection.
Camera interfaces The baud rate is factory-set to 115200 but can also be configured to other values: see chapter Serial control interface configuration (s) on page 66. All command examples are formatted in the following styles: • Bold Courier font: characters sent to the camera • Courier font: the camera’s answer At power-up the camera loads the stored parameter configuration from its nonvolatile memory and sends a start message after successful initialization to all activated serial interfaces.
Camera interfaces 3. A terminal program without local echo displays E=3E8 > After the execution of the command has finished the command prompt character > is displayed again. If any error occurred, a question mark character ? is sent previous to the prompt character.
Camera interfaces Camera I/O connector pin assignment (15-pin D-sub connector) This connector is intended for supplying power as well as external input/output signals. Pin Signal 1 Direction Level External Power +12 V DC (+5%, to 10%), 0.35 A (4.2 W), max. 0.
Camera interfaces Synchronization output (pin 6) Note Only cameras with firmware CMC.040.01.07 or newer support this feature. If you use a camera with an older firmware version: don‘t connect pin 6. Use this signal for the following: • Synchronize external devices to the effective exposure of Bonito. Examples of external devices are flash lights, flash strobes or timer circuits. • Reduce the timing jitter of start and end point of exposure.
Camera interfaces Trigger input (pin 10-11) Figure 11: Trigger input diagram The current through the optocoupler’s LED should be in the range from 5 mA to 15 mA. This is the case if 5.0 V ≤ Vin ≤ 12 V. Note If you use higher voltages, you have to connect externally an additional current limiting resistor. A rising edge at this optocoupler input starts the exposure.
Camera interfaces This is an open collector optocoupler output. The transistor is conductive during the active exposure time of the image sensor. The optocoupler adds an intrinsic delay to the signal. The power dissipation through the optocoupler’s transistor must not exceed 150 mW. A typical value for the external pull-up resistor is R = 4700 . This ensures riskfree operation to the upper Vcc limit. Note This output is not recommended for new system designs.
Camera Link interface (01-04 or CL1, CL2) Camera Link interface (01-04 or CL1, CL2) Camera Link is an interface for the transmission of digital video data. The standard defines data transfer on a physical base and determines connectors, cables and components for transmission and reception. Three different configurations (base, medium and full) are available, distinguished by the number of transmitter–receiver pairs (one, two or three respectively).
Camera Link interface (01-04 or CL1, CL2) Each channel delivers ten Camera Link ports labelled A to J. Every port has eight bits and is assigned to a corresponding sensor tap that outputs specific pixel columns of the image. Consequently, up to 2 x 10 = 20 simultaneous pixels are transferred to the frame grabber(s) in parallel per Camera Link clock cycle.
Camera Link interface (01-04 or CL1, CL2) Figure 14: Camera link connector: 10-tap pin assignment (O1/O3 or CL2 connector) Serial interface (SerTC, SerTFG) The Camera Link connectors O2 and O4 (Bonito CL-400B/C 200fps: connector CL1 only) each provide the asynchronous serial control lines SerTC and SerTFG. This is the preferred communication channel to control the various camera Bonito Technical Manual V2.3.
Camera Link interface (01-04 or CL1, CL2) functions. Both Camera Link serial interfaces (and also the third RS-232 interface at the 15-pin D-sub connector) are virtually equal. They all use one global baud rate setting. They also share the same receive buffer. Output characters (including echo) are always sent to all activated serial ports. The ports are not intended for concurrent activity, although it might be possible under particular circumstances.
Camera Link interface (01-04 or CL1, CL2) Reserve control input (CC2) The camera control signals CC2 at the Camera Link connectors O2 and O4 (or connector CL1) are reserved for future use. Pixel order Each frame in single channel mode (S=0, max. 193 full frames per second) is transmitted from top left to bottom right, line per line. The diagram below shows how the image is reconstructed from the ten Camera Link taps A – J.
Camera Link interface (01-04 or CL1, CL2) From the host’s point of view the Bonito behaves like two cameras with half of the possible image width. The host computer receives two images at the same time that are reconstructed in the order shown below. It is the duty of the system designer to allow for assembly of the two halves if the application demands it. Figure 16: Pixel order: half frame Bonito Technical Manual V2.3.
Camera Link interface (01-04 or CL1, CL2) Timing (FVAL, LVAL, PCLK) The Camera Link pixel clock frequency of the Bonito is 80 MHz. The 10-tap configuration transfers 10 pixels per clock cycle at once, or 20 pixels per clock cycle in the dual-channel mode). The synchronization signals LVAL (line valid) and FVAL (frame valid) are used to designate valid data output. Single channel mode The charts below illustrate the Camera Link timing for single channel mode (S=0), in continuous mode (M=0).
