Configuring the detection tool

To configure the Equipment detection (PPE)the Equipment detector, do the following:

Go to the Detection Tools tab.
Below the required camera, click Create… → Category: Production Safety → Equipment detection (PPE)detector.

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

Description

Object features

Record mask to archive

Yes

By default, mask is recorded to the archive (human body segmentation) (see Displaying information from a detection tool detector (mask)). To disable the parameter, select the No value

No

Record objects tracking

Yes

The metadata is recorded to the database by default. To disable the parameter, select the No value

No

Video stream

Main stream

If the camera supports multistreaming, select the stream for which detection is needed

Other

Enable

Yes

The detection tool is enabled by default. To disable the detection tool, select the No value

No

Name

Equipment detection (PPE)detector

Enter the detection tool name or leave the default name

Decoder mode

Auto

Select 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

CPU

GPU

HuaweiNPU

Number of frames processed per second

1

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

Note

title	Attention!

To operate the detection in a "gateway" (see Examples of configuring the Equipment detection (PPE) detector for solving typical tasks), we recommend using the standard settings of the detection tool: 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 classification neural network to recognize equipment on each 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.

Info

title	Note

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.

Note

title	Attention!

If you use standard classification 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%.

Сlassification network 2 file

Сlassification network 3 file

Сlassification network 4 file

Сlassification network 5 file

Mask

Yes

The parameter is disabled by default. If you want to display the human body segmentation in the preview window, select the Yes value

No

Number of measurements in a row to trigger detection

3

Specify the minimum number of frames with a violation for the detection tool to generate an event. The value must be in the range [1, 20].

Note

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.

One event per PPE element

Yes

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

Info

title	Example

An individual not wearing a helmet appears in the frame, puts on a helmet, then puts it off. If the One event per PPE element parameter is enabled, you will have one alarm event, otherwise—two.

No

Segmenting network file

By default, the Segmenting neural network is initialized according to the selected processing device in the Neural network mode parameter. The standard segmenting 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.

If you use standard segmenting 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%.

Basic settings

Min person height

0.01

Specify the minimum height and width of a person in the frame as a percentage of the frame height/width (0.15 = 15%). Objects that are smaller than the specified size won't be detected. The value must be in the range [0, 1]

Min person width

0.01

Neural network mode

CPU

Select a processor for the neural network operation (seeHardware requirements for neural analytics operation, Selecting Nvidia GPU when configuring detectors).

Note

title	Attention!

It may take several minutes to launch the algorithm on NVIDIA GPU after you apply the settings. You can use caching to speed up future launches (see Optimizing the operation of neural analytics on GPU in Windows OS, Optimizing the operation of neural analytics on GPU in Linux OS).
If you specify other processing resource than the CPU, this device will carry the most of computing load. However, the CPU will also be used to run the 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.
