【摘要】 提出了一种应用于非开挖管线测量,在已知离散点曲率的情况下进行空间曲线重构的方法。运用了差分和数值积分的方法重构了被测管线的轴线,并给出了一种修正方法,进一步提高了积分精度。文中给出的算例说明了本算法是可行的,并具有比较高的精度。更多还原

【Abstract】 A reconstruction method of using the discrete curvature data for space curve was proposed on underground pipeline detection.The difference method and numerical integration were used to reconstruct the axes of the underground pipelines,and an amendatory solution was provided to increase the integral precision.The given numerical example demonstrates that the algorithm is feasible and comparatively precise.更多还原
