autoware_elevation_map_loader
Purpose
This package provides elevation map for autoware_compare_map_segmentation.
Inner-workings / Algorithms
Generate elevation_map from subscribed pointcloud_map and vector_map and publish it. Save the generated elevation_map locally and load it from next time.
The elevation value of each cell is the average value of z of the points of the lowest cluster.
Cells with No elevation value can be inpainted using the values of neighboring cells.
Inputs / Outputs
Input
| Name | Type | Description |
|---|---|---|
input/pointcloud_map |
sensor_msgs::msg::PointCloud2 |
The point cloud map |
input/vector_map |
autoware_map_msgs::msg::LaneletMapBin |
(Optional) The binary data of lanelet2 map |
input/pointcloud_map_metadata |
autoware_map_msgs::msg::PointCloudMapMetaData |
(Optional) The metadata of point cloud map |
Output
| Name | Type | Description |
|---|---|---|
output/elevation_map |
grid_map_msgs::msg::GridMap |
The elevation map |
output/elevation_map_cloud |
sensor_msgs::msg::PointCloud2 |
(Optional) The point cloud generated from the value of elevation map |
Service
| Name | Type | Description |
|---|---|---|
service/get_selected_pcd_map |
autoware_map_msgs::srv::GetSelectedPointCloudMap |
(Optional) service to request point cloud map. If pointcloud_map_loader uses selected pointcloud map loading via ROS 2 service, use this. |
