Remotely Run Demos on the IEI Tank* AIoT Developer Kit via X2Go*

In this article, we use x2go to connect to a remote system and run a demo, Security Barrier Camera. The demo will be launched on the IEI Tank* AIoT Developer Kit (target) running Linux* from the Developer Workstation (host).

When you run the demo, the command will run on the target from the host and the results will display on the host machine using the x2go client or viewer.

Terminology

Note: VNC server products such as RealVNC  offer enterprise editions and licenses for a fee. 

For this article, the following recommended requirements are listed in the table below.

Requirements

In this article, we will explore using x2go to remotely run the toolkit demo. The host and target in this example are on the same network. 

Security Barrier Camera Demo

The demo you will run is the Security Barrier Camera Demo included in the Intel® Distribution of OpenVINO™ toolkit.  This demo runs multiple deep learning models, including license plate detection, vehicle attributes, and license plate recognition. 

The host system connected to the target system, will be used to run the demo.

Note: The security barrier demo is located at /opt/intel/openvino/deployment_tools/demo

Below is an example of the security barrier demo output.

Step 1: Setup a x2go Connection Between the Target and Host

In this step you will be setting up a connection between your host and target systems. This connection is required. This example scenario includes physical access to the target for setup.

Physical access: Connect a keyboard, monitor, and mouse to your target system.

Install x2go Server

Connect your target system to same network as your host system.

1. On your target system, install x2go server. This is not installed by default. If you do not have add-apt, install software properties.

   sudo apt-get install software-properties-common

2. To add the repo to the sources.list, run the following command:

   sudo add-apt-repository ppa:x2go/stable 

3. Update:

   sudo apt-get update

4. Install the server:

   sudo apt-get install x2goserver x2goserver-xsession

5. Obtain the IP address of the target system (IEI Tank*) using ip or ifconfig:

   ip a

Check the server is running. Run the following command to see if the server is running:

service --status-all | grep x2go

The server is running if your results are:

[ + ] x2goserver

Tip: If your server is not running, start the service:

service x2goserver start

Install x2go client

To install the x2go client on your workstation, run the following command:

sudo apt install x2goclient

Session Preferences

Open the x2go client on the developer workstation.

When you first start x2goclient, session preferences display. Enter the IP address and username (login).

These can be edited in future sessions.

General

You can choose from different desktop environments under Session type. Several Desktop environments are listed in preferences:

• xfce
• lxde
• kde

In this example, we used xfce as the desktop environment. Click OK. The session begins.

Security

There are several options for security.

Note: Without physical access, there are a few ways to discover the IP: Running a port scan, or if you have router access, you can use this to discover the IP address.

Step 2: Run the Security Barrier Camera Demo - CPU

The Security Barrier demo script in the Intel® Distribution of OpenVINO™ toolkit:

• initializes the environment
• downloads the models
• runs the security barrier demo

1. Run this command in the terminal to change to the demo directory. 

   cd /opt/intel/openvino/deployment_tools/demo
   

2. Run the following command to run the demo

    ./demo_security_barrier_camera.sh 
   

The results display with a car being identified in the frame with an overlay of the frames per second.

Because the target device is set at run-time, you can use the same binary to run on CPU, GPU, or other Intel® Vision Accelerator Design product. Run the same demo, but with the GPU to compare performance.
