摘要
曲线测量一直是几何计量中的一个重点。阐述已知曲线和未知曲线测量原理,利用B样条拟合曲线,以及如何借助最小二乘对测量值(二维)进行最佳拟合和偏差处理。
The curve measurement is always the key point of the geometric measurement.The measuring principleo of the known and unknown curves is described in this paper.The principle is using spline B to fit the curve and having the aid of the least square method to do the best fitting and diviation processing.
