Design of Image Recognition System Based on FPGA

Hardware Architecture

Hardware Devices

• DE1-SOC board
• Logic C270 UVC camera
• Raspberry Pi 3 B+
• SD Card 16GB+

Software

• Quartus 18.1
• IntelFPGA OpenCL SDK 18.1
• ubuntu 16.04 root file system
• Node.js 11.10.1

How to compile

1. Install Quartus 18.1
2. get this project file:

   git clone https://github.com/YanAndFish/de1-soc_license_plate
   

3. Install DE1-SOC BSP (de1soc_sharedonly_vga) in your Quartus installation directory
4. Open Intel FPGA Embedded Command Shell and make OpenCL file .aocx

   cd ./opencl_host/program
   make fpga
   

   You can find make's files in the Bin folder in the current directory.
5. Copy opencl_host/program in your SD Card Ubuntu file system
6. Copy opencl_host/program/bin/YUYV2RGBHSV/top.rbf in you SD Card boot partition and rename opencl.rbf
7. In DE1-SOC Ubuntu system,open the Terminal to make APP.

   cd opencl_host/program
   make host -j4
   

8. Build Vue. In Raspberry Pi:

   cd web
   npm install
   npm run build
   

How to run

1. In Raspberry Pi, run Python Server:

   cd python
   python3 server.py&
   python3 relay.py&
   

2. In DE1-SOC board,run APP:

   cd opencl_host/program
   ./bin/run
