To configure the Human pose detector, do the following:

  1. Go to the Detection Tools tab.
  2. Below the required camera, click Create…  Category: Poses  Human pose detector.

By default, the detection tool is enabled and set to detect poses.

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

ParameterValueDescription
Object features
Record objects trackingYesThe metadata of the video stream is recorded to the database by default. To disable the parameter, select the No value
No
Video streamMain streamIf the camera supports multistreaming, select the stream for which detection is needed. Selecting a low-quality video stream allows reducing the load on the Server
Second stream
Other
EnableYesThe detection tool is enabled by default. To disable the detection tool, select the No value
No
NameHuman pose detectorEnter the detection tool name or leave the default name
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

Number of frames processed per second3

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

Attention!

With static persons in scene, set the FPS to no less than 2. With moving persons in scene, the FPS must be at least 4

The higher the FPS value, the higher the accuracy of pose detection, but the load on the selected processor is higher as well. For FPS=1, the accuracy will be no less than 70%.

This parameter varies depending on the object speed of movement. To solve typical tasks, FPS value from 3 to 20 is sufficient. Examples:

  • pose detection for moderately moving objects (without sudden movements)FPS 3;
  • pose detection for moving objectsFPS 12.

Advanced settings

If detection of small objects or objects in areas far away from the camera is ineffective, you can use the scanning mode (see Configuring the scanning mode). This mode doesn’t provide absolute detection accuracy, but can improve detection performance

Neural network file

Select a neural network file. The standard 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, enter a path to the file.

Note

For the correct neural network operation on Linux OS, place the corresponding file in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory. 

Attention!

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%.

Scanning windowYes The scanning mode is disabled by default. To enable the scanning mode, select the Yes value
No
Scanning window height540

The height and width of the scanning window are determined according to the actual size of the frame and the required number of windows. For example, the real frame size is 1920×1080 pixels. To divide the frame into four equal windows, set the width of the scanning window to 960 pixels and the height to 540 pixels

Scanning window step height540

The scanning step determines the relative offset of the windows. If the step is equal to the height and width of the scanning window respectively, the segments will line up one after another. Reducing the height or width of the scanning step will increase the number of windows due to their overlapping each other with an offset. This will increase the detection accuracy, but will also increase the CPU load

Attention!

The height and width of the scanning step must not be greater than the height and width of the scanning window. The detection tool won't operate with such settings.


Scanning window step width480

The scanning step determines the relative offset of the windows. If the step is equal to the height and width of the scanning window respectively, the segments will line up one after another. Reducing the height or width of the scanning step will increase the number of windows due to their overlapping each other with an offset. This will increase the detection accuracy, but will also increase the CPU load

Attention!

The height and width of the scanning step must not be greater than the height and width of the scanning window. The detection tool won't operate with such settings.

Scanning window width480The height and width of the scanning window are determined according to the actual size of the frame and the required number of windows. For example, the real frame size is 1920×1080 pixels. To divide the frame into four equal windows, set the width of the scanning window to 960 pixels and the height to 540 pixels

ModeCPU

Select the operation mode of the detection tool and neural filter (see Hardware requirements for neural analytics operationSelecting Nvidia GPU when configuring detectors). Neural filter operation mode is used only if you select the Yes value in the Neural filter parameter.

By default, the entire frame is a detection area. In the preview window, you can specify the custom detection areas and skip areas. To specify areas, right-click the frame, and select the required area (see Configuring a skip areaConfiguring a detection area). 

The following logic is used for this:

    1. if you specify only detection areas, no detection will be performed in all other parts of the frame;
    2. if you specify only skip areas, detection will be performed in all other parts of the frame.

Note

  • For convenience of configuration, you can "freeze" the frame. Click the button. To cancel the action, click this button again.
  • The detection area is displayed by default. To hide it, click the button. To cancel the action, click this button again.
  • To delete the selected area, click the button. 

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