Configuring the Stopped vehicle detection program module

You can configure the Stopped vehicle detection program module on the settings panel of the Stopped vehicle detection object that is created on the basis of the Camera object on the Hardware tab of the System settings window.

To configure the Stopped vehicle detection program module, do the following:

1. Go to the settings panel of the Stopped vehicle detection object.
   
2. Click the Settings (1) button. The Detection settings window opens.

3. On the Select area tab (1), set the surveillance zones. You can set several surveillance zones (2). Detector generates a separate event in each surveillance zone.

   Note

   Both the vehicle stop and the stopped vehicle that leaves the boundaries of the zone are detected in each surveillance zone.

   

   To set the surveillance zone, do the following:

   1. Click the Stop video button (3) to capture the frame of the video image.

   2. To add a zone, click the left and right mouse buttons on the frame of the video image.

   3. Set the required size, shape, and position of the surveillance zones:
      • To change the surveillance 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 the dotted-line circle (4).

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

      Note

      Each surveillance zone over its entire area is proportionally covered by detection areas of the specified size. You must 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 with detection areas, use the debug window (see Appendix 1. Debug window).
      • The stopped vehicles can be detected only in those parts of the surveillance zone that are covered with detection areas.
   5. Enter the names of the zones (6).

   6. Select the direction of vehicle movement relative to the camera for the surveillance zone (7).

4. Go to the Parameters tab.
    
5. Set the Traffic jam detection checkbox to receive events about the traffic jams.
6. In the Stop duration (s) field, enter the minimal time of the vehicle stop in seconds.

7. In the Frames processed per second [0.016, 100] field, enter the number of frames that the detector processes per second. The higher the value, the more accurately the detector operates, but the higher the load on the CPU. The default value is 25 frames.

   Note

   You can find all events received from the Stopped vehicle detection object in the Event viewer interface window. For more details, 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 Apply button on the settings panel of the Stopped vehicle detection object.

Configuring the Stopped vehicle detection program module is complete.
