PROBLEM TO BE SOLVED: To improve reliability of a calculation result in calculation of a correction quantity for curve correction.SOLUTION: A correction quantity calculation system 1 includes an input part 2, a processing part 4, and an output part 4. The processing part 3 includes a design versine calculation part 31 which calculates a design versine of a curve having been corrected based upon a measurement versine, a curve length, and a transition curve length input to an input part 2, and a correction quantity calculation part 32 which calculates a correction quantity at each measurement point from the design versine and measurement versine. The design versine calculation part 31 calculates the design versine so that the design versine has the curve length and transition curve length, the sum in a measurement section is equal to the sum of the measurement versine, and the sum of moment is equal to the sum of moment of the measurement versine. The correction quantity calculation part 32 calculates the correction quantity by using inverse matrix from the design versine and measurement versine. Thus, the correction quantity which corrects the curve length and transition curve length of the design versine into input values can be obtained as a unique solution. |
