Vertex AI Vision is an AI-powered platform you can use to ingest, analyze, and store video data. Vertex AI Vision lets you build and deploy AI applications. You can build end-to-end Vertex AI Vision solutions by leveraging Vertex AI Vision's integration with other product components.
To start implementing solutions using the Vertex AI Vision platform, review the following Vertex AI Vision concepts and components:
Streams: Represent a video streaming layer from your solution. The stream source can be a live video (for example, an IP camera) or a video file (for example, an MP4 file).
Applications: Enable the connection between a stream and an AI processor to perform a machine learning operation on the video. For example, you can connect a camera stream to an AI model that counts people passing in front of it.
Media warehouses: Store the video ingested by streams out to Google Cloud storage. Storing data out to this destination lets you query analysis output and metadata from the AI processors used on data from the ingested streams.

† Role only needed if you copy a sample video file from a Cloud Storage bucket.
Create an occupancy count application
After you have set up your environment, the first step is to create the app that processes your data. An app can be thought of as an automated pipeline that connects the following:
- Data ingestion: A video feed is ingested into a stream.
- Data analysis: An AI model can be added after the ingestion. Any computer vision operation can be performed on the ingested video information.
- Data storage: The two versions of the video feed (the original stream and the stream processed by the AI model) can be stored in a media warehouse.
In the Google Cloud console an app is represented as a graph. Additionally, in Vertex AI Vision an app graph must have at least two nodes: a video source node (stream), and at least one more node (a processing model or output destination).
Create an empty app
Before you can populate the app graph, you must first create an empty app.
Console
Create an app in the Google Cloud console.
Open the Applications tab of the Vertex AI Vision dashboard.
Click the
Create button.Enter
occupancy-count-app
as the app name and choose your region.Click Create.
Add app component nodes
After you have created the empty application, you can then add the three nodes to the app graph:
- Ingestion node: The stream resource that ingests data sent from a Compute Engine VM instance you create.
- Processing node: The occupancy analytics model that acts on ingested data.
- Storage node: The media warehouse that stores processed videos, and also serves as a metadata store. The warehouse allows analytics information to be generated about ingested video data, as well as stores information that AI models infer about the data.
Console
Add component nodes to your app in the console.
Open the Applications tab of the Vertex AI Vision dashboard.
In the
occupancy-count-app
line, select View graph. This takes you to the graph visualization of the processing pipeline.
Add a data ingestion node
To add an input stream node, select the Streams option in the Connectors section of the side menu.
In the Source section of the Stream menu that opens, select
Add streams.In the Add streams menu, choose
Register new streams and addoccupancy-count-stream
as the stream name.To add the stream to the app graph, click Add streams.
Add a data processing node
To add the occupancy count model node, select the occupancy analytics option in the Specialized models section of the side menu.
Leave the default selections
People and Vehicles.
Add a data storage node
To add the output destination (storage) node, select the Vertex AI Vision's Media Warehouse option in the Connectors section of the side menu.
In the Vertex AI Vision's Media Warehouse menu, click Connect warehouse.
In the Connect warehouse menu, select
Create new warehouse. Name the warehouseoccupancy-count-warehouse
, and leave the TTL duration at 14 days.Click the Create button to add the warehouse.
Deploy your app for use
After you have built your end-to-end app with all the necessary components, the last step to using the app is to deploy it.Console
Open the Applications tab of the Vertex AI Vision dashboard.
Select View graph next to the
occupancy-count-app
app in the list.From the application graph builder page, click the
Deploy button.In the following confirmation dialog, select Deploy.
The deploy operation might take several minutes to complete. After deployment finishes, green check marks appear next to the nodes.
Set up a remote machine to stream video
Now that you have a deployed occupancy count app ready to receive, process, and store streaming data, you must actually stream video data into the app.
In this tutorial you create a Compute Engine VM instance that hosts a video, and you send that streaming video data from the VM.
Create a Linux VM
The first step in sending video from a Compute Engine VM instance is creating the VM instance.
Console
In the console, go to the VM instances page.
Select your project and click Continue.
Click Create instance.
Specify a Name for your VM. For more information, see Resource naming convention.
Optional: Change the Zone for this VM. Compute Engine randomizes the list of zones within each region to encourage use across multiple zones.
Accept the remaining default options. For more information about these options, see Create and start a VM.
To create and start the VM, click Create.
Set up the VM environment
After the VM has started, you can use the console to establish
an SSH
connection in your browser. After establishing this connection, you can download
the vaictl
command-line tool to ingest video into your app.
Console
Establish an SSH connection to your VM
In the console, go to the VM instances page.
In the Connect section of the instance line you created, click SSH. This opens an SSH connection in a new browser window.
Download the vaictl
command-line tool
In the SSH-in-browser window, download the Vertex AI Vision (
vaictl
) command-line tool using the following command:wget https://github.com/google/visionai/releases/download/v0.0.5/visionai_0.0-5_amd64.deb
Install the command-line tool by running the following command:
sudo apt install ./visionai_0.0-5_amd64.deb
You can test the installation by running the following command:
vaictl --help
Ingest a video file into your app
After you set up your VM environment, you can copy a sample video file and then
use vaictl
to stream the video data to your occupancy count app.
SSH-in-browser
Copy a sample video to your VM
- In the SSH-in-browser window for your VM, copy a sample
video with the following
gcloud storage cp
command. Replace the following variable:- SOURCE: The location of a video file to use. You
can use your own video file source (for example,
gs://BUCKET_NAME/FILENAME.mp4
), or use one of the sample videos:
gcloud storage cp SOURCE .
- SOURCE: The location of a video file to use. You
can use your own video file source (for example,
Stream video from VM and ingest data into your app
- To send this local video file to the app input stream, use the
following command. You must make the following variable substitutions:
- PROJECT_ID: Your Google Cloud project ID.
- LOCATION_ID: Your location ID. For example,
us-central1
. For more information, see Cloud locations. - LOCAL_FILE.EXT: The filename of a local video file.
For example,
my-video.mp4
. --loop
flag: Optional. Loops file data to simulate streaming.
This command streams a video file to a stream. If you use the
--loop
flag, the video is looped into the stream until you stop the command:vaictl -p PROJECT_ID \ -l LOCATION_ID \ -c application-cluster-0 \ --service-endpoint visionai.googleapis.com \ send video-file to streams 'occupancy-count-stream' --file-path LOCAL_FILE.EXT --loop
It might take ~100 seconds between starting the vaictl
ingest operation and
the video appearing in the dashboard.
After the stream ingestion is available,
you can see the video feed in the Streams tab of the Vertex AI Vision
dashboard by selecting the occupancy-count-stream
stream.

Search video content in the storage warehouse
After you ingest video data into your processing app, you can view analyzed video data, and search the data based on occupancy analytics information.
Console
Open the Warehouses tab of the Vertex AI Vision dashboard.
Find the
occupancy-count-warehouse
warehouse in the list, and click View assets.In the People count or Vehicle count section, set the Min value to
