¹ The Rock 5 and Orange Pi5 have the RK3588 on board.
² The Rock 3, Radxa Zero 3 and Orange Pi3B have the RK3566 on board.
²⁰ Recognize 20 objects (VOC) instead of 80 (COCO)

Dependencies.

To run the application, you have to:

• A Raspberry Pi 4 with a 32 or 64-bit operating system. It can be the Raspberry 64-bit OS, or Ubuntu 18.04 / 20.04. Install 64-bit OS
  
• The Tencent ncnn framework installed. Install ncnn
  
• OpenCV 64-bit installed. Install OpenCV 4.5
  
• Code::Blocks installed. ($ sudo apt-get install codeblocks)

---

Installing the app.

To extract and run the network in Code::Blocks
$ mkdir MyDir
$ cd MyDir
$ wget https://github.com/Qengineering/YoloV8-ncnn-Raspberry-Pi-4/archive/refs/heads/main.zip
$ unzip -j master.zip
Remove master.zip, LICENSE and README.md as they are no longer needed.
$ rm master.zip
$ rm LICENSE
$ rm README.md

Your MyDir folder must now look like this:
parking.jpg
busstop.jpg
YoloV8.cpb
yoloV8main.cpp
yoloV8.cpp
yoloV8.h
yolov8s.bin
yolov8s.param
yolov8n.bin
yolov8n.param

---

Running the app.

To run the application load the project file YoloV8.cbp in Code::Blocks. More info or
if you want to connect a camera to the app, follow the instructions at Hands-On.

Thanks.

A more than special thanks to FeiGeChuanShu, who adapted the YoloV8 model to the ncnn framework.
