Automate Marathon Bib Number Recognition with Computer Vision
Blog post from Roboflow
The blog post presents a comprehensive guide on automating marathon bib number recognition using computer vision, aiming to enhance the accuracy and efficiency of runner tracking in races. The proposed solution utilizes Roboflow Workflows, a web-based platform that integrates various computer vision tasks, to detect runners crossing the finish line and accurately record their times. The process is divided into two stages: the first involves setting up an AI workflow to detect runners using object detection models and line counters, while the second focuses on capturing the exact moment and time runners cross the finish line by analyzing video frames and extracting bib numbers with Optical Character Recognition (OCR) tools. The solution not only automates the timing and results generation but also facilitates live tracking, performance analysis, and race photography, significantly reducing human error and manual labor in marathon management.
