• custom msg for semantic pointcloud

• fun: fusion pointcloud and semantic img, output semantic pointcloud
• input: raw pointcloud, raw semantic img, calibration matrix, semantic confidence
• output: semantic pointcloud

• fun: based on the input semantic point cloud and localization information, real-time construction of a local semantic 3D voxel map centered around the vehicle, which is then projected into a 2D cost map for subsequent local path planning
• input: fusion semantic pointcloud, location tf
• output: semantic 3D voxel map, 2D costmap

• fun: incorporate DWA (Dynamic Window Approach) for local planning based on the 2D costmap, with DWA introducing semantic costs. The planning process minimizes semantic costs.
• input: 2D costmap, ego status
• output: ego control signals

This project does not provide a model for the semantic segmentation node. You can use any real-time semantic segmentation model of your choice.

1. Only mapping, you can record dataset
2. dataset topics：/raw_img, /raw_lidar, /tf，/semantic_img, /semantic_confidence
3. start fusion node：roslaunch lidar_camera_fusion lidar_camera_fusion_no_msg_sem.launch
4. start mapping node：roslaunch octomap_generator octomap_generator.launch
5. fusion mapping：roalaunch octomap_generator octomap_generator_mapping_scout.launch

• This project does not provide a simulation. I used a vehicle directly at the time.（Agilex Scout）
