The profiler measures the workpiece to reflect the contour curve shape of the surface of the workpiece. When measuring the same workpiece, the drawn contour curve will shift due to the different placement angle and horizontal position. In order to improve the measurement accuracy of the profiler, the paper proposes a new modelling and calculation method for the profiler. This method uses mathematical methods such as vectors and geometric relations to calculate parameters; then completes level correction by changing the coordinate system; finally, uses geometric methods and analogy inference methods to obtain the deviation between the calculated values of each parameter. The research results show that this method can realize the measurement of the profiler more accurately.
