lunar 基本解释
19. A new method was proposed based on the traversability of obstacle classification aiming at the lunar rover's autonomous navigation in three-dimensional terrain.
针对月球车的三维自主导航，提出了一种新的基于障碍物分类的通行性方法。
20. Path planning is a main task of lunar rover navigation. However, this problem has been mostly neglected within published work. Therefore, this dissertation proposed an intelligent path planning algorithm of lunar rover based on genetic algorithm. This algorithm improved simple genetic algorithm, and present an adaptive genetic algorithm based on knowledge. It used the specialized genetic operators and adjusted adaptively the parameter. In addition, it incorporated the domain knowledge into its initial population. This method increases greatly the efficiency of the algorithm and overcomes the problem of premature convergence of the simple genetic algorithm. This algorithm uses triangulated irregular network to model the virtual environment leading to lower in-core memory consumption. At the same time, there are many factors such as traversability of lunar terrain, systematical uncertainty, assistance of man and smooth of path, which are comprehensively considered. A path cost function is designed in order to safety of the planning path.
路径规划是月球车导航的核心任务，然而，复杂的月面环境下月球车的路径规划问题在已有的工作中却鲜有这方面的研究成果，因此，本文提出了一种基于遗传算法的月球车智能路径规划算法，该算法对传统遗传算法进行了改进，提出了一种基于知识的自适应遗传算法，通过把领域知识并入初始种群及自适应调整控制参数，克服了传统遗传算法的早熟收敛问题，提高了遗传算法的效率；采用三角网格建立虚拟的月表地形环境模型，降低了内存消耗；同时，综合考虑月面地形的可通行性、系统的不确定性、人的辅助性和运动的平滑性等问题，设计路径代价函数，保证了路径规划的安全性。
