Parking Spot Locator

Parking Lot

Python application to detect empty parking lot spots with deep learning from video stream.

  • Keras/TensorFlow deep learning
  • Django user interface
  • OpenCV capture of IP camera

Installation

git clone https://github.com/jmrichardson/vmg.git

conda create -n vmg python=3.6
conda activate vmg
conda install -y -c conda-forge django django-allauth django-crispy-forms 
# Remove "tensorflow-gpu" if you do not have a GPU
conda install -y -c anaconda tensorflow-gpu keras opencv pillow

# Optional LabelImg for Linux (required for generating bounding box coordinates)
sudo apt-get update
sudo apt-get insatll pyqt5-dev-tools
git clone https://github.com/tzutalin/labelImg.git
conda install pyqt=5
conda install lxml
make qt5py3

Annotate Parking Spots

IP camera is assumed to be fixed (no motion/tilt). LabelImg is used to define the parking spot coordinates. Use the following helper script to save a sample image from IP camera to be used in LabelImg.

cd src/parking_spot/data/images
python image.py --labelimg
python3 labelImg.py

After labeling each parking spot with LabelImg, save the resulting XML file:

src/parking_spot/data/images/labelimg/image1.xml

Create Train and Test Image Sets

Save all training and test IP camera images to:

train:  src/parking_spot/data/images/train
test:  src/parking_spot/data/images/test

Use the following helper script to crop each parking spot location from train and test images. This script will use the saved LabelImg xml file to crop each parking spot from the train and test folders.

cd src/parking_spot/data/images
python slice.py --train
python slice.py --test

Each cropped parking spot image will be saved in the following location:

train: src/parking_spot/data/train
test: src/parking_spot/data/test

Manually move each parking spot image to either emtpy or occupied.

Train Model

Train a new deep learning model (be patient ...)

cd src/parking_spot
python model.py

Start Web Application

After model has been trained, start the web application:

cd src
python manage.py runserver
