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/MobileNetV2_YOLOV3_ncnn/archive/refs/heads/master.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
MobiYO.cpb
MobiYO.cpp
mobilenetv2_yolov3.bin
mobilenetv2_yolov3.param
Running the app.
To run the application load the project file MobiYO.cbp in Code::Blocks. More info or
if you want to connect a camera to the app, follow the instructions at Hands-On.
