detector

To configure the Equipment detector, do the following:

  1. Go to
  2. the Detection Tools tab
  3. the Detectors tab.
  4. Below the required camera, click click Create…  Category: Production Safety Equipment detector.

By default, the detection tool detector is enabled and set to detect people who enter or stay in the protected area without the necessary equipment and personal protective equipment (PPE).

If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:

will carry will be detection tool.If you select Intel HDDL, due to the features of the device, only the segmenting neural network will be processed on it, the CPU will be used to run the classification neural networks.

Number of frames processed per second1

Specify the number of frames that the detection tool detector will process per second. The value must be in the range [0.016; , 100].

Note
titleAttention!

To operate the detection detector in a "gateway" (see Examples of configuring the Equipment detector for solving typical tasks), we recommend using the standard settings of the detection tooldetector: 1 FPS and 3 FPS for output.

In conditions of dynamically moving people, we recommend setting the delay to at least 4 FPS, and the number of frames for output to at least 6 FPS.

Advanced settings
Сlassification network 1 file

By default, the following neural networks are initialized: Classification neural network (equipment and PPE on the head) and Classification neural network (equipment and PPE on the body) according to the selected processing device in the Neural network mode parameter. To initialize only one item of equipment, select the required classification neural network file
There must be a separate Each classification neural network to recognize recognizes equipment on each the specific body segment. The standard classification neural networks for different processor types are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory.   You don't need to select the standard neural networks in this field, the system will automatically select the required one. If you use a custom neural network, specify the path to the file.

One event per PPE elementYes

By default, the detection tool detector's event is generated once for each element of equipment within a track of a person. If you want the detection tool detector to generate an event for each equipment violation, select the No value.

  1. Detection in gateway conditions. A gateway is a border, which can either be a virtual line or a door, a barrier, a turnstile. The algorithm for working in gateway conditions is as followsthe following:
    1. A person stops in front of an area where equipment or PPE is required.
    2. A person poses in a way that it is possible to check the presence of all elements of equipment (the element must not be overlapped by the person, other elements of equipment, or items of clothing).
    3. Screening of a person. There must be no obstacles between the person and the camera, blocking the person for screening.
  2. Detection in a production conditions: persons move freely in the detection area.
