Stitching of point clouds to generate maps.

[qureshinomaan]

If you are a beginner and you want to stitch points cloud to generate maps like the one in the image below, feel free to contact me. It would be a fun experience, and we could learn a lot.

Hey @Thedush, Thanks for your interest!
I think we can proceed in two ways

• Use the camera pose and just append the point clouds together with some downsampling.
• Only use the image data and build the map in a Simultaneous Localisation and mapping fashion.

The first approach is the easier one. I think KITTI Dataset also provides the camera pose along with the test scenes. Let me know what you think.

Hi i am currently working 3d mapping. need to do map stitching automatically. for that i have a multiple pcd files of the map.
now i need a technique automatically correct its orientation and stitch with the main map

Do you have the camera pose for each point cloud?

Hey! I want to stitch the output from two realsense cameras into one single 3D map, any idea/references/code on how to do that?
