NPU Demo and source code

There are some ready to use NPU demo binaries for VIM3/VIM3L.

This documentation is about how to run these demos on VIM3/VIM3L.

Prepare

You need to run Ubuntu image V20190830 on board, and update the system.

khadas@Khadas:~$ sudo apt-get update
khadas@Khadas:~$ sudo apt-get upgrade
khadas@Khadas:~$ sudo apt-get install -y gstreamer1.0-libav gstreamer1.0-plugins-bad gstreamer1.0-tools gstreamer1.0-plugins-base gstreamer1.0-alsa gstreamer1.0-plugins-good libconfig++9v5 libconfig9
khadas@Khadas:~$ sudo apt-get install -y aml-npu
khadas@Khadas:~$ sudo apt-get install -y gstreamer-aml libplayer-aml opencv3
khadas@Khadas:~$ sync
khadas@Khadas:~$ sudo reboot

Note: You can choose server image to run these demos. If you choose desktop image, you need to switch to the framebuffer console by Ctrl+Alt+F1 to run these demos.

Download NPU demo binaries

khadas@Khadas:~$ sudo -i
root@Khadas:~# git clone https://gitlab.com/khadas/aml_npu_demo_binaries --depth=1

Directory description:

  • detect_demo - Yoloface/YoloV2/YoloV3 demo with video
  • detect_demo_picture - Yoloface/YoloV2/YoloV3 demo with picture
  • inceptionv3 - Inceptionv3

Run Yolo demo with USB camera

Install the libraries:

root@Khadas:~# cd aml_npu_demo_binaries/detect_demo
root@Khadas:~/aml_npu_demo_binaries/detect_demo# ./INSTALL

Run UVC demo:

root@Khadas:~/aml_npu_demo_binaries/detect_demo# ./detect_demo_uvc /dev/videoX 1 > /dev/null

Note: Replace /dev/videoX to the correct node.

You can run ./detect_demo_uvc to get help information and read README to get more information.

Tested USB camera:

  • Logitech C920 PRO
  • Logitech C525

Run Yolo demo with MIPI camera

root@Khadas:~/aml_npu_demo_binaries/detect_demo# ./detect_demo_mipi /dev/videoX  1 > /dev/null

Note: MIPI camera for VIM3 has not launched yet.

In The End

The performance of the video display still need to improve.

Thank you @numbqq . I was looking out for this.
I’ll check it out when I find the time and make a video about it.
Just got the NVIDIA Jetson Nano. So could be nice to do a comparison of both.
The Nano may have a good GPU, but its CPU is mighty slow. Can’t be said about the VIM3.
Greetings.

I got the following error when I run detect_demo in the detect_demo_picture directory:

./detect_demo: error while loading shared libraries: libgtk-3.so.0: cannot open shared object file: No such file or directory

Where can I install libgtk-3.so?

Can you provide this for me? ldd detect_demo ?
