  • Page 33 4.2 3D Features Triangulation Setup 3 In this setup the laser line generator and the camera are placed in a more reflecting configuration.

  • Page 40: Peak Filter

    4 Functionality 4.2.10 Peak Filter Peaks that are detected by the PeakDetector 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 occured. Filtering peaks might increase the robustness of the 3D application by filtering peaks that were caused by unwanted effects, such as reflections of the laser beam.

  • Page 48: Image Acquisition

    4 Functionality 4.4 Image Acquisition 4.4.1 Readout Modes The MV1-D1312 CMOS cameras provide two different readout modes: Sequential readout Frame time is the sum of exposure time and readout time. Exposure time of the next image can only start if the readout time of the current image is finished. Simultaneous readout (interleave) The frame time is determined by the maximum of the exposure time or of the readout time, which ever of both is the longer one.
  • Page 49 4.4 Image Acquisition In simultaneous readout mode image output faces minor limitations. The overall linear sensor reponse is partially restricted in the lower grey scale region. When changing readout mode from sequential to simultaneous readout mode or vice versa, new settings of the BlackLevelOffset and of the image correction are required.

    5 Hardware Interface 5.5 Trigger and Strobe Signals for GigE Cameras 5.5.1 Overview The 12-pol. Hirose power connector contains two external trigger inputs, two strobe outputs and two differential inputs (G2 models: RS-422, H2 models: HTL). All inputs and outputs are connected to the Programmable Logic Controller (PLC) (see also Section 5.6) that offers powerful operations.

    5.5 Trigger and Strobe Signals for GigE Cameras 5.5.2 Single-ended Inputs ISO_IN0 and ISO_IN1 are single-ended isolated inputs. The input circuit of both inputs is identical (see Fig. 5.3). Fig. 5.5 shows a direct connection to the ISO_IN inputs. In the camera default settings the PLC is configured to connect the ISO_IN0 to the PLC_Q4 camera trigger input.

    5 Hardware Interface 5.5.3 Single-ended Outputs ISO_OUT0 and ISO_OUT1 are single-ended isolated outputs. ISO_OUT0 and ISO_OUT1 have different output circuits: ISO_OUT1 doesn’t have a pullup resistor and can be used as additional Strobe out (by adding Pull up) or as controllable switch. Maximal ratings that must not be exceeded: voltage: 30 V, current: 0.5 A, power: 0.5 W.

    5.5 Trigger and Strobe Signals for GigE Cameras 5.5.6 I/O Wiring The Photonfocus cameras include electrically isolated inputs and outputs. Take great care when wiring trigger and strobe signals to the camera, specially over big distances (a few meters) and in noisy environments.
  • Page 96 5 Hardware Interface Common Grounds with Star Wiring Ground loops can be avoided using "star wiring", i.e. the wiring of power and ground connections originate from one "star point" which is typically a power supply. Fig. 5.14 shows a schematic of the star-wiring concept. Fig.
  • Page 97 5.5 Trigger and Strobe Signals for GigE Cameras Fig. 5.16 shows an example of how to connect a flash light and a trigger source to the camera using star-wiring. The trigger in this example is generated from a light barrier. Note how the power and ground cables are connected to the same power supply.
