The present invention discloses a method for evaluating the measurement uncertainties of the speed, distance, and three-dimensional topography of a rotating body. The measurement data of the speed and distance of the rotating body are arranged according to the rotation period, the direction of the rotation axis, and the circumferential direction. The uncertainties of the speed and distance are evaluated according to different rotation periods to eliminate the influence of the speckle effect, the spindle rotation error, and the roundness error of the object, and the uncertainty caused by noise is obtained. The uncertainties of the speed and distance are evaluated along the direction of the rotation axis to eliminate the interference of the spindle rotation error and the roundness error of the object itself on the uncertainty, and the uncertainty component caused by the speckle effect is obtained by combining the uncertainty component caused by noise, and then the total measurement uncertainties of the speed and distance are obtained. Based on the relationship between the surface speed and distance of the rotating body and the three-dimensional absolute topography, the uncertainty components caused by the speckle effect and noise are introduced to obtain the measurement uncertainty of the three-dimensional absolute topography. This method can make a more comprehensive and reasonable evaluation of the measurement uncertainty of the measurement system.
