The road markings setup should be specified: number and location of the driving lanes and traffic directions.

Note.

Only pre-installed road markings corresponding to the demo video file Demo.avi from the distribution package is always used while working in the demo mode, for example without the RDC Module electronic key (TMKernel). Detailed information about licensing the Traffic Detection module see in the Traffic Detection module licensing section.

To set up the markings parameters, do the following:

  1. Go to the Traffic Detection object settings panel.
  2. Click the Marking setup button and select the Set marking item from the menu (1).
  3. After that, the Advanced settings window opens.
  4. In the Advanced settings window, select the video frame to be used for markings setup.
    To select the frame, click the Select frame button at the appropriate moment.

    The Advanced settings window closes and the Camera Calibration window opens.
  5. Set the switch into the Specify camera parameters position to set camera parameters or into the Specify reference points position to set the keypoints.
    To set camera parameters, do the following:
    1. In the Camera height (m) field enter the height of the camera mounting in meters (1).
    2. In the Focus (mm) field enter the focal distance in millimeters (2).
    3. In the Effective pixels section enter the number of effective pixels in horizontal and vertical direction (3).

    4.  In the Pixel size (um) enter the size of pixel in horizontal and vertical direction (4).

      In case of switch is set into the Specify reference points position:

      Note.

      A keypoint is a small object or a marking easily identified in the image. The actual road markings can be used as key points. No more than two points should lie on a single straight line. The keypoints should be as far from each other as possible, although inside the camera viewing zone. The farther the keypoints are from each other, the more precise will be the setup. Measure and write down the coordinates of actual keypoints on the road relative to any origin. These will be the ground coordinates of the keypoints.

      It is required to specify four keypoints and their coordinates. On default, keypoints are specified automatically.

      To change keypoints and their coordinates do the following:

      1. Remove from the screen the keypoint whose coordinates you want to change. This requires a point with the mouse and hold down the Shift, press the left mouse button.
      2. Click the position for a keypoint in the video frame and press the left mouse button.
      3. In the zoom window that opens, mark the keypoint and enter the ground oordinates in the X and Y fields.

      4. Click OK.

  6. To go to the following step of setting press the Next button.

  7. The Working zone window opens. This window allows setting the road edges, number of lanes and the driving directions.

    By default the road marking is set automatically.
    To set the markings, do the following:

    1. To remove the road edge Shift click one of its endpoints by pressing the left mouse button (1).
    2. To set the road edge, click the road edge in the image, press the left mouse button, drag the cursor to another edge of the road in the video frame, release the button (2).
    3. Set the number of driving lanes (3).
    4. Set the driving direction for each lane (4).
      To go to the following step of setting press the Next button.
  8. The Affixment result window opens.

    The image with the road markings is displayed as the result of the setup.
    To change the width of lane mouse over the internal border of the road markings and expand it to the required size clicking the left mouse button.
  9. Set the Projection checkbox to view the projective image.

    Click the Finish button to complete the setup.
  10. Click Apply (2).

The road markings are now set.
