The main purpose of the application is to extract traffic data from vehicles on roads using aerial footage taken from static UAVs. To process the footage, deep neural network detector is used (YOLO) alongside with the OpenCV library in ordered to be executed in python. Furthermore, multiple algorithms are used, such as Kalman, Hungarian, in order to match the detections between sequential frames and extract the vehicles and their trajectories. Hence, the velocities and the moving direction of the vehicles are also calculated for each vehicle for every frame.

Steps Covered in this Tutorial
To train our detector we take the following steps:Learn about YOLO
Download and Install YOLOv7 dependencies
Prepare the custom dataset
Run YOLOv7 training
Evaluate YOLOv7 performance
Run YOLOv7 inference on test images / sample video

This repository contains helps indivituals for preparing object detection image data for use in machine learning models. Given a path to a directory containing images and YOLO annotations, the script in this repository can be used to split the data into train, validation, and test sets, and also convert the annotations into VOC and COCO formats, all nice and tidy.
Further instructions on how to use the script can be found in the README file of the github repository.
