technical field [0001] The invention relates to the technical field of automatic drawing of engineering curve groups, in particular to an automatic generation system of engineering curve groups. Background technique [0002] The fields of industrial design, construction and civil engineering, transportation planning and design, and mechanical design all involve a large number of plane curve group drawing work. The efficiency and accuracy of drawing determine the quality of the work results in the above fields, and also greatly affect the implementation effect of the finished project. The requirements for computer-drawn curves in practical engineering include: 1. Calculation and display of basic curve equations - it is required to be able to quickly generate a smooth and unique basic curve line type based on a small number of key points and control conditions provided by the user, and present it with the accuracy required by the user come out. The key lies in: first, the cur...

Problems solved by technology

[0004] (1) The algorithm of encrypting control points based on the principles of linear interpolation and equidistant control does not consider the inhomogeneity of the curvature of the curve enough, resulting in poor accuracy of the curve at places with small curvatures, and encryption redundancy at places with small curvatures. Difficult to balance efficiency and precision;

[0005] (2) Considering only the efficiency of curve drawing, ignoring the reuse of curve equations: in order to improve drawing efficiency, existing methods generate curves with as few control points as possible, and the resulting curve equations are mostly high-order equations

In actual engineering, there are often equation reuse requirements after the curve is generated, such as tracking trajectory as other elements, partial interception of the curve, offset or overall copy of the curve, etc. Operational complexity such as synchronous scaling is high and most of the equations cannot be solved, making it unusable;

[0006] (3) It is limited to solve the drawing problem of a single line, but does not consider the problem of curve offset generation curve group, the calculation and smoothing of connecting lines between curve pairs or between equidistant / unequal offset curve groups, regardless of the line type presentation No practical solution has been given in terms of engineering reuse, and it is difficult to meet the generation and application requirements of curve groups in actual engineering;

[0007] (4) Failure to solve errors such as insufficient precision and deviation of calculation results in the process of computer calculation of curve equations. There is a bottleneck in the realization of algorithm automation, which often leads to fatal errors in computer programming and drawing, and the expected results cannot be achieved.
