Maximum Value of Feature Extraction

[Nan]

H, I'm just curious about the maximum bounds that stated in in params.yaml. I noticed even if I changed the parameter of min z and max into -10 to 10, the range in the rqt_reconfigure won't be lower or higher than -5 and 5. Since I'm having a high tilted camera, I wish I can adjust the max z into more than 5. Do you have any idea about this? Thanks!
