Video stream and scene requirements for the Barcode detector and its sub-detectors

Image requirements for the Barcode detector and its sub-detectors

Hardware requirements for neural analytics operation

To configure the Barcode detectorTo create the detection tool, do the following:

  1. Go to the Detection ToolsDetectors tab.
  2. Below the required camera, click Create…  Category: Retail Barcode Detection detector.

By default, the detection tool detector is enabled and configured for operation. Depending on the required tasks, you must select a specific type of barcode for detection.

If necessary, you can change the settings parameters of the detection tool parameters detector given in the table:

Decode key framesYes

By default, the Decode key frames parameter is enabled. In this case only key frames are decoded. To disable the parameter, select the No value in the corresponding field.
This parameter reduces the load on the Server, but at the same time the detection quality decreases. We recommend enabling this parameter for "blind" (without video image display) Servers on which you want to perform detection.
For the MJPEG codec decoding isn’t relevant, as each frame is considered as a key frame.

Note
titleAttention!

The Number of frames processed per second and Decode key frames parameters are interrelated.

If a local Client isn’t connected to the Server, the following rules work for remote Clients:

  • If the key frame rate is less than the value specified in the Number of frames processed per second field, the detection tool will work by key frames.
  • If the key frame rate is greater than the value specified in the Number of frames processed per second field, the detection will be performed according to the set period.

If a local Client is connected to the Server, the detection tool will always work according to the set period. After disconnecting the local Client, the above rules will be relevant again.

Note
titleAttention!
To ensure the correct operation of the neural network
  • You cannot specify the network file in Windows OS. You must place the neural network file locally, that is, on the same server where you install Axxon One.
  • For correct neural network operation on Linux OS, place the corresponding file
must be located
  • locally in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory
  • or in the network folder with the corresponding access rights.
  • If you use a standard neural network (training wasn't performed in operating conditions), we guarantee the overall accuracy of 80-95% and the percentage of false positives of 5-20%. Standard neural networks are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK folder.
