    4 Functionality 4.3.4 Multiple Regions of Interest The MV1-D1312(IE/C) camera series can handle up to 512 different regions of interest. This feature can be used to reduce the image data and increase the frame rate. An application example for using multiple regions of interest (MROI) is a laser triangulation system with several laser lines.
  • Page 55 Figure 4.23: Multiple Regions of Interest with 5 ROIs Fig. 4.24 shows an example from hyperspectral imaging where the presence of spectral lines at known regions need to be inspected. By using MROI only a 656x54 region needs to be readout and a frame rate of 4300 fps can be achieved.

  • Page 61: Trigger And Acquisitionmode

    4.4.3 Trigger and AcquisitionMode The relationship between AcquisitionMode and TriggerMode is shown in Table 4.12. When TriggerMode=Off, then the frame rate depends on the AcquisitionFrameRateEnable property (see also under Free running in Section 4.4.2). The ContinuousRecording and ContinousReadout modes can be used if more than one camera is connected to the same network and need to shoot images simul- taneously.

Acquisition can be stopped by executing AcquisitionStop command. Continuous Camera is ready to accept triggers according to the TriggerSource property. Acquisition and trigger acceptance can be stopped by executing AcquisitionStop command.

  • Page 63: Exposure Time Control

    4.4.4 Exposure Time Control Depending on the trigger mode, the exposure time can be determined either by the camera or by the trigger signal itself: Camera-controlled Exposure time In this trigger mode the exposure time is defined by the camera. For an active high trigger signal, the camera starts the exposure with a positive trigger edge and stops it when the preprogrammed exposure time has elapsed.

  • Page 65: Trigger Delay

    The timing of the rising edge of the trigger pulse until to the start of exposure and strobe is equal to the timing of the camera controlled exposure time (see Section 4.4.4). In this mode however the end of the exposure is controlled by the falling edge of the trigger Pulsewidth: The falling edge of the trigger pulse is delayed by the time t which is results from the d iso input...

    4.11 Image Information and Status Line (not available for DR1-D1312(IE)) There are camera properties available that give information about the acquired images, such as an image counter, average image value and the number of missed trigger signals. These properties can be queried by software. Alternatively, a status line within the image data can be switched on that contains all the available image information.

    4.12 Test Images Test images are generated in the camera FPGA, independent of the image sensor. They can be used to check the transmission path from the camera to the frame grabber. Independent from the configured grey level resolution, every possible grey level appears the same number of times in a test image.

On the other hand, a non-flat histogram (Fig. 4.62) indicates problems, that may be caused either by the a defective camera or by problems in the grabbing software.

    4 Functionality 4.13 Double Rate (DR1-D1312(IE) only) The Photonfocus DR1 cameras use a proprietary modulation algorithm to cut the data rate by almost a factor of two. This enables the transmission of high frame rates over just one Gigabit Ethernet connection, avoiding the complexity and stability issues of Ethernet link aggregation. The algorithm is lossy but no image artefacts are introduced, unlike for example the JPEG compression.

  • Page 112: Calibration Of The Fpn Correction

    6 Software 6.5 Calibration of the FPN Correction The following procedures can be most easily done with the PF_GEVPlayer. 6.5.1 Offset Correction (CalibrateBlack) The offset correction is based on a black reference image, which is taken at no illumination (e.g. lens aperture completely closed). The black reference image contains the fixed-pattern noise of the sensor, which can be subtracted from the live images in order to minimise the static noise.

  • Page 113: Storing The Calibration In Permanent Memory

    The procedure to calibrate the offset correction (see Section 6.5.1) must be run just before calibrating the gain correction. Don’t turn off the camera between the calibration of the offset correction (Cali- brateBlack) and the calibration of the gain correction (CalibrateGrey). Illuminate the camera homogeneously to produce a gray image with an Average_Value (in category PhotonfocusMain) between 2200 and 3600 DN.

  • Page 115: Mroi

    6.7 MROI The MROI feature is described in Section 4.3.4. This section describes how to set the MROI values. When MROI is enabled, then the camera internally processes the MROI entries sequentially, starting at MROI_Index 0. The processing is stopped when either the last MROI_Index is reached or when an entry with MROI_Y=1081 is reached.
