This repo is to detect car parts using the state-of-the-art YOLOv3 computer vision algorithm. For a short write up check out this medium post.
This Project is to detect Five Parts of the car:
- Light(Front and Back Light)
- Glass(Front and Back Glass)
- SideGlass
- Door
- Wheel
Checkout this inputs and outputs,
To build and test your object detection algorithm follow the below steps:
- Image Annotation
- Install Microsoft's Visual Object Tagging Tool (VoTT)
- Annotate images
- Training
- Download pre-trained weights
- Train your custom YOLO model on annotated images
- Inference
- Detect objects in new images and videos

With Google Colab you can skip most of the set up steps and start training your own model right away.
The only hard requirement is a running version of python 3.3 or newer. To install the latest python 3.x version go to
and follow the installation instructions.
To speed up training, it is recommended to use a GPU with CUDA support. For example on AWS you can use a p2.xlarge instance (Tesla K80 GPU with 12GB memory). Inference is very fast even on a CPU with approximately ~2 images per second.
Clone this repo with:
git clone https://github.com/bhadreshpsavani/CarPartsDetectionChallenge
cd CarPartsDetectionChallenge/
Create Virtual (Linux/Mac) Environment (requires venv which is included in the standard library of Python 3.3 or newer):
python3 -m venv env
source env/bin/activate
Make sure that, from now on, you run all commands from within your virtual environment.
Use the Github Desktop GUI to clone this repo to your local machine. Navigate to the CarPartsDetectionChallenge project folder and open a power shell window by pressing Shift + Right Click and selecting Open PowerShell window here in the drop-down menu.
Create Virtual (Windows) Environment (requires venv which is included in the standard library of Python 3.3 or newer):
py -m venv env
.\env\Scripts\activate
Make sure that, from now on, you run all commands from within your virtual environment.
Install all required packages with:
pip install -r requirements.txt
If this fails, you may have to upgrade your pip version first with pip install pip --upgrade. If your system has working CUDA drivers, it will use your GPU automatically for training and inference.
To test the cat face detector on test images located in CarPartsDetectionChallenge/Data/Source_Images/Test_Images run the Minimal_Example.py script in the root folder with:
python Minimal_Example.py
The outputs are saved in CarPartsDetectionChallenge/Data/Source_Images/Test_Image_Detection_Results. This includes:
- Cat pictures with bounding boxes around faces with confidence scores and
Detection_Results.csvfile with file names and locations of bounding boxes.
If you want to detect car parts in your own pictures, replace the cat images in Data/Source_Images/Test_Images with your own images.
To train your own custom YOLO object detector please follow the instructions detailed in the three numbered subfolders of this repo:
To make everything run smoothly it is highly recommended to keep the original folder structure of this repo!
Each *.py script has various command line options that help tweak performance and change things such as input and output directories. All scripts are initialized with good default values that help accomplish all tasks as long as the original folder structure is preserved. To learn more about available command line options of a python script <script_name.py> run:
python <script_name.py> -h
Unless explicitly stated otherwise at the top of a file, all code is licensed under the MIT license. This repo is the fork of TrainYourOwnYOLO which is to train YOLOv3 algorithm cat detection. This repo makes use of ilmonteux/logohunter which itself is inspired by qqwweee/keras-yolo3.
I would like to thank Anton Muelemann for creating TrainYourOwnYOLO repository which really helped me to create this custom object detector.

If you encounter any error, please make sure you follow the instructions exactly (word by word). Once you are familiar with the code, you're welcome to modify it as needed but in order to minimize error, I encourage you to not deviate from the instructions above.
-
If you are using pipenv and are having trouble running
python3 -m venv env, try:pipenv shell -
If you are having trouble getting cv2 to run, try:
apt-get update apt-get install -y libsm6 libxext6 libxrender-dev pip install opencv-python -
If you are a Linux user and having trouble installing
*.snappackage files try:snap install --dangerous vott-2.1.0-linux.snapSee Snap Tutorial for more information.
- [AUG 23, 2021] -> If you have an object detection model, you can now use it with OpenAI's zero shot object tracking repository to do object tracking - no additional modeling required.
- ⭐ star this repo to get notifications on future improvements and
- 🍴 fork this repo if you like to use it as part of your own project.
