This project is trying to create an efficient computer or machine vision model to detect different kinds of construction equipment in construction sites and we are starting with **three classes which are excavators, trucks, and wheel loaders.**

The **dataset is provided by [Mohamed Sabek](https://www.linkedin.com/in/mohammadsabek/)**, a Spring 2022 Master of Science graduate from Arizona State University in [Construction Management and Technology](https://graduate.engineering.asu.edu/construction-management/).

The raw images (v1) contains:
1. 1,532 annotated examples of "excavators"
2. 1,269 annotated examples of "dump truck"
3. 1,080 annotated examples of "wheel loader"

**Note:** versions 2 and 3 (v2 and v3) contain the raw images resized at 416 by 416 (stretch to) and 640 by 640 (stretch to) without any augmentations.
