A discrete point curve modeling algorithm
Zhou We · Automation and Instrumentation · 2010
In science and engineering fields,the movement relationships of some variable between the timeline often need to be studied.Samples data collected need to be interpolated and fitted to draw a smooth continuous curve for the experts to analyze.There are two methods for discrete points modeling and drawing curve.It is fitting and approximating.Fitting over data points,usually using the reverse method obtained corresponding control points,and then B-spline curves.When the data points have many,running speed will be slow.In this paper,a new algorithm is presented to improve computational efficiency of the curve,and solve the discrete point curve modeling problems in engineering application.
