    4.5 Dimensions The sensor can be mounted with either M8 or 5/16" hardware. Provision to adjust the position and orientation of the sensor to align its laser plane with the laser planes of the other sensors in the ring is recommended. Although this alignment is not required for reliable profile data (adjacent sensors typically scan during different time slices), aligned laser planes provide a better appearance to the end user of the system.

  • Page 19: Cleaning

    4.7 Cleaning The windows on a sensor must be kept clean and free of debris at all time. If the windows become dirty, clean them with an ammonia-based cleaner only. 4.8 Features The chroma+scan 20X0 is the new-generation, high-speed, high-density 3D profile scanning system for primary log optimization.

  • Page 20: Binocular 3D Scanning

    4.8.1 Binocular 3D Scanning The chroma+scan 20X0 sensors incorporate a dual camera design which places cameras symmetrically about the laser plane. The two cameras provide binocular 3D profile scans that eliminate occlusions due to protruding features. This avoids data dropouts that would occur with conventional single amera sensors.

  • Page 23: Scan Frame

    5.3 Scan Frame A typical scanner arrangement is a ring of four, chroma+scan 20X0, sensors in an "X" configuration. However, different configurations and multiple rings can be employed as needed to suit the application. Currently, Detection Mode only supports a single ring of sensors. The scan frame mechanically supports the sensors, and should provide a means of adjusting the location and orientation of each sensor so that their laser planes can be aligned.

  • Page 24: Calibration Target

    5.4 Calibration Target The system calibration target is required to perform a system calibration. This process locates each sensor with respect to a global coordinate system defined relative to the target. Transformation parameters for each sensor in the system are acquired during the system calibration process and are used by the Station to transform profile data from the multiple sensors into a single coordinate system aligned with the downstream log processing equipment (eg saws, chipper heads).

  • Page 25: Software

    Section 6 6 Software 6.1 Overview The user's Client, running on the host computer, communicates with a Server, running on the FireSync Station, using the FireSync Host Protocol. This is described in the FireSync Host Protocol Reference Manual. This section describes the FireSync Client, and the Client Interface.

  • Page 26: Firesync Client (Complete)

    The FireSync Client application is available for Windows XP. Obtain the software from LMI Technologies Downloads site and install it on a suitable Client machine. The Client machine should have a Gigabit Ethernet adaptor that can be configured for a static IP address.

  • Page 27: Server Configuration

    Once the upgrade is complete, the entire system must be power cycled. After this is performed, reconnect with kClient. Follow this procedure whenever a firmware update is released by LMI. 6.2.4 Server Configuration The FireSync station ships from LMI empty, with no settings files. The very first time the client connects to the station, it detects that there is no settings file and displays the Setup tab when selecting the Server node in the device tree.
  • Page 28 Select an individual sensor to bring up its configuration tabs, and then select the Setup tab. A sensor has an orientation, a multiplex time slot, and is viewing a particular vertex of the system calibration target. Orientation is a value that can be 0 or 1. This indicates the sensor's orientation relative to the scanning direction.

    The dead zones will be committed to the sensor when the system is stopped by pressing the Stop button. Make sure there is no object in the scanner frame before enabling this feature. To remove all dead zones from a sensor, set the slider to 255, and then press Stop to commit an empty bit mask to the sensor.

  • Page 31: Calibration Mode

    6.2.7 Calibration Mode In order to receive data from all sensors in a common world coordinate frame, a system calibration has to be performed. This is done by placing a system calibration target, with a given shape and location, in the scanner frame. Each sensor has to view a specific vertex (or corner) of the target and this has to be specified in the Setup tab for each sensor before performing the system calibration.
  • Page 32 A more detailed status report is shown under the Status tab, where serial numbers of sensors, together with error codes, are reported in case of calibration failure. Following is a description of error messages. If any other explicit error code is reported by the system, please contact LMI for support.

  • Page 33: Detection Mode

    6.2.8 Detection Mode Select the server in the device tree, and then select the Detection tab. Note that system calibration has to be performed first, in order for Detection Mode to run. Before running the system, enter values for the five parameters needed for the Detection Mode: Output Batch Count is number of profiles batched together in a single message.
