Configuring PPE detection tool

The PPE detection tool locates people wearing no personal protective equipment within the area where it's required.

For detection tool's operation, you need at least two separate neural networks:

• a segmenting network structures up an image of a human body (locates head, shoulders, arms, hands, thighs, legs and feet);
• a classifying network detects PPE on a specified body part. 

A PPE detection tool may use:

• its own metadata — in this case, the detection tool must be created under a camera parent object;
• metadata from the neural tracker — this requires detection tool creation under the neural tracker object.

To configure the PPE detection tool, do the following:

1. Create a detection tool object under a camera or neural tracker parent object (see Creating Detection Tools).

2. If the camera supports multistreaming, select the stream for which detection is needed (1). 
   

   Note

   If the detection tool is created under a neural tracker, you have to select a video stream from the neural tracker.

3. Set the interval between the analyzed frames - Delay between two measurements -  in milliseconds (2). The value should be within the range of 30 – 10,000.
4. Select the Mask checkbox to display body segments in the preview window (3).
5. Select the processor for the neural network - CPU, one of GPUs, or Intel processors (4, see Hardware requirements for neural analytics operation).
6. Set the minimum number of frames containing people with no PPE for triggering the tool - Number of measurements in a row to trigger detection (5). The value should be within the range of 2 – 20.
7. Select one or several files for the classifying neural network (6). There must be a separate classifying neural network to recognize PPE on each body segment.

8. Select the segmenting neural network file (7).

PPE configuration is now complete. 

The PPE detection tool triggers an alarm when a person not wearing PPE on specified body parts appears in FOV.
