GStreamer - ZED Object Detection Overlay

The ZED Object Detection Overlay, zedodoverlay GStreamer element, is a transform filter that allows drawing object detection bounding boxes on a ZED left color video stream. The incoming data stream must contain ZED Metada/gstreamer, you can use the zeddatamux element to add back metadata to a ZED video stream in case that a GStreamer filter removes them.

The source code of this plugin is a complete example of how to process the ZED metadata in a GStreamer element to retrieve object detection data.

Example pipelines

Display Object Detection bounding boxes

Following a pipeline to acquire a stream at 720p resolution with RGB and MULTI CLASS Object Detection information and display the results on screen:

$
gst-launch-1.0 zedsrc stream-type=0 od-enabled=true od-detection-model=0 camera-resolution=3 camera-fps=30 ! queue ! \
>
zedodoverlay ! queue ! autovideoconvert ! fpsdisplaysink

Display Skeleton Tracking results

The same pipeline of the previous example can be used to display Skeleton TRacking results by simply changing the bt-detection-model property of the zedsrc element

$
gst-launch-1.0 zedsrc stream-type=0 bt-enabled=true bt-detection-model=2 camera-resolution=3 camera-fps=30 ! queue ! \
>
zedodoverlay ! queue ! autovideoconvert ! fpsdisplaysink
