  • Page 31: Switches

    Teledyne Vision Solutions Switches Switches offer a range of functions and performance grades, so care must be taken to choose the right switch for a particular application. A switch is required if the sensor-to-PC separation is greater than 100 meters. It is recommended to test network device performance since certain devices may not achieve acceptable results in actual operation (depending on the device manufacturer’s implementation).

  • Page 32: Installation

    Teledyne Vision Solutions Installation All 3D sensors of the Z-Trak family require proper setup to produce correct measurements. The installation consists of the physical setup, software setup and network connection. Please review the following sections as they include information and advice on how to install your device. Physical Setup A 3D sensor is generally used with moving objects, but some setups require the sensor to move instead of the objects.
  • Page 33 Teledyne Vision Solutions REAR FRONT Figure 8. The laser sheet must be perpendicular to the scan direction. • The target object must be within the measurement area (see Figure 6) to obtain valid measurement results. • The 3D sensor is designed to dissipate heat through its housing. As such, ensure that it is mounted on a heat conductive metallic structure and that the entire surface of one of the sides of the housing makes full contact with the conductive surface.

  • Page 34: Mounting The 3D Sensor

    Teledyne Vision Solutions Mounting the 3D Sensor Planning Machine Opening Space Connector length, cable bend radius, enclosure height (height of casing), working distance, and height of the measurement area determine the minimum machine opening required for installation. The figure below depicts the machine opening space required for an object placed within the measurement area. The height should be calculated so that the object remains within the measurement area.

  • Page 35: Planning For Scan Direction And Profiler Orientation

    Teledyne Vision Solutions Figure 11. Depth depends on the body (enclosure) length and connector height. The dimensions of the machine opening required for setup are determined as follows: H max = enclosure height + standoff distance + Z range W min = Far FOV width D min = enclosure length + connector height The enclosure height, standoff distance, Z range, and Far FOV width are features that can be found using Z- Expert, in the Data Output category, under AOI.

Profiler orientation, assuming a forward scan direction, is as follows: • Normal: the object moves from the front to the rear of the sensor body. •...

  • Page 37: Planning For Unwanted Light Reflection Or Obstructed View

    Teledyne Vision Solutions NOTE Note that scan direction and profiler orientation are independent of each other. Scan direction and profiler orientation features are found in the Data Output category in Z-Expert. Planning for Unwanted Light Reflection or Obstructed View Acquiring quality profiles entails planning for unwanted laser light reflections or acquisition blockages. The following examples depict a few potential issues to consider.
  • Page 38 Teledyne Vision Solutions Figure 15. The form of the object blocks the sensor from seeing the laser. Objects made of reflective surfaces Scanning reflective surfaces and oddly angled surfaces may scatter the laser light, making it difficult to obtain a clean line profile.

  • Page 39: Controlling Ambient Illumination

    Teledyne Vision Solutions Controlling Ambient Illumination Over its image sensor window, the profiler uses a narrow bandpass optical filter that is tuned to the laser wavelength (color) of the model. This allows the 3D sensor to be used in most ambient light conditions without any measurement interference.

    Teledyne Vision Solutions Powering a Single Z-Trak Using PoE+ A PoE+ injector or a PoE+ Ethernet switch can be used to power the device. The picture below uses a PoE+ Ethernet switch. One or more units can be powered through a PoE+ switch. For additional details see Cables and Accessories.

  • Page 41: Powering Multiple Z-Trak2 2K Or Z-Trak Lp2C 4K Sensors

    When possible, use the same power source for the PC and the Z-Trak profilers. For example, when using Teledyne DALSA’s industrial products like GEVA-4000, GEVA-400 or VICORE that use 24 V DC as power source, we highly recommend powering the GEVA and the Z-Trak sensors with the same power supply.

  • Page 70: Improving The Quality Of Scans

    Teledyne Vision Solutions Improving the Quality of Scans The quality of a scan can be affected by factors such as overexposure or underexposure, and may lead to artefacts like false reflections. While some false reflections may be caused by the object itself or its surroundings, others are inherent to the triangulation technique used in 3D laser line sensors.
  • Page 71 Teledyne Vision Solutions Example 2: To scan with square pixels of 50 µm In this scenario, the range image presents "square pixels" in the X and Y directions, namely, the distance between X samples (along the laser line) is the same as the displacement between measurements in Y (i.e., distance between 2 consecutive profiles).

  • Page 72: Maximizing Profile Rate

    Teledyne Vision Solutions Maximizing Profile Rate Use the Profile Intensity > Info-Profile Rate Optimization subcategory to guide you on how to optimize the profile rate for the current configuration. Typical suggestions are: • Decrease the Measurement AOI Height. Decreasing the height means there is less data per profile to transfer.

  • Page 74: Multi-Sensor Systems

    Teledyne Vision Solutions Multi-Sensor Systems Several Z-Trak 3D sensors may be configured over or around an object to enlarge the measurement area, measure different areas of interest, or eliminate occlusion. In some cases, profile acquisition may be triggered synchronously or in sequence between sensors. In other cases, a larger, unified measurement space (UMS) can be created, such that all sensors report measurements in the same coordinate system.
  • Page 75 Teledyne Vision Solutions When synchronizing sensors, one is chosen as the primary (master) sensor, which responds to the external signal; the others are the secondary (slave) sensors. In each secondary sensor, the Trigger Start Source parameter is set to Multi Sensor Sync, indicating that the sensor will acquire profiles when it receives messages from the primary.

  • Page 76: Sync Group Delay Setting

    Teledyne Vision Solutions Sync Group Delay Setting To avoid missed profile triggers, the Sync Group Delay setting must not be too small. The optimal value for this feature depends mainly on network characteristics such as network link speed, packet size and number of switches.

  • Page 77: Example: Alternating Exposure Between Sensors

    Teledyne Vision Solutions Recall: • Secondary (slave): device whose Trigger Start Source parameter is always set to multi-sensor sync. • Primary (master): device whose Trigger Start Source parameter is not set to multi-sensor sync. The primary generates the messages that synchronize the secondary sensors. Sequential Exposure Simultaneous Exposure (alternating exposure between sensors)
  • Page 78 Teledyne Vision Solutions To add a delay between sensors during acquisition 1. On both sensors do: a. Open the Profile Intensity node and set features as indicated: • Laser Activation = Strobed • Profile Exposure Time = 500 b. Open the Multi-Sensor Sync node and set Sync Mode = On. 2.

  • Page 79: Unified Measurement Space (Ums)

    Teledyne Vision Solutions Unified Measurement Space (UMS) Each 3D laser profiler sensor has its own measurement space; the data acquired by a unit is relative to the unit. Combining the data from several sensors in different poses can be used to provide a more complete representation of an object.
