A vision-based autonomous UAV inspection framework for unknown tunnel construction sites with dynamic obstacles

1 code implementation20 Jan 2023 Zhefan Xu, Baihan Chen, Xiaoyang Zhan, Yumeng Xiu, Christopher Suzuki, Kenji Shimada

Besides, our framework contains a novel dynamic map module that can simultaneously track dynamic obstacles and represent static obstacles based on an RGB-D camera.

A real-time dynamic obstacle tracking and mapping system for UAV navigation and collision avoidance with an RGB-D camera

1 code implementation17 Sep 2022 Zhefan Xu, Xiaoyang Zhan, Baihan Chen, Yumeng Xiu, Chenhao Yang, Kenji Shimada

Although the popular voxel-based mapping methods can efficiently represent 3D obstacles with arbitrarily complex shapes, they can hardly distinguish between static and dynamic obstacles, leading to the limited performance of obstacle avoidance.

Vision-aided UAV navigation and dynamic obstacle avoidance using gradient-based B-spline trajectory optimization

1 code implementation15 Sep 2022 Zhefan Xu, Yumeng Xiu, Xiaoyang Zhan, Baihan Chen, Kenji Shimada

Although they have shown success in static environments, due to the limitation of map representation, those methods cannot reliably handle static and dynamic obstacles simultaneously.

DPMPC-Planner: A real-time UAV trajectory planning framework for complex static environments with dynamic obstacles

1 code implementation14 Sep 2021 Zhefan Xu, Di Deng, Yiping Dong, Kenji Shimada

Although plenty of recent works achieve safe navigation in complex static environments with sophisticated mapping algorithms, such as occupancy map and ESDF map, these methods cannot reliably handle dynamic environments due to the mapping limitation from moving obstacles.
