    Image Acquisition This chapter gives detailed information about the controlling of the image acquisition. It shows how the camera can be triggered or run in free-running mode, and how the frame rate can be configured. The structure offers a lot of flexibility in the configuration. It follows the GenI- Cam naming convention.

    4 Image Acquisition Acquisition Control The acquisition control block takes care of the acquisition function. The camera can only capture frames, when the acquisition has been started and is active (see Section 4.2 for more information). Frame Control The frame control block takes care of the capturing of one or many frames and burst of frames (see Section 4.3 for more information).

A valid trigger signal on the selected trigger source starts the counter, which means, that it counts the predefined number of events from the start value according to the counter start value and duration configuration.

  • Page 41: Counter Event Source

    5.1 Counter Counter Trigger Source Off The state of the counter changes to "trigger wait". The counter reset source can be set to the counter end signal of the same counter. This allows to restart the counter automatically as soon as it arrives its end condition.

    User Storage Photonfocus Cameras provide the user with access to an internal storage that can be used for example for calibration purposes. This can be especially useful for example for 3D applications, or any 2D applications that require calibration on a per-camera basis. The storage can be accessed in two different ways: through the UserStorage_Address1B and the UserStorage_Data1B or UserStorage_Address4B and UserStorage_Data4B.

  • Page 59: Image Format Control

    Image Format Control The focus on the interesting parts of an image can be set by setting the region of interest (ROI) (see Section 10.2). The ROI influences the image size which leads into an increased frame rate (see Chapter 11 for more information about the available frame rate).

  • Page 61: Frame Rate

    Frame Rate The frame rate depends on the image size, the used exposure time and the max data rate of the GigE interface (MaxDataRateInterface). The image size is given by the image size, which can be configured by the ROI, MROI and decimation settings (see Chapter 10). Two different timing situations has to be considered: •...

    High Dynamic Range Mode (HDR) To have an accurate laser line detection it is important that the pixels that represent the laser line, are not saturated. The High Dynamic Range (HDR) mode is a special integration mode that increases the dynamic range of the pixels, and thus avoids the saturation of the pixels in many cases.

  • Page 68: Column Fpn Correction

    13 Image Data Processing 13.2 Column FPN Correction Due to the readout structure of the image sensors there is a column-wise fixed pattern noise (FPN). The Column FPN Correction (ColCorrection) adds or subtracts a fixed value to a column. These values are obtained by a calibration process. The ColCorrection of the camera was calibrated at Photonfocus production facility.

  • Page 69: Storing The Calibration In Permanent Memory

    13.3 Gain and Offset Column noise changes with different analog gain settings. The column FPN cor- rection of the camera needs to be recalibrated when the analog gain setting is changed. 13.2.3 Storing the calibration in permanent memory After running the calibration procedure (see Section 13.2.2) the calibration values are stored in RAM.

  • Page 71: Laser Line Detection

    13.5 3D Features The accuracy of the triangulation system is determined by the line extracting algorithm, the optical setup, the quality parameters of the laser line generator and the parameters of the lens which makes optical engineering necessary.

    13 Image Data Processing 13.5.9 Transmitted data in 3Donly mode In 3Donly mode only the 3D data is transmitted. The FrameCombine feature (see Section 13.5.10) was added to lower the transmitted frame rate. For FrameCombine = f, the data for f images are combined into one image.

  • Page 81: 10Frame Combine

    13.5 3D Features 13.5.10 Frame Combine Very high frame rates that are well over 1000 fps can be achieved in 3Donly mode. Every frame (image) activates an interrupt in the GigE software which will issue a high CPU load or the frame rate can not be handled at all by an overload of interrupts.
  • Page 82 13 Image Data Processing FrameCombine_ForceTimeout The transmission of the combined frame is forced by writing to the FrameCombine_ForceTimeout property. When the FrameCombine is finished by a timeout, then the remaining data in the combined frame will be filled with filler data: the first two pixels of every filler row have the values 0xBB (decimal 187) and 0x44 (decimal 68).

    13.5 3D Features 13.5.11 Peak Filter Peaks that are detected by the LineFinder algorithm can be filtered by applying the parameters described in this section. A filtered peak appears as all 3D data set to 0, which is the same as if no peak occurred.

Depending on the geometrical setup of the camera and the lasers, a bigger object height may be indicated by either a smaller or larger position.

    13.7 Test Images 13.7 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 acquisition software. Independent from the configured grey level resolution, every possible grey level appears the same number of times in a test image.

    Mechanical Considerations 16.1 Mechanical Interface During storage and transport, the camera should be protected against vibration, shock, moisture and dust. The original packaging protects the camera adequately from vibration and shock during storage and transport. Please either retain this packaging for possible later use or dispose of it according to local regulations.

  • Page 124: Camera Runs In Triggered Mode

    C Use Cases • In FrameRateControlled acquisition mode the max configurable exposure time depends on the configured frame rate. When the user increases the frame rate, the camera decreases the exposure time automatically if necessary. C.1.3 Camera runs in triggered mode The camera can be triggered by a software or hardware signal.

  • Page 125: Triggered Controlled Exposure Mode

    C.1 Acquisition The number of frame within a burst must be set by parameter AcquisitionBurstFrameCount parameter. Set the parameter EnAcquisitionFrameRate to False if the frames within a burst must be acquired as fast as possible. If the frames within a burst must be acquired with a certain speed, set the parameter EnAcquisitionFrameRate to True and configure either AcquisitionFrameTime or AcquisitionFrameRate accordingly.

  • Page 126: Timer

    C Use Cases C.2 Timer There are four general purpose timers available. The following sections show some use cases, how the timers can be used. C.2.1 Strobe Signal Output The timer can be used to generate a pulse with a certain width on the LineOut output together with every exposure cycle in order to control an external light.