Camera Link interface (01-04 or CL1, CL2) Dual channel, full line length The charts below illustrate the Camera Link timing for dual channel mode (full line length, S=1), in continuous mode (M=0). The frame gap may vary in other trigger modes. Additionally, the number of active lines per frame can be configured by the user (parameter N). Note The diagrams displayed are not applicable for the Bonito CL400B/C 200fps cameras.
Camera Link interface (01-04 or CL1, CL2) Dual channel, reduced line length The charts below illustrate the Camera Link timing for dual channel mode (compatibility mode with reduced line length, S=3), in continuous mode (M=0). The frame gap may vary in other trigger modes. Additionally, the number of active lines per frame can be configured by the user (parameter N). Note The diagrams displayed are not applicable for the Bonito CL400B/C 200fps cameras.
Parameters and commands Parameters and commands This section explains the basic Bonito configuration parameters and general commands available to the user. Parameters and commands are communicated using the camera’s serial interface. For more information see chapter Serial I/O on page 22. Note In this section, all values and examples noted in monospaced font are denoted in the hexadecimal numbering system, if not otherwise noted. In all cases, explicit base notation (e.g.
Parameters and commands Secondary starting address (B) The value of parameter B is used to create the secondary region of interest (ROI2). If the double ROI mode is active, B defines the line of the image sensor that is the first line of the second half of the output image.
Parameters and commands • Send the following serial command to record and apply new correction data. The camera answers with a new prompt sign if the command has successfully completed. The execution lasts for the duration of some images. >C=1[CR] > Use the command C=3 to re-enable the FPN correction without acquiring new correction data. Instead, the correction data acquired by the last C=1 call will be used. However, correction data is not stored beyond power loss.
Parameters and commands Figure 23: Parameters relevant in double ROI mode The diagram illustrates the use of ROI parameters A, B, I, and N, from the sensor’s point of view. The sensor’s first (topmost) line has the address 0, the last (lowermost) line has the address 6BD.
Parameters and commands Related Parameters D, F, K, M, N and S. Frame duration must always be greater than exposure time. Example 1 K=53 (0x53 = 84), sets prescaler tick length to 84 clock cycles, which corresponds to 1.5 μs E=6BE (0x6BE = 1726), sets exposure time to 1726 prescaler ticks F=FA0 (0xFA0 = 4000), sets frame duration to 4000 prescaler ticks M=3 activate free-running exposure mode using E and F Result: exposure time = 1726 * 1.5 μs = 2589 μs frame duration = 4000 * 1.
Parameters and commands M=7 activate PIV and free-running exposure mode using E and F N=6BD (0x6BD = 1725), readout 1726 lines K=53 (0x53 = 83), sets prescaler tick length to 84 clock cycles, which corresponds to 1.5 μs E=1 set small exposure time, although PIV has no exposure control, the exposure time is needed to create valid internal timing sequence F=D7F (0xD7F = 3455), sets frame duration to 3455 prescaler ticks, Result: frame duration = 3455 * 1.5 μs = 5182.
Parameters and commands Related Example Parameters A, B, D, and N I=4 output every 4th line N=1AF (0x1AF = 431), sets number of lines to 431, which equals a quarter of the full image Synchronization output (J) Parameter J sends an output synchronization signal to pin 6 of the camera control connector.
Parameters and commands Timer prescaler value (K) The prescaler value is used to divide the basic timer clock frequency of 56 MHz by a value of (K + 1) down to a smaller clock frequency. The resulting frequency is utilized as the time base for exposure time E and frame duration F. This parameter is 16 bit wide. The implementation of this value provides flexibility between the maximum interval length, the smallest possible resolution, and the size of the numbers involved.
Parameters and commands Parameter Value Line Duration (S=0) tL = 3 μs Line Duration (S=1) tL = 1.5 μs Line Duration (S=3) tL = 1.
Parameters and commands Since all of the sub-fields are set using the parameter M, it is only possible to set all of them at the same time. The value of M is calculated as the aggregate sum of the hexadecimal values that are set to each of the three sub-fields. The table below shows the hexadecimal weights that can be set for each subfield. To work out the final value for M, select a setting for each sub-field, then add up the corresponding hexadecimal values.
Parameters and commands • • • Activates Image on demand mode (IOD) with exposure timer (weight = 2) Deactivates PIV mode (weight = 0) Activates Permanent exposure mode (weight = 20) M=2A (0x2A = 0b101010. This value is not recommended since bit #3 is set to 1 here, even though it is not used by the parameter.
Parameters and commands The next falling edge stops the exposure and starts the output of the image synchronized to the next line. Due to the line jitter the next rising edge of the trigger should not appear earlier than tFDmin + tL after the previous rising edge.
Parameters and commands E * tTR + tL, whichever is the bigger, after the previous rising edge.
