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.
| Number | Interface element | Description |
|---|
| 1 | Workspace | Displays the information about the areas on top of a video image |
| 2 | The High Accuracy Mode |
flag| checkbox | Not used in this version |
| 3 | The Start Time Of |
The | 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 |
| 4 |
Freeway flag| The Freeway checkbox | Enables/disables the freeway mode. |
Should Must be activated for a freeway where the vehicles are moving fast and non-stop |
| 5 | The FailSafe Detection |
ON flag| ON checkbox | Enables/disables the check of the the video signal availability |
check |
| 6 | Number of Zones | Displays the number of zones in the workspace |
| 7 | The Add New |
Zone | Zone button | Adds a new zone to the workspace |
| 8 | The 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 |
| 10 | The 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) |
| 11 | The Directionality drop-down list | Enables/disables the check of the vehicle direction |
check − - —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
|
11| 12 | The Shadow Suppr. drop-down list | Controls the shadow suppression algorithm: |
− - —soft shadow suppression;
- Hard
|
− - —hard shadow suppression;
- Off
|
− - —disables the shadow suppression algorithm
|
12 | WD Check flag | Checking Wrong Direction. Enables/disables the visualization of cases when the vehicle moves in a direction totally opposite to the originally set direction (orange color) |
| 13 | The 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”. |
− 1 Car − 1 Cars − 2 vehicle3 Cars − 3 vehicle Cars − 4 vehicleSuggested Cars | The Suggested Cars Per Zone field | Specifies the estimated number of vehicles that are |
"" | placed in the zone. It is directly associated with the Cars Per Zone parameter |
| 15 |
Sensitivity | The Sensitivity slider | Indicates the sensitivity level of the vehicle detection in the selected |
area| zone |
| 16 | The Work Mode drop-down list | Indicates the operation mode of vehicle detection: |
− - —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
|
| 17 | The Lane ID field | Indicates the identifier of the lane associated with the selected zone. This information is used by the |
IntelliVision | IV vehicle detection module for better detection accuracy |
| 18 | The Auto |
reset time | reset field | Indicates 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) |
| 19 |
Vehicle Counter flag | The 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: - Click the Use STAT Calibration Information button.
- Specify the ABCD rectangle so that it includes the highlighted green zones.
- 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
- 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
