Video stream and scene requirements for pose Pose detection tooltools

Objects image requirements for pose Pose detection tool

Hardware requirements for neural analytics operation

To configure the common parameters for pose of the Pose detection tools, do as follows:

  1. Select the Pose detection object.
    Image Modified
  2. By default, video stream 's metadata are recorded in to the database. You can disable it by selecting selecting No in the Record objects tracking list (1). Video decompression and analysis are used to obtain metadata, which causes high Server load and limits the number of video cameras that can be used on it.
  3. If a the camera supports multistreaming, select the stream for which detection is needed (2). Selecting a low-quality video stream allows reducing the load on the Server.
  4. Select a processing resource for decoding video streams (3). When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVidia NVIDIA NVDEC chips). If there 's is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding.
  5. Set the frame rate value for the detection tool to process per second (4). This value should be in the range [0.,016, ; 100].

    With static individuals in scene, set the

    FPS to no less than 2. With moving individuals in scene,

    the FPS should be set to 4 and above

    is recommended

    The

    fps

    FPS value, the higher the accuracy of pose detection

    for the cost of CPU load. For fps

    , but the load on the CPU 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

    FPS value from 3 to 20 is sufficient. Examples:

    • pose detection for moderately moving objects (without sudden movements)
    − fps =
    • — FPS 3;
    • pose detection for moving objects
    − fps =
    • — FPS 12.


  6. Select the processor for the neural network − CPU, one of GPUs, or one of Intel NCS GPUs (5, see Hardware requirements for neural analytics operation, General Information on Configuring Detection).

    Note

    If you specify other processing resource than the CPU, the selected device will carry the most of computing load. However, the CPU will also be used to run the detection tool will consume CPU as well.

    It may take several minutes to launch the algorithm on an NVIDIA GPU after you apply the settings.  You You can use caching to speed up future launches (see Configuring the acceleration of GPU-based neuroanalytics).

    Man - down or sitting - pose detection accuracy may depend on the particular processor. If another selected processor gives less accurate results, set the detection parameters empirically, and configure scene perspective (see Specific settings for the Man down detection tool, Specific settings for the Sitting person detection tool).


  7. Select a neural network file (6).

    To ensure the correct operation of the neural network on Linux OS, the corresponding file should be located in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory.


  8. By default, the entire FoV FOV is an area for detection. If necessary, you can specify the areas for detection and skip areas in the preview window. To set an area for detection, right-click anywhere on the image, and select a desired the required area.

    The areas are set the same way as for the Scene Analytics detection tools (see Configuring the Detection Zone).

    This is how it works:

    1. If you specify areas for detection only, no detection will be performed in the rest of FoVFOV.

    2. If you specify skip areas only, the detection will be performed in the rest of FoVFOV.

    Select a neural network file (6).

  10. Set the minimum number of frames with a human in a pose of interest for triggering the toolrelevant pose or behavior for the tool to trigger (8).

    Info
    titleNote

    The default values (2 frames and 1000 milliseconds) indicate that the tool will analyze one frame every second. When a pose is a pose is detected in 2 consequent subsequent frames, the tool will trigger.
