#HKStartups 港大物理系開發AI演算法協助監測光污染，推動市民參與政策制定。研究指出，香港夜空亮度有一半來自建築照明，尤其集中於中環、銅鑼灣等地。新系統讓市民上傳夜間照片，自動辨識光源種類並建立「戶外燈光指數」，提倡採用低藍光照明與評估指標，有望為光污染立法鋪路。
HKU physicists created an AI algorithm to monitor light pollution, inviting citizens to upload night photos for analysis. Their research reveals nearly half of Hong Kong’s night sky brightness stems from decorative lighting, especially in districts like Central and Causeway Bay. The system promotes public engagement in policymaking by building a crowdsourced “Outdoor Lighting Index” and proposing regulation on excessive commercial lighting.
