Centroid-based robot line following
Loading PDF…
OpenCV locates a colored line centroid for proportional control, with search and obstacle-avoidance states for interrupted tracking.
Main observations
The report documents the image-processing pipeline, control logic and state transitions, accompanied by six original figures.
Scope and limitations
Detection depends on the selected line color. Obstacle avoidance can lose the original line, and the system has no line memory or relocalization.
