Description

This task is the subtask of Point cloud feature extraction for LOAM based localization.

• Point cloud feature extraction for LOAM based localization #6741

---

In order to achieve LOAM mapping, firstly we need to project each point cloud into a planar surface. This can be an rangeMat.

Purpose

• Getting projected simultaneous rangeMat to use.

Possible approaches

• Use a matrix to create a projected point cloud rangeMat. The resolution of the matrix can change from point cloud to point cloud.

Definition of done

• Visualize the rangeMat in RViz as a ROS2 topic.
• See the rangeMat in ros2 topic echo ...

Hi guys.

I export a scheme of the imageProjection.cpp of the LIO-SAM. We will work this structure for this issue.

Hi everyone,

I visualized the rangeMat created for feature extraction as an Image topic. Here is the video of it:

You can see the visualization in the below image too.
