Research development of tire tread wear detection technology

At present, the detection of tire tread wear mainly relies on manual and mechanical measurement, which has low efficiency and poor accuracy, and it is difficult to meet the requirements. Compared with traditional technology, machine vision technology is favored by scholars due to its high efficiency, high precision, and noncontact advantages. Combined with recent progresses of researches at home and abroad, the tire tread wear detection technology is introduced and its future development trend is predicted, which provides reference for future research.
