A multi-parameter on-line wheel measurement system based on structured light, which includes a wheel sensor, a first on-line wheel measurement device and a second on-line wheel measurement device, the first on-line wheel measurement device and the second on-line wheel measurement device both include tread structured light Unit, profile structured light unit and two-dimensional image sensor; the tread structured light unit and the profile structured light unit project the profile curve and tread profile curve on the wheel, the two-dimensional image sensor captures the image, and reconstructs the image in three dimensions to obtain the tread and profile Contour information, obtain wheel diameter, rim height and rim thickness according to the obtained contour information; the reliability and measurement accuracy of the present invention are high, and the influence of external ambient light is reduced; two section sections on the same circle can also be used to The diameter of the wheel is obtained by fitting the circle with the contour of the structured light, thus eliminating the need for precise positioning of the wheel. In addition, the invention also discloses a measurement method of the multi-parameter on-line measurement system of the wheel based on structured light. |
