not enough correct points

Farahihab opened this issue · comments

I'm using floam with a simulation point cloud sensor which I've recorded in a rosbag.
there seems to be a limitation in the scanned area that is preventing the the map from completing.
I'm not sure what the max_dis parameter in the launch file represents , but I've tried increasing it so that maybe it gives me more space but anything above 110 causes odometry to drift in weird ways.

I've attached a video visualising my problem. point cloud data from rosbag is on the left , floam map is on the right
