Get Started#

  • Time to Complete: 30 minutes

  • Programming Language: Python 3

Prerequisites#

Setup the application#

Note that the following instructions assume Docker engine is setup in the host system.

  1. Clone the edge-ai-suites repository and change into industrial-edge-insights-vision directory. The directory contains the utility scripts required in the instructions that follows.

    git clone https://github.com/open-edge-platform/edge-ai-suites.git
cd edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-vision/

  2. Set app specific environment variable file

    cp .env_worker_safety_gear_detection .env

  3. Edit the HOST_IP and other environment variables in .env file as follows

    HOST_IP=<HOST_IP>   # IP address of server where DLStreamer Pipeline Server is running.

MR_PSQL_PASSWORD=  #PostgreSQL service & client adapter e.g. intel1234

MR_MINIO_ACCESS_KEY=   # MinIO service & client access key e.g. intel1234
MR_MINIO_SECRET_KEY=   # MinIO service & client secret key e.g. intel1234

MR_URL= # Model registry url. Example http://<IP_address_of_model_registry_server>:32002

MTX_WEBRTCICESERVERS2_0_USERNAME=<username>  # WebRTC credentials e.g. intel1234
MTX_WEBRTCICESERVERS2_0_PASSWORD=<password>

# application directory
SAMPLE_APP=worker-safety-gear-detection

  4. Install pre-requisites. Run with sudo if needed.

    ./setup.sh

    This sets up application pre-requisites, download artifacts, sets executable permissions for scripts etc. Downloaded resource directories are made available to the application via volume mounting in docker compose file automatically.

Deploy the Application#

  1. Bring up the application

    docker compose up -d

  2. Fetch the list of pipeline loaded available to launch

    ./sample_list.sh

    This lists the pipeline loaded in DL Streamer Pipeline Server.

    Example Output:

    # Example output for Worker Safety gear detection
Environment variables loaded from [WORKDIR]/manufacturing-ai-suite/industrial-edge-insights-vision/.env
Running sample app: worker-safety-gear-detection
Checking status of dlstreamer-pipeline-server...
Server reachable. HTTP Status Code: 200
Loaded pipelines:
[
    ...
    {
        "description": "DL Streamer Pipeline Server pipeline",
        "name": "user_defined_pipelines",
        "parameters": {
        "properties": {
            "detection-properties": {
                "element": {
                    "format": "element-properties",
                    "name": "detection"
                }
            }
        },
        "type": "object"
        },
        "type": "GStreamer",
        "version": "worker_safety_gear_detection"
    }
    ...
]

  3. Start the sample application with a pipeline.

    ./sample_start.sh -p worker_safety_gear_detection

    This command would look for the payload for the pipeline specified in -p argument above, inside the payload.json file and launch the a pipeline instance in DLStreamer Pipeline Server. Refer to the table, to learn about different options available.

    Output:

    # Example output for Worker Safety gear detection
Environment variables loaded from [WORKDIR]/manufacturing-ai-suite/industrial-edge-insights-vision/.env
Running sample app: worker-safety-gear-detection
Checking status of dlstreamer-pipeline-server...
Server reachable. HTTP Status Code: 200
Loading payload from [WORKDIR]/manufacturing-ai-suite/industrial-edge-insights-vision/apps/worker-safety-gear-detection/payload.json
Payload loaded successfully.

    NOTE: This would start the pipeline. We can view the inference stream on WebRTC by opening a browser and navigating to below url

    http://<HOST_IP>:8889/worker_safety/

  4. Get status of pipeline instance(s) running.

    ./sample_status.sh

    This command lists status of pipeline instances launched during the lifetime of sample application.

    Output:

    # Example output for Worker Safety gear detection
Environment variables loaded from [WORKDIR]/manufacturing-ai-suite/industrial-edge-insights-vision/.env
Running sample app: worker-safety-gear-detection
[
{
    "avg_fps": 30.036955894826452,
    "elapsed_time": 3.096184492111206,
    "id": "784b87b45d1511f08ab0da88aa49c01e",
    "message": "",
    "start_time": 1752100724.3075056,
    "state": "RUNNING"
}
]

  5. Stop pipeline instance.

    ./sample_stop.sh

    This command will stop all instances that are currently in RUNNING state and respond with the last status.

    Output:

    # Example output for Worker Safety gear detection
No pipelines specified. Stopping all pipeline instances
Environment variables loaded from [WORKDIR]/manufacturing-ai-suite/industrial-edge-insights-vision/.env
Running sample app: worker-safety-gear-detection
Checking status of dlstreamer-pipeline-server...
Server reachable. HTTP Status Code: 200
Instance list fetched successfully. HTTP Status Code: 200
Found 1 running pipeline instances.
Stopping pipeline instance with ID: 784b87b45d1511f08ab0da88aa49c01e
Pipeline instance with ID '784b87b45d1511f08ab0da88aa49c01e' stopped successfully. Response: {
    "avg_fps": 29.985911953641363,
    "elapsed_time": 37.45091152191162,
    "id": "784b87b45d1511f08ab0da88aa49c01e",
    "message": "",
    "start_time": 1752100724.3075056,
    "state": "RUNNING"
}

    If you wish to stop a specific instance, you can provide it with an --id argument to the command.
    For example, ./sample_stop.sh --id 784b87b45d1511f08ab0da88aa49c01e

  6. Bring down the application

    docker compose down -v

    This will bring down the services in the application and remove any volumes.
