 Curve fitting is a way of substituting existing data into a mathematical expression through mathematical methods. Scientific and engineering problems can obtain some discrete data through methods such as sampling and experiments. According to these data, we often hope to get a continuous function (that is, a curve) or a more dense discrete equation that matches the known data. This process It's called fitting. In the present invention, the trajectory of the positioning data collected by the positioning terminal is used to perform interpolation calculation through the method of drawing a curve.
 The concept of polynomial interpolation or curve fitting is very broad, as long as the interpolation function is expressed by polynomials, it can be considered as polynomial interpolation. The Bezier curve function can be expressed by polynomi...
