In the planner algorithm I use, my robot creates a new path against sudden obstacles according to the lidar data and reaches the target via the new path. But even though the stereo vision camera sees the obstacle, it does not update on the road and continues to go over the obstacle. What might be the cause?

[EDIT]

I am using the Neo Local Planner algorithm on the robot. I use stereo vision camera and Lidar as hardware.

1 . I give the target point with "'2D Nav Goal" from the RVIZ environment to make my robot go to the red dot in picture 1.

2 . In Picture 2, my robot forms its path with the planner and starts its path in that direction.

3 . You can see the obstacles that occur when my robot sees the obstacles created by the point cloud data it receives from the camera in the picture 3-4-5, respectively. However, my robot continues on its way without making any turns against these obstacles and crashes into the obstacle.
