To configure the common parameters of the for Pose detection tools, do as follows:
- Select the Pose detection object.
- By default, video stream metadata are recorded to the database. You can disable it by selecting No in the Record objects tracking list (1).
- If 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.
- 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 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.
Set the frame rate value for the detection tool to process per second (4). This value should be in the range [0,016; 100].
Note title Attention! 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.
The higher the FPS value, the higher the accuracy of pose detection, 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 value from 3 to 20 is sufficient. Examples:
- pose detection for moderately moving objects (without sudden movements)
- − FPS 3;
- pose detection for moving objects
- − FPS 12.
Select the processor for the neural network − CPU, one of NVIDIA GPUs , or one of Intel GPUs (5, see see Hardware requirements for neural analytics operation, General Information on Configuring Detection).
Note title Attention! 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.
Note title Attention! It may take several minutes to launch the algorithm on NVIDIA GPU GPU after you apply the settings. You can use caching to speed up future launches (see Configuring the acceleration of GPU-based neuroanalytics).
Note title Attention! 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.
Note title Attention! 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).
Select a neural network file (6).
Info title Note 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.
By default, the entire 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 on the image, and select the required area.
Info title Note The areas are set the same way as for the Scene Analytics detection tools (see Configuring the Detection Zone).
This is how it works:
If if you specify areas for detection only, no detection will be performed in the rest of FOV.
If if you specify skip areas only, the detection will be performed in the rest of FOV.
- Select the required detection tool (7).
Set the minimum number of frames with a relevant pose or behavior for the tool to trigger (8).
Info title Note The default values (2 frames and 1000 milliseconds) indicate that the tool will analyze one frame every second. When a pose is detected in 2 subsequent frames, the tool will trigger.
Info title Note This parameter is not used when configuring people masking.
- Click the Apply button.
