针对复杂救援环境下无人车(unmanned ground vehicle,UGV)执行任务时由环境未知造成的路径规划问题,提出一种无人机辅助下的救援无人车动态路径规划方法。首先,利用无人机航拍图像,应用加速鲁棒特征(speed up robust features,SURF)算法对航拍图片进行拼接,构建完整地图信息。然后,对图像进行色彩空间转换、形态学处理,识别出障碍信息。最后,应用改进的人工势场法进行无人车路径规划,提出引入动态增益因子与影响函数方法,重新设计了势场函数,解决了目标不可到达问题;同时,提出融合A*算法解决人工势场法局部极小值问题。结果表明,在无突发移动障碍和有突发移动障碍情况下,该无人机辅助下无人车路径规划方法可行且高效,提高了复杂救援环境下无人车路径规划性能。

In view of the problem of path planning caused by unknown environment when unmanned vehicle performs tasks in complex rescue environment, a dynamic path planning method was proposed for unmanned vehicle assisted by UAV. Firstly, UAV aerial images and SURF algorithm were used to assemble the aerial images to build the complete map information.Then the color space conversion and morphological processing were performed to identify the obstacle information.Finally, the improved artificial potential field method was applied to conduct the unmanned vehicle path planning, and the dynamic gain factor and influence function method were proposed to redesign the potential field function to solve the target inaccessible problem; meanwhile, A* algorithm was proposed to solve the local minimum problem of the artificial potential field method. The results show that the UAV-assisted unmanned vehicle path planning method is feasible and efficient, which improves the performance of unmanned vehicle path planning in complex rescue environment.
