The invention relates to an online measurement system and method for multiple parameters of a wheel based on structured light. The measurement system comprises a wheel sensor, a first wheel online measurement device and a second wheel online measurement device, and is characterized in that both the first wheel online measurement device and the second wheel online measurement device comprise a tread structured light unit, a profile structured light unit and a two-dimensional image sensor. The tread structured light unit and the profile structured light unit project a profile contour curve and a tread contour curve on the wheel, the two-dimensional image sensor takes images, three-dimensional reconstruction is performed on the images to obtain tread contour information and profile contour information, and the wheel diameter, the wheel flange height and the wheel flange thickness are acquired according to the obtained contour information.
