The plane has bumps in elevation_map

Hi, when I did the experiment, I found that there are sharp bumps in the plane,but these bumps should not have existed.I want to know why this happens. sendpix0 I hope you can give me suggestions,Thanks!

Hey @wzy012, usually because of outliers in the input data. Is this from the simulation environment?

Thanks for your apply. It is from real environment.

Ah oki, then this is due to outliers in the sensor reading, which is normal for most depth sensing devices. I recommend looking into elevation map post processors to find a set of filters that remove the outliers.

To confirm, you can check the input point cloud. There you should see that the outlier point exists in the input point cloud.
