Challenge
A client from the construction industry needed a dataset for automatic detection of construction equipment on worksites. The goal was to annotate all machinery in the images to enable automated monitoring and tracking of equipment movement.
Key Objectives
- Image Processing: Annotate construction equipment using object detection techniques.
- Dataset Creation: Develop a labeled dataset with equipment classes, including dump trucks, cement mixers, and cranes.

Efficient Annotation
Thanks to a well-prepared workflow, we completed the annotations in just five days. Clear technical guidelines and pre-approved object classes allowed us to streamline the process. The bulk of the annotation work was finished in four days, and when the client provided additional images, our team quickly processed them as well.
In total, we labeled 20,000 bounding boxes for various types of construction equipment across different locations and conditions. Each equipment class was meticulously annotated according to the given specifications.
