Use with PCL? #1

I am currently implementing an ORB-SLAM3 algorithm. I have converted the PointCloud2 message type to a PCL message type. Can this library help to convert the PCL datatype to an OccupancyGrid or any other 2D map using the output from a PointCloud Library?

Hi,

Unfortunately I am not familiar with pointcloud library, is it using a 3-D lidar scan?

Best regards, Aleksa

For us, we used a visual slam system, so it map outs the points of the surrounding and we use pointcloud library to converts it into xyz coordinates, we were wondering if xyz coordinates are enough to be used for grid mapping

Yes, you can create a 3-D grid map from xyz coordinates. But this code itself is just working on 2-D coordinates. You would need to adapt it for 3-D but it is a good starting point.

Good luck, Aleksa
