# Pose estimation and display with LiteRT

Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/single-camera-stream-with-pose-estimation-and-display.html](https://docs.qualcomm.com/doc/80-70018-50/topic/single-camera-stream-with-pose-estimation-and-display.html)

The use cases use the PoseNet LiteRT model to process a single camera stream with
        pose estimation.

## Use qtivoverlay plugin to apply pose estimation overlay

Run the use case:

    gst-launch-1.0 -e \
    qtiqmmfsrc name=camsrc ! video/x-raw,format=NV12_Q08C,width=1280,height=720,framerate=30/1 ! queue ! tee name=split \
    split. ! queue ! qtimetamux name=metamux ! queue ! qtivoverlay ! queue ! waylandsink fullscreen=true sync=false \
    split. ! queue ! qtimlvconverter ! queue ! qtimltflite delegate=external external-delegate-path=libQnnTFLiteDelegate.so \
    external-delegate-options="QNNExternalDelegate,backend_type=htp;" model=/etc/models/hrnet_pose_quantized.tflite ! queue ! \
    qtimlvpose threshold=51.0 results=2 module=hrnet labels=/etc/labels/hrnet_pose.labels \
    constants="hrnet,q-offsets=<8.0>,q-scales=<0.0040499246679246426>;" ! text/x-raw ! queue ! metamux.Copy to clipboard

To stop the use case, use CTRL + C.

The figure shows the flow of the use case execution:

1. Identify poses of people in scenes from a video stream, which is coming through
                    a camera source.
2. Overlay the available poses using overlaylib.
3. Display the results.

The table provides the sequential processing stages of the pipeline execution:

The figure shows the flow of the use case execution:

1. Identify poses of people in the scenes from a video stream, which is coming
                    through a camera source.
2. Compose the poses and video stream using qtivcomposer.
3. Display the results.

The table provides the sequential processing stages of the pipeline execution:
