VeriLynx

VeriLynx is a built-in FinishLynx profile. This profile is customized to support the use of IdentiLynx cameras for video verification of field events, such as the verification of take-off fouls in the long or triple jump events.

NOTE:  Under World Athletics Technical Rule 30.1.1, horizontal jump take-off failures are re-defined to include any breaking of the vertical plane of the take-off line. Rule 29.5 strongly encourages judges to use video or other technology to assist the decision process. IdentiLynx cameras, along with special configuration of the FinishLynx software, can be used for this purpose.
ClosedHOW TO SELECT THE VERILYNX PROFILE?
  • Using FinishLynx 12.0 or later:

  1. Go to File | Options...

  2. Select VeriLynx from the Profile: list.

  3. Restart FinishLynx.
ClosedHOW TO SETUP VERILYNX HARDWARE?
  • To install IdentiLynx cameras for use with VeriLynx:
  1. Connect IdentiLynx cameras to the FinishLynx PC.
  2. Align one IdentiLynx camera in the plane of the take-off board, making sure the entire width of the board is in the field of view. This camera will be used to judge take-off failures.
  3. (optional) Position a second IdentiLynx camera beyond the take-off board and pointed back toward the runway. This camera will be used for visual confirmation of the current athlete.
TIP: Use Automatic Capture (IdentiLynx Motion) with Active Area limited to the vertical area of the take-off board to make it easy capture all attempts. Set the IdentiLynx camera settings to capture the max frame rate (30+ fps), frame height to high resolution and shutter speed to at least 1/700 for best image quality.
ClosedHOW TO USE VERILYNX FOR FIELD EVENT VIDEO VERIFICATION?
  1. Go to File | Options... | Database and set the Input Directory to the location of the Lynx database files (fldlynx.sch, lynx.evt, lynx.ppl).
  2. Select a new event from the schedule with start list or create a new (blank) event.
  3. Enable capture by clicking the capture icon (Event | Toggle Capture Alt-T).
  4. Use the TAB key to enable the Scroll New Image function.
  5. When an athlete jumps, hit the TAB key to disable Scroll New Image and freeze the view close to the frame showing the attempt.
  6. After each attempt, advance to the image frame showing the attempt, enter the athlete's bib number and hit Enter.

    • This will add a line label, time of day (ToD) timestamp the current frame, export a JPEG and count up the attempt number (starts at 0).

    • To easily go back to any athlete’s recorded jump, select the athlete in the Results Zone (or Shift-ArrowUp/Dn) and go to Results | Previous/Next Attempt (or Shift-ArrowLeft/Right) to cycle through each attempt.

  7. Repeat for all athletes and all attempts in the flight.

ClosedHOW TO AUTOMATICALLY EXPORT A JPEG WHEN I MARK AN ATTEMPT?

Go to File | Options… | Image Export and select On for the Auto-Export feature.

When an attempt is entered, a JPEG file is automatically exported to the Export Directory: on the Database Options tab. By default, this is set to the c:\Lynx folder.

The filename format is <EEE-R-HH>_<ID>_<Attempt#>.jpg.

ClosedHOW TO AVOID CAPTURING IMAGE TRIGGERED BY MOVEMENT IN THE BACKGROUND?

To limit the capture of unwanted image, set the Object Detection’s Active Area to include only the vertical portion of the image that covers the take-off board (Camera Settings > Capture tab).

For details, go to ACM - Active Area.

ClosedHOW TO USE MULTIPLE IDENTILYNX CAMERAS ON THE SAME NETWORK?

To manage multiple IdentiLynx cameras on the same network with multiple PCs, use the FinishLynx camera white list feature.
