I'm trying to use the heightmap to detect obstacles, but I cant manage to set the grid_dim to a number higher than 500, and this limits the distance max within which I could detect an obstacle from my point cloud.

The error shown is the following:

[HeightMap-12] process has died [pid 24928, exit code -11, cmd ~/devel/lib/velodyne_height_map/heightmap_node _grid_dimensions:=600 _cell_size:=0.1 _height_threshold:=0.05 __name:=HeightMap __log:= ~/.ros/log/5aa0895e-9ca9-11e9-8d55-ecf4bb5d72d3/HeightMap-12.log]. log file: ~/.ros/log/5aa0895e-9ca9-11e9-8d55-ecf4bb5d72d3/HeightMap-12*.log

Does anyone know if there's a way of setting the parameters with those values?:

  • _grid_dimensions:=1000
  • _cell_size:=0.03
  • _height_threshold:=0.05

Thank you very much!
