Configuring the Stopped vehicle detection module

The Stopped vehicle detection module is configured on the settings panel of the Stopped vehicle detection object, created on the basis of the Camera object on the Hardware tab of the System settings dialog window.

The Stopped vehicle detection module is configured as follows:

1. Go to the settings panel of the Stopped vehicle detection object.
   
2. Click the Settings button. The Detection settings window will open.

3. Set the surveillance zones on the Select area tab (1). Several zones can be added (2). Detection tool triggering in each zone produces a separate event.

   Note

   For each surveillance zone, both vehicle stop and vehicle leaving the zone are detected.

   
   To add a surveillance zone, do the following:

   1. Click the Stop video button (3) to capture the video image.
   2. To add a zone, click any mouse button on the video image.
   3. Set the required size, shape and position of the surveillance zone:
      • to change the zone size, use the anchor points of the zone;
      • to rotate the zone, drag it, while holding the mouse pointer close to the inner perimeter of the zone;
      • to move the zone around the frame of the video image, use a dotted line circle (4).

   4. Specify the approximate size of the vehicle in each surveillance zone by changing the size of the internal areas in the bottom left corner of the zone (5). This field (5) is called the detection area.

      Note

      Each surveillance zone over its entire area is proportionally covered by detection areas of a given size. It is necessary to set the approximate dimensions of the vehicle so that each surveillance zone includes no more than 256 detection areas.

      • To control the coverage of the zone by detection areas, use the debug window (see Appendix 1. Debug window).
      • The stopped cars can be detected only in those parts of the surveillance zone, which are covered with detection areas.
   5. Enter zone name (6).
   6. Select the direction of the vehicles movement relative to the camera for each surveillance zone (7).
4. Go to the Parameters tab (1).
    
5. Set the Traffic jam detection checkbox (2), if you want to receive events about the traffic jams.
6. In the the Stop duration, s field (3), set the vehicle minimal stop duration in seconds.

7. In the Number of processed frames per second (0.016-100) field (4), specify the number of frames the detection tool will process per second. The higher the value, the more accurate the detection tool operates. but the load on the CPU is higher as well. The default value is 25 frames.

   Note

   All events received from the Stopped vehicle detection object can be observed in the Event log interface window (see Operating the Stopped vehicle detection module).

8. Click the OK button to save the changes and return to the settings panel of the Stopped vehicle detection object.
9. Click the Appply button on the settings panel of the Stopped vehicle detection object.

Configuring the Stopped vehicle detection module is completed.
