The AUTO-Uragan, AR-Auto, RR, and VT recognition modules enable estimating vehicle speed by video via the Auto PSIM algorithm. The results are displayed over the video image as captions.

Note

The RR module also allows video speed estimation using a proprietary algorithm. You can configure the speed estimation by video for the RR recognition module on its settings panel (see Configuring the RR software module). If you enable the speed estimation by video on both the settings panel of the LPR channel and on the settings panel of the RR object, then speed is estimated using the Auto PSIM algorithm.

To configure speed estimation by video, do the following:

  1. Go to the settings panel of the LPR channel object, corresponding to the activated module (see Activating the software module used for identifying license plates).
  2. Go to the Advanced settings tab.
  3. Set the Get speed from video checkbox. As a result, settings for speed estimation become available.
  4. Click the Configuration button. The Get speed from video window opens.
    1. Click the  button.
    2. Add a line segment of a known length in centimeters to the video image (1). 
    3. Click the OK button (2).
      The       Get speed from video window closes, and you return to the settings panel of the LPR channel object.
  5. In the Distance field, enter in centimeters the length of the line segment specified in the Get speed from video window.
  6. In the Permitted speed...km/h field, enter the permitted vehicle speed.
  7. In the Alarm on speed limit...km/h field, enter the maximum vehicle speed. If this speed is exceeded, an alarm event is generated.
  8. Set the Use decoder NGP (GPU + CPU) checkbox to enable video decoding using the GPU, reducing the load on the CPU.
  9. Click the Apply button.

Configuring speed estimation by video is completed.
