YoloFastestV2 Raspberry Pi 4

YoloFastest V2 with the ncnn framework.

A truly impressive YOLO family member. As long as the images are not too large and/or the objects are too small, very high frame rates are achieved with more than acceptable accuracy. Thanks dog-qiuqiu for all the hard work.

Special adapt for a bare Raspberry Pi 4, see Q-engineering deep learning examples

Dependencies.

To run the application, you have to:

  • A Raspberry Pi 4 with a 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 (Optional). ($ 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/YoloFastestV2-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:
James.mp4
parking.jpg
parking_tiny.jpg
YoloFastestV2.cpb
mainFV2.cpp
yolo-fastestv2.cpp
yolo-fastestv2.h
yolo-fastestv2-opt.bin
yolo-fastestv2-opt.param


Running the app.

To run the application load the project file YoloFastestV2.cbp in Code::Blocks.

Or use Cmake.

$ cd *MyDir*
$ mkdir build
$ cd build
$ cmake ..
$ make -j4

More info or if you want to connect a camera to the app, follow the instructions at Hands-On.

Many thanks to dog-qiuqiu
