Commenting on the challenges of the Land Transport Authority's plan to tap bus cameras to detect traffic offences and structural defects, SMU Professor of Computer Science and Director of CARE.AI Lab Pradeep Varakantham said the proposed solution may face difficulty in differentiating visual clutter – generated from the continuous movement of people and vehicles on the roads – from an offence or defect. He added that bus cameras may not provide a detailed three-dimensional view to recognise offences or defects properly, and additional laser sensors might be needed to provide clearer images.
