License Plate Detection with YOLOv5

In this blog post, we will explore how to implement license plate detection using various techniques such as YOLOv5, MobileNet SSD, and NCNN. We’ll guide you through the installation and execution process to get your detection system up and running!

Understanding the Tools

Before we dive into the setup process, let’s clarify the tools we will be working with:

• YOLOv5: A state-of-the-art, real-time object detection system that is fast and very accurate.
• MobileNet-SSD: A model optimized for mobile devices, which maintains decent accuracy while being lightweight.
• NCNN: A high-performance neural network inference framework designed for mobile applications.

How to Set Up License Plate Detection

Step 1: Clone the Repository

To get started, you’ll need to clone the License Plate Detector repository. Open your terminal or command prompt and execute the following command:

git clone https://github.com/zeusees/License-Plate-Detector.git

Step 2: Install PyTorch

Next, ensure you have PyTorch installed on your machine. It’s recommended to install version 1.7.0 for this project. You can do this using the following command:

pip install torch==1.7.0 torchvision

Make sure you also have Python 3.8 installed on your system.

Step 3: Run the Detection Script

Once the above setups are complete, you can run the license plate detection script with the following command:

python detect_plate.py

Setting Up NCNN for C++ Users

If you prefer working with C++, you can also set up NCNN. Follow these steps:

Step 1: Compile the Source Code

Navigate to the NCNN project directory:

cd Prj-ncnn

Then, run the following commands to compile:

cmake .

make

Troubleshooting

If you encounter any issues during installation or execution, here are some troubleshooting tips:

• Ensure that all dependencies, such as PyTorch, are correctly installed.
• Double-check that the versions of Python and PyTorch are compatible.
• If you face issues running the Python script, make sure your terminal is in the correct directory where the script resides.
• For further clarification and support, consider checking issues on the respective GitHub repositories of the tools mentioned.
