Why can't the VisonFence recognize elevated obstacles?

VisionFence is not like the human eye with stereo vision, it is a single camera with two-dimensional visual recognition ability. For objects elevated on the ground (e.g., bench chair), the VisionFence may think that they are far away from itself on the surface, and will not trigger obstacle avoidance, so it may hit these objects. For elevated obstacles and larger obstacles, it is recommended to create an off-limit island for higher mowing efficiency and a better experience.