Parameters and commands Figure 26: Exposure timing mode, M=3, flow diagram Parameter Value Trigger High Duration (Sync Pulse) tL < tTH < F * tTR – tL Exposure Jitter 0 < tj < tL Exposure Time tExp = E * tTR – tL± tj Frame Duration F * tTR ≥ max (tFDmin + tL , E * tTR + tL ) Table 15: Exposure timing mode, M=3, timing parameters PIV mode (bit group p) Particle Image Velocimetry (PIV) is a contact-free method for tracking and visualizing the movement of particles in liquids or gases that travel a
Parameters and commands Basic working principle of the CMOS sensor A basic understanding of the CMOS sensor‘s working principle is required to understand how the PIV mode of the Bonito operates. For that reason, a simplified short explanation is included below. Figure 27: Simplified diagram of the CMOS pixel architecture Each pixel of the sensor is a shutter pixel that includes a photo detector, a pixel memory, and a number of gates. The photo detector accumulates the charge produced by light (exposure).
Parameters and commands • Sets Exposure feature mode to Standard (weight = 0) For technical reasons, exposure control is not available in PIV mode, the exposure is permanently active (the reset gate in every pixel is always closed). This has two practical implications: • A synchronized pulsed light source is necessary in order to generate relevant images that can be evaluated. To generate contrast-rich images, ambient light has to be minimized. • To change the exposure time, change the frame rate.
Parameters and commands Internal charge transfer and readout The internal charge transfer of the first image is started with some fixed delay and it takes the time of one line duration (tL). The end of the charge transfer effectively terminates the exposure of the first PIV frame and internally starts exposure of the second PIV frame. During any charge transfer, the sensor‘s photo detectors keep integrating charge.
Parameters and commands The rising edge at synchronization output signalizes externally that the exposure of the first PIV frame has ended. This requires setting J=1, and may be used to trigger the second flash pulse. The recommended guard interval tG2 will be kept automatically. To move the second flash pulse closer to the first end of charge transfer, use an external timing device that is triggered by an external camera trigger or the previous falling edge of the synchronization output.
Parameters and commands • Sets the Exposure feature mode to Standard. (weight = 0) Even though the Exposure feature mode is set to Standard, not to Permanent Exposure mode, the exposure is always active, due to activation of the PIV mode. M=7 (0x7 = 0b111), sets the bit field to „- - 0 0 - 1 1 1“. • Activates Image on Demand mode (IOD) with exposure timer and frame duration timer mode (weight = 3) • Activates PIV mode (weight = 4) • Sets the Exposure feature mode to Standard.
Parameters and commands Parameter Value Trigger rate requirement (or equivalent frame duration setting F) tT > (2 * ((N + 1)+1)+1) * tL Trigger high duration requirement (or equivalent exposure time setting E) tTH < (N + 1) * tL tTH > 500 ns Table 16: PIV mode timing parameters - settings E and F depend on exposure timing mode setting of parameter M Parameter Value First trigger to end-of-chargetransfer delay tTD1 = tL + 250 ns (@ T=2, typical) First delay to end-of-chargetransfer tTD1 = tL + 1
Parameters and commands Standard mode Bit group: f Weight: 0 Enhanced full well (3T) mode Bit group: f Weight: 10 The full image shutter is not available in this mode. Instead, the sensor operates in rolling shutter mode, the effective shutter time equals the image duration. For that reason, a synchronized strobe light is recommended. Consequently, any exposure time setting controlled by Parameter E or by external signal is ignored.
Parameters and commands Parameter Value IOD IOD=0 if Continuous mode (e.g. M=0), IOD=1 if not in Continuous mode tL tL = 3 μs in single CL channel mode (e.g. S=0), tL = 1.5 μsin dual CL channel mode (e.g. S=1) Table 19: Parameters for fps calculation Range From 0 to 6BD Default 6BD Related Parameters A, B, D, I, and M Example 1 M=0 S=0 [tL = 3 μs] D=0 (not for Bonito CL-400B/C 200fps cameras) N (see table on next page) Setting No.
Parameters and commands Note • • Consider the number of lines in minimum frame duration calculations for the image on demand (IOD) mode. For more information about calculation of the minimum frame duration and dependent IOD mode timing constraints, see chapter Exposure control mode (M) on page 45. Camera Link output mode setting (S) The parameter S controls how the camera outputs pixel data to the Camera Link interface.
Parameters and commands Setting Function S=1 • Mode: Dual channel mode (not for Bonito CL-400B/C 200fps) • Frame rate: 386 fps • Line length: 2 x 1160 = 2320 pixels The image is split vertically into a left and a right half. Each half has a horizontal size of 1160 pixels and is output separately via its own Camera Link 80-bit channel. The left half travels via the left Camera Link channel at the connectors O2 / O1 and the right half travels via O4 /O3 respectively.
Parameters and commands Setting Function T=0 No input selected. T=2 Optocoupler OK1 at pins 10 and 11 of the control connector. T=3 CC1 at the Camera Link connector O2 or CL1 (default). T=4 CC1 at the Camera Link connector O4. (Others) Reserved for future use.
