Velodyne Simulator

URDF description and Gazebo plugins to simulate Velodyne laser scanners

rviz screenshot

Features

  • URDF with colored meshes
  • Gazebo plugin based on gazebo_plugins/gazebo_ros_ray_sensor
  • Publishes PointCloud2 with same structure (x, y, z, intensity, ring, time)
  • Simulated Gaussian noise
  • GPU acceleration (with known issues)
  • Supported models:
  • Experimental support for clipping low-intensity returns

Parameters

  • *origin URDF transform from parent link. * parent URDF parent link name. Default base_link
  • name URDF model name. Also used as tf frame_id for PointCloud2 output. Default velodyne * topic PointCloud2 output topic name. Default /velodyne_points
  • hz Update rate in hz. Default 10 * lasers Number of vertical spinning lasers. Default VLP-16: 16, HDL-32E: 32 * samples Nuber of horizontal rotating samples. Default VLP-16: 1875, HDL-32E: 2187 * organize_cloud Organize PointCloud2 into 2D array with NaN placeholders, otherwise 1D array and leave out invlaid points. Default false
  • min_range Minimum range value in meters. Default 0.9 * max_range Maximum range value in meters. Default 130.0
  • noise Gausian noise value in meters. Default 0.008 * min_angle Minimum horizontal angle in radians. Default -3.14
  • max_angle Maximum horizontal angle in radians. Default 3.14 * gpu Use gpu_ray sensor instead of the standard ray sensor. Default false
  • min_intensity The minimum intensity beneath which returns will be clipped. Can be used to remove low-intensity objects.

Known Issues

  • At full sample resolution, Gazebo can take up to 30 seconds to load the VLP-16 pluggin, 60 seconds for the HDL-32E
  • When accelerated with the GPU option, ranges are heavily quantized (image)
    • Solution: Use CPU instead of GPU
  • Gazebo cannot maintain 10Hz with large pointclouds
    • Solution: User can reduce number of points (samples) or frequency (hz) in the urdf parameters, see example.urdf.xacro
  • Gazebo crashes when updating HDL-32E sensors with default number of points. "Took over 1.0 seconds to update a sensor."
    • Solution: User can reduce number of points in urdf (same as above)
