The Challenge

Accurately detecting and classifying rust on urban lamp posts is challenging due to variable lighting, shadows, surface dirt, weathering, multiple rust stages, background clutter, and the need for reliable performance in diverse outdoor Hong Kong conditions.

Our Solution

​We created powerful AI software that equips the inspection robot to reliably identify rust, outline affected areas precisely, and assess its severity levels on lamp posts — maintaining strong accuracy despite Hong Kong’s shifting light, rain, haze, dirt buildup, and busy urban surroundings.
