    The measurement results are then stored in the system and transferred to the separate sScale™ server. After the transfer, changes to the measurement cannot be made to the sScale™ system in the forest nor the sScale™ server! NOTE: Use a digitiser pen with a thin plastic tip for all work on the monitor.

  • Page 22: Image Capture

    Note a maximum exposure duration of 10.0 ms! At a higher exposure, the individual pictures may blur when driving too fast and the system may fail to perform the analysis successfully. Above an exposure time of 10.0 ms use the LED floodlight. Figure 5: Too low, too high and correct exposure time TIP: Even during the day, the use of the built-in floodlight can be helpful.

  • Page 23: Check And Crop The Captured Picture Sequence

    CAUTION: Adjust your driving speed according to the nature of the path and the length of the woodpile. Before starting the measurement, watch out for oncoming vehicles or persons! The maximum possible vehicle speed is 20 km/h. For the prevention of accidents, however, it is recommended to drive past the woodpile at a speed of nor more than 15 km/h.

  • Page 25: How Precisely Does The Polygonal Course Need To Be Adjusted

    The user of the system is responsible for ensuring that the woodpile face area demarcation is sufficient to be bounded by the polygonal course. Dralle A/S can only guarantee that the area indicated later, within the measurement uncertainty, corresponds to the area covered by the polygonal course.

  • Page 29: Entering The Woodpile Id

    Only after a Woodpile ID has been entered by the user can a measurement be stored and sent to the sScale™ server. This Woodpile ID is independent of the internal, unique Woodpile ID. Entering the Woodpile ID is done via button 2.2.7.5 Woodpile ID”. After pressing the button, a QWERTY keyboard appears.

  • Page 30: Discarding A Measurement

    After pressing the button “Submit” the user interface “Start screen” appears automatically. NOTE: After saving the measurement, no change to the measurement is possible. Neither the polyg- onal course, nor other parameters (e.g., density or assortment lengths) can be changed after saving.

  • Page 31: Dividing A Woodpile

    3.3. Dividing a woodpile 3.3.1. Basics With very narrow road conditions, it may occur that a woodpile cannot be measured as a whole, since the camera opening angle cannot cover the entire wood piling height. In this case, the woodpile can be divided into an upper and a lower part. These are measured in two separate measuring runs, which leads to two separate woodpile measurement results.
  • Page 32 Figure 14: Polygonal course of the upper part of a divided woodpile Figure 15, Figure 16, Figure 17 and Figure 18: Detail views in the area of the cross-hairs CAUTION: For woodpiles longer than 20 metres, it is necessary to place additional marking crosses along the dividing line, in addition to the two edge crosses.

Thus, in the user interface “Result” (see Chapter A.2.2.7), conformity-rated results can be found alongside other, non-conformity-rated results. While the conformity-rated results are presented in full, the “Result”...

     a note (if entered) 4.2. Manual measurement Using sScale™, a manually measured woodpile can be entered and saved. You can find more detailed information in Chapter A.5.2.1. CAUTION: Results of manual measurements are non-conformity-rated For this reason, the results of a manual measurement are always displayed in white only and the reference to conformity-rated results is missing and/or is indicated by the following: “Man-...
  • Page 36 Figure 22: Result representation of a non-conformity-rated measurement in the user interface “Result” Figure 23: Result representation of a non-conformity-rated measurement in the user interface “Details of an archive entry” In most cases, a manual measurement is present if the woodpile could not be measured in a photo-optic manner (for example, repeated failure of the analysis because the woodpile is too small).

  • Page 37: Other Menu Functions

    Functions of the user interface “Main Menu” All the following functions can be accessed by calling up the main menu. This is done by pressing the sScale™ logo at the top left of the screen and can be done from any user interface. 5.1.1. Registrations By pressing the button 2.2.2.6 “Registrations”...

    Even if the system is shut down with measurements that have not yet been sent, this data will not be lost. Sending the results to the sScale ™ server may take some time, depending on your network connection.

  • Page 39: System Shut-Down

    A manual measurement may be necessary if, for example, the woodpile is too small or if other woodpile requirements (see Chapter B.2) are not met for an sScale™ photo-optic measure- ment. You can also perform a manual measurement for woodpiles that cannot be reached with the vehicle.

  • Page 40: A Measurement Of The Rear Side Of A Woodpile

    TIP: The following table allows you to use the parameters determined by sScale™ to estimate the density of a woodpile relatively precisely, taking into account the parameters that cannot be determined by sScale™.

  • Page 41: Entering Rejects

    The deductions of the blocks 1, 2, 3 and 5 must be estimated by the system user himself and are therefore rather soft parameters. For the additions and deductions of blocks 4, 6 and 7, the quantities issued by sScale™ can be used. 5.2.5. Entering rejects If there are individual logs in the woodpile that are to be marked as reject, you can enter their numbers via button 2.2.7.11 “Reject”.

  • Page 42: Entering Underlays

    With the button 2.2.7.13 “Tree species” you can enter the tree species of the woodpile. A list appears from which you can select the appropriate tree species. The tree species list is cus- tomer-specific and is configured and maintained centrally via the sScale™ server. 5.2.8. Entering the assortment With the button 2.2.7.14 “Assortment”...

    5.3. Functions of the user interface “Edit polygonal course” In addition to optimising the polygonal course (see Chapter 3.2.3), you can also use this user interface to check the log diameter detected by the system and edit it if necessary. 5.3.1.

  • Page 44: Editing A Log Diameter

    5.3.2. Editing a log diameter Log diameters that are too large or too small can be adjusted. To do this, click on the inside of the circle of the respective log. All other diameters will be hidden and the one to be edited will appear in green (see Figure 24).

  • Page 45: Adding And Deleting Log Diameters

    NOTE: Diameters automatically recognised by sScale™ have a very high precision. However, since the monitor has a resolution of about 2 cm/px, the manually changed diameters always have a level of error. This can lead to slight shifts in the representation of the diameter distribution.

  • Page 46: Error Messages

    If, contrary to expectations, a record is damaged during storage or manipulated by third parties despite all the precautions taken by Dralle A/S, this is shown in the user interface 2.2.5 “Details of an archive entry” as shown in Figure 26. The lettering “DATA CORRUPTION!!!” appears...

Requirements for the conformity-rated, indirect photo-optic detection of a woodpile face area Woodpile face shaping: Course as equal-sided trapezoidal shape with an angle α and β between 25 to 89 degrees, a minimum height of 1 m and a minimum width of 2 m to a maximum of 130 m.

To 2) If possible, you can reduce the distance to the woodpile if the total height of the wood- pile is still detected by the cameras and the minimum distance is not less than 1.90 m.

    C. Test Routine 1. Brief description of the system test According to the leaflet “Photo-optical Wood Measurement” of the PTB, the following must be checked when testing a photo-optic measuring system for wood measurement:  Check whether the documentation allows a clear identification of the measuring instru- ment, i.e.

  • Page 52: Necessity Of A System Test

    Detailed notices and instructions for practical implementation can be found in the separate documentation “Checking the Conformity Rating”, which is enclosed with the system. 2. Necessity of a system test Should there be any doubt concerning the measurement results after considerable external influences on the measuring system or the carrier vehicle (for example rear-end collision), the system should be checked.
