目标点总是搜索失败，偶尔有一两次成功。

用rviz的/move_base_simple/goal

Is it possible that the selected point falls within an obstacle? It might be helpful to visualize the costmap to verify the location.

Does it matter if the Z-coordinate is always 0? The target point is not in an obstacle, but in an empty area. Will some isolated noise points in a point cloud map significantly affect the planning algorithm?

May I ask if anyone knows how to solve the problem of the target point always failing to search
