Detecting a goal is easy. Knowing whether the ball actually crossed the line is a geometry problem. In this #TactiVision R&D module, I combine:
goal keypoint detection to anchor the goal geometry
goal segmentation to estimate the goal area
confidence filtering
geometric projection
polygon-based validation
temporal stabilization The main challenge is robustness: a single weak keypoint near the post can shift the projected goal line, so the system must decide which geometric information can be trusted before confirming a goal. This module is part of my broader football Computer Vision pipeline for detection, tracking, pitch mapping and tactical analysis
