Image requirements for the Barcode detector and its sub-detectors

Hardware requirements for neural analytics operation

To create the detector, do the following:

  1. Go to the Detection Tools tab.

  2. Below the required camera, click Create… → Category: Retail → Barcode detector.

By default, the 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 of the detector parameters given in the table:

Decoder modeAutoSelect a processing resource for decoding video streams. When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVIDIA NVDEC chips). If there is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding

Neural network file 

If you use a custom neural network, select the corresponding file.

Attention!

  • To train your neural network, contact AxxonSoft (see Data collection requirements for neural network training).
  • A trained neural network for a particular scene allows you to detect only barcode of a certain type.
  • To ensure the correct operation of the neural network on Linux OS, the corresponding file must be located in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory. 
  • If you use 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%. The standard neural networks are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory.
Number of frames processed per second10Specify the number of frames for the detector to process per second. The value must be in the range [0.016, 100]

By default, the entire frame is a detection area. If necessary, in the preview window, set:

To save the parameters of the detector, click the Apply  button. To cancel the changes, click the Cancel  button.

The Barcode Detection is configured.

If necessary, you can search for a barcode in the archive. You can search by the text that was recognized during barcode detection (Search by barcode).
