NormalDirectionFilter

NormalDirectionFilter

jsk_pcl/NormalDirectionFilter filters pointcloud based on the direction of the normal. It can filters pointcloud based on static direction and direction based on imu linear_acceleration.

Subscribing Topics

  • ~input (sensor_msgs/PointCloud2)

    input normal pointcloud.

  • ~input_imu (sensor_msgs/Imu)

    imu message, which is enabled if ~use_imu parameter is true

Publishing Topics

  • ~output (pcl_msgs/PointIndices)

    result of filtering as indices. You can use pcl/ExtractIndices to get pointcloud of the indices.

Parameters

  • ~use_imu (Boolean, default: False):

    Enable ~input_imu topic and set target direction based on imu linear acceleration.

  • ~eps_angle (Double, default: 0.2):

    Eps angle difference to regard the normal as required direction.

  • ~angle_offset (Double, default: 0.0):

    Offset parameter to the direction.

  • ~direction (Double Array, required):

    if ~use_imu is false, the direction should be specified with this parmaeter.

  • ~queue_size (Integer, default: 200):

    The length of input queue.
