The settings file for the IntelliVision IV vehicle detection module is created in the Area editor window.

The description of the Area editor window interface elements is presented in the table below.

NumberInterface elementDescription
1Workspace

Displays the information about the areas on top of a video image

2The High Accuracy Mode
flag
checkboxNot used in this version
3The Start Time Of
The Clip
The field

Not used in this version.

Note. It specifies the start time that will be used as the base for sending the timestamps. The frame timestamp is calculated as the TIME_STAMP = (START_TIME + FRAME_NUMBER * 1 / FPS), where FPS means “Frames per second”, and FRAME_NUMBER is the zero frame index

Freeway flag
The Freeway checkbox

Enables/disables the freeway mode.

Must be activated for a freeway where the vehicles are moving fast and non-stop

6Number of Zones

Displays the number of zones in the workspace

7The Add New

8The Delete Current Zone button

Deletes the current (highlighted in red marks) zone from the workspace

9
Enabled flag
The Enabled checkbox

Enables/disables the processing of the selected zone

10The WD Check checkbox

Checks Wrong Direction. Enables/disables the visualization of cases when the vehicle moves in a direction totally opposite to the originally set direction (orange color)

11The Directionality drop-down list

Enables/disables the check of the vehicle direction

check

:

  • Hard
  • detection of vehicles will be limited to the cars that move in the right direction, or the cars that stopped in the zone;
  • Soft
  • maintains a high level of detection of vehicles that are moving in the wrong direction, but slightly weakens the detection;
  • Off
  • vehicle direction check is disabled

12The Shadow Suppr. drop-down list

Controls the shadow suppression algorithm:

  • Softsoft shadow suppression;
  • Hardhard shadow suppression;
  • Offdisables the shadow suppression algorithm
13The Cars Per Zone drop-down list

Allows specifying the number of vehicles that are

in the zone, if you place them one after another. For detection of stopped cars usually a value of 1 is specified, and the zone of the corresponding size is automatically set, and the entire roadway is filled with these zones. As a result, it becomes possible to create wide, stretched zones that cover the whole or most of the lane compared to when you create several zones of the “single vehicle”.

    14The Suggested Cars
    12Lane Type drop-down list

    It is used to configure the type of detection zone (to configure the response of the algorithm depending on the expected behavior pattern):

    • Left turn − a significant amount of staying (waiting for the green traffic light) traffic is expected;
    • Right Turn − (North America specifics) - minimum vehicle stop time, etc.;
    • Shoulder − not used in this version.

    Note. The Shoulder parameter is used to configure “Roadside” type of detection zones (detection of vehicles that have stopped because of alleged accident)

    13Shadow Suppression drop-down list

    Controls the shadow suppression algorithm:

    • Soft − soft shadow suppression;
    • Hard − hard shadow suppression;
    • Off − disables the shadow suppression algorithm
    14Check Wrong Direction flag

    Enables/disables the visualization of cases when the vehicle moves in a direction totally opposite to the originally set direction (orange color)

    15Suggested Cars

    16Shoulder IsBusy flag

    Not used in this version.

    Note. Enables/disables the display of information and events based on whether the lane of the Roadside type is occupied for more than a certain number of seconds. This type of detection zone is suggested to be installed in the curb area if the analytics are required to detect the cases of roadside occupancy at the installation site of the detection zone by a car, presumably in an emergency

    17Min Busy MSec field

    Not used in this version.

    Note. It is directly associated with the Shoulder IsBusy parameter, and is used to set a time threshold (in seconds) to start sending messages

    16The Work Mode drop-down list

    Indicates the operation mode of vehicle detection:

    • Optimal (default)
    • provides the most balanced and accurate vehicle detection;
    • MinFD
    • provides a good level of vehicle detection, with less false triggerings;
    • MaxTD
    • provides the maximum level of vehicle detection, but sometimes it can produce additional false triggerings

    side length are road dimensions used for more accurate calculation of speed and vehicle class. To do this:

    1. Click the Use STAT Calibration Information button.
    2. Specify the ABCD rectangle so that it includes the highlighted green zones.
    3. Specify the lengths of the sides of the ABCD rectangle in feet: enter the length in the AB and CD fields, enter the width in the BC and DA fields. The diagonal line of the rectangle is calculated and specified automatically in the AC field. The values of these fields are determined empirically and represent the dimensions of the road on which the surveillance camera is installed.
      Image Added
    4. In the Camera field, enter the height of the camera installation in feet, the default value is 23. This value is determined empirically. We recommend installing the camera above the road so that a vehicle going in the outside traffic lane doesn’t block the camera's view of both lanes
