The settings file for the 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 checkboxNot used in this version
3The Start Time Of 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

4The Freeway checkbox

Enables/disables the freeway mode. Must be activated for a freeway where the vehicles are moving fast and non-stop

5The FailSafe Detection ON checkbox

Enables/disables the check of the the video signal availability

6Number of Zones

Displays the number of zones in the workspace

7The Add New Zone buttonAdds a new zone to the workspace
8The Delete Current Zone button

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

9The 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:

  • 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:

  • Soft—soft shadow suppression;
  • Hard—hard shadow suppression;
  • Off—disables the shadow suppression algorithm
13The Cars Per Zone drop-down list

Allows specifying the number of vehicles that are visually 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”.

  • AutoDetect—automatic detection;
  • 1 car—1 vehicle;
  • 2 cars—2 vehicles;
  • 3 cars—3 vehicles;
  • 4 cars—4 vehicles
14The Suggested Cars Per Zone fieldSpecifies the estimated number of vehicles that are visually placed in the zone. It is directly associated with the Cars Per Zone parameter
15The Sensitivity sliderIndicates the sensitivity level of the vehicle detection in the selected zone
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
17The Lane ID fieldIndicates the identifier of the lane associated with the selected zone. This information is used by the IV vehicle detection module for better detection accuracy
18The Auto reset fieldIndicates the time in minutes used to reset the zone if the zone is in the busy state longer than the specified time (default = 0, which means disabled)
19The Use STAT Calibration Information button

Displays/hides a rectangle which values of the 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.

  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
20The Vehicles Counter checkboxEnables/disables the counting of vehicles
21The Speed Measuring checkboxEnables/disables the measuring of vehicles speed
22The Length Measuring checkboxEnables/disables the measuring of vehicles length
23The Debug Window checkboxEnables/disables the debugging mode
24The Show Stats Per Period checkboxEnables/disables display of the statistics once in a time period
25The Save Config buttonSaves the current settings to the settings file in .json format, which then must be specified when configuring the IV vehicle detection object (for details, see Setting up the IV vehicle detection parameters)
26The Load Config buttonLoads the settings file in .json format
27The Run button

It is used to return to the Traffic Monitor window and start monitoring
