How to Launch

1. Add vehicle parameter configuration file to modules/perception/data/params in profile, corresponding frame_id and sensor_name, launch transform

cyber_launch start /apollo/modules/transform/launch/static_transform.launch

2. Modify modules/perception/launch/perception_lidar.launch

• select the dag file to start, add pointcloud_semantic.dag to perception_lidar.launch
• modify msg_adapter. It is used to wrap messages sent by other steps as /apollo/perception/obstacles, this can be used for individual debugging. Modify relevant channel configurations in modules/perception/data/flag/perception_common.flag

3. Modify parameters of modules/perception/pointcloud_semantics/conf/pointcloud_semantic.pb.txt in profile

• output_channel_name: output channel name
• plugin_param: plugin parameters
  • name: method name
  • config_path: configuration folder
  • config_file: configuration file name

4. Launch pointcloud perception

cyber_launch start /apollo/modules/perception/launch/perception_lidar.launch
