为了解决语义目标导航任务中存在的探索效率低、深度不精准等问题,本文构建了一个解决语义目标导航任务的框架,在语义地图构建模块中引入了深度图边缘处理以及地图纠错机制;在探索模块中引入了覆盖范围最大化算法;在路径规划模块中引入了替代点机制.本文在一个 3D仿真环境下进行了实验.实验结果表明,本文提出的解决方案明显提升了语义目标导航任务的性能.此外,本文所提方法成功应用到了四足机器人上,从而验证了其在现实场景下的泛化性.
Object goal navigation based on path planning characteristics
To solve the problems of low exploration efficiency and imprecise depth in object goal navigation,this article constructs a framework to solve object goal navigation.Depth map edge processing and map error correction mechan-isms were introduced in the semantic map construction module;a coverage maximization algorithm was introduced in the exploration module;alternative point mechanisms was introduced in the path planning module.This article conduc-ted experiments in a 3D simulation environment.The experimental results show that the new solution proposed in this article significantly improves the performance of object goal navigation.In addition,the method proposed in this article was successfully applied to quadruped robots,thereby verifying its generalization in real-world scenarios.
