No ground plane found in scan

[tomkimsour]

Hello,

I am using ros kinetic and am actually trying to do mapping with octomap but I can't understand properly what this error mean.
It only prompt when i set ground_filter to true.

[pcl::SampleConsensusModelPlane::optimizeModelCoefficients] Not enough inliers found to support a model (0)! Returning the same coefficients.
[ INFO] [1621410313.723860512]: PCL segmentation did not find any plane.
[ WARN] [1621410313.723899495]: No ground plane found in scan

I have no idea where it could be coming from. My odometry seems right, i can map using my lasers.

here is my launch file :

Hi @tomkimsour Did you solve this issue?

Hi @tomkimsour Did you solve this issue?

As far as I remember it was due to the robot lense coefficient but I never solved this problem.

I guess it's because your lidar is 2d lidar rather than 3d lidar.
