Automatic Calculation Program Design of Curve Lofting Based on C + + and Qt

ZHAO Chun-jie;Ningxia Hui Autonomous Region Land Surveying and Mapping Institute;  
The calculation process of curve lofting data based on deflecting angle method is tedious,and the traditional manual method is easily influenced by human factors. When the data is very large,it is easy to make mistakes in the process of calculation and result in making loss in practice. In order to solve the problems mentioned above,an automatic calculation program of curve lofting based on C + + and Qt is proposed in this paper. The program can quickly and accurately realize the automatic calculation of the whole pile mileage number,distance between adjacent pile mileages and deflection angle value in the circular and mitigation curve,which can provide the reliable data for practical lofting. Experiment on the mitigation curve is conducted and the results show that the program can quickly and accurately calculate the lofting data and save the relevant data. The work efficiency can be greatly improved by using the proposed program,and the program can make certain application value.
