In this study, a new method of smooth path planning is proposed based on Bezier curves and is applied to solve the problem of redundant nodes and peak inflection points in the path planning process of traditional algorithms. First, genetic operations are used to obtain the control points of the Bezier curve. Second, a shorter path is selected by an optimization criterion that the length of the Bezier curve is determined by the control points. Finally, a safe distance and adaptive penalty factor are introduced into the fitness function to ensure the safety of the walking process of the robot. Numerous experiments are implemented in two different environments and compared with the existing methods. It is proved that the proposed method is more effective to generate a shorter, smoother, and safer path compared with traditional approaches.
在这项研究中,提出了一种基于 Bezier 曲线的新的平滑路径规划方法,并应用于解决传统算法路径规划过程中冗余节点和峰值拐点的问题。首先,使用遗传操作获得 Bezier 曲线的控制点。其次,通过优化准则选择较短的路径,由控制点确定 Bezier 曲线的长度。最后,将安全距离和自适应惩罚因子引入适应度函数,以确保机器人行走过程的安全。在两个不同的环境中进行了大量实验,并与现有方法进行了比较。实验结果证明,与传统方法相比,该方法能够生成更短、更平滑、更安全的路径。
