Applications

Face Recognition

FaceView

Advantech FaceView application powered by CyberLink's FaceMe®, an industry-leading facial recognition engine, Advantech’s FaceView application provides precise and scalable real-time facial recognition for various AIoT applications in the retail, hospitality, and public safety fields.

Supported Platforms

• nVidia TX2: EPC-R7000

Installation

0. Before we start for FaceView, please make sure SDK components are installed well on your TX2 device.

1. Get the program file by contact with Advantech, e.g. FaceView_1.0.2.0522_aarch64.run

2. Put the self-extractable file into your device and execute it. Note: Make sure the network is connected!

$ chmod +x FaceView_1.0.2.0522_aarch64.run
$ ./FaceView_1.0.2.0522_aarch64.run

3. Once it's done, you can find the FaceView application in /usr/local/FaceView/ folder.

4. If you want to uninstall FaceView application, use the command below.

$ sudo dpkg --remove FaceView

Setup Camera

We support two kinds of camera on EPC-R7000. One is USB webcam and the other is IP camera.

[USB Webcam]

It's easy to setup webcam by connecting USB with TX2 device.

The two camera products below are verified, but it's OK to use other products which support 1920x1080 or 1280x720 resolution.

• Microsoft LifeCam HD-3000
• Logitech BRIO V-U0040

[IP Camera]

EPC-R7000 supports PoE function, so you can run FaceView with IP camera for more flexible camera configurations.

The IP camera below is verified. We will take it as an example to set up.

• Vivotek_IB9360H

To configure IP camera for FaceView, we have to route RTSP streaming to video device.

1. Connect IP camera with TX2 device via Ethernet cable.

2. Assign corresponding IP address for the PoE port, e.g. 169.254.111.1/16.

3. Install V4L2Loopback utility & drivers.

$ sudo apt-get install v4l2loopback-utils

4. Route RTSP streaming to video device.

$ sudo modprobe v4l2loopback
$ export RTSP_PATH="rtsp://viewer:inventec2017@169.254.6.42:5554/live.sdp"
$ gst-launch-1.0 rtspsrc location="$RTSP_PATH" latency=300 ! rtph264depay ! h264parse ! omxh264dec ! videoconvert ! tee ! v4l2sink device=/dev/video0

Run Application

To execute FaceView application, navigate to /usr/local/FaceView/ folder and double-click FaceView icon, or run the application by command mode.

$ cd /usr/local/FaceView/
$ ./FaceView

Then, you will be asked to input license key. Note: Please make sure your network connection is OK to activate the license successfully.

If the key is valid, you are able to see camera preview screen from the application.

For details of operations, please refer to the FaceView user guide.

Set Up Build Environment

To develop QT application with FaceMe SDK, you have to install the packages listed below.

1. Install FaceMe SDK, e.g.FaceMe_SDK_Ubuntu18_ARM64_3.18.0.run

$ chmod +x FaceMe_SDK_Ubuntu18_ARM64_3.18.0.run
$ ./FaceMe_SDK_Ubuntu18_ARM64_3.18.0.run

Applications Example - Switch Detection Video

This application offers a graphical interface for users to run an object detection demo using either CPU or GPU/NPU to perform inference on a video file.

• Run the Switch Detection Video demo using the following line:

  $ pyeiq --run switch_video

• Type on CPU or GPU/NPU in the terminal to switch between cores.
  • This runs inference on a default video:

Demos Example - Running Object Detection SSD

Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. Well-researched domains of object detection include face detection and pedestrian detection. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance.

• Run the Object Detection Default Image demo using the following line:

  $ pyeiq --run object_detection_tflite

           *  This runs inference on a default image:

• Run the Object Detection Custom Image demo using the following line:

$ pyeiq --run object_detection_tflite --image=/path_to_the_image

• Run the Object Detection Video File using the following line:

$ pyeiq --run object_detection_tflite --video_src=/path_to_the_video

• Run the Object Detection Video Camera or Webcam using the following line:

$ pyeiq --run object_detection_tflite --video_src=/dev/video<index>
