Counting Rebar with Computer Vision

The blog post by Timothy M discusses automating the cumbersome and error-prone task of manual rebar counting using a computer vision model hosted on Roboflow. The proposed system utilizes cameras to capture images of rebar arrangements, which are then analyzed by a pre-existing model from Roboflow Universe without the need for further training, enabling efficient rebar counting for inventory management and quality verification. The application involves using a PHP-based interface where users can upload images, and the Rebar Counting API processes these images to detect and count rebar by drawing bounding boxes around them. The guide provides a detailed walkthrough of setting up the application, including obtaining necessary API credentials, constructing HTTP requests, and processing JSON responses to display results in a user-friendly interface. Additionally, it suggests future enhancements, such as integrating a database for storing batch numbers and counts, to improve the application's utility and analytical capabilities.
