基于遗传算法的C-Bézier曲线降阶
Degree reduction of C-Bézier curve based on genetic algorithm
摘要
Abstract
Aimingat C-Bezier curve of approximate degree reduction problem, a method for constructing an approximative C-Bezier curve of degree n to a C-Bezier curve of degree n+1 by genetic algorithm is provided. By means of optimization methods, degree reduction of C-Bezier curves is transformed to an optimization problem, by selecting the fitness function, using a simple loop reproduction, copy process, crossover process, mutation process, selection process obtaining the optimal value of the optimization problem to achieve C-Bezier curve endpoints in the endpoint G0 unconstrained and constrained approximate reduction. The experimental results illustrate that the proposed method not only has a good merging effect, but also is easy to implement, has high precision and is simple for error estimation.关键词
