    Just wow, i'm excited about stitching multiple cloud points which you have mentioned in this video.

    Hello,
    first of all thanks a million for making these videos, they help a lot.
    Question: If you have multiple images of an environment, how do you "stitch all the point clouds together" in order to reconstruct a whole environment?

    • @NicolaiAI

      Hi thank you very much. We are going to cover that in upcoming videos. But u will need to find correspondences in ur point clouds and find the transformations to stitch them together

    How to increase cloud points quality? Need to have better camera with greater image resolution? It depends on how much pixels are out there, right? It will be much more dense, right?

    Hello Neilsen,
    Have you done any research on convertion of point cloud data to RGBD image or (colour and depth image)?
    Or you simply make video on official open3d website content only.
    If you know, please let us know how to convert point cloud to image.

      You reproject a 3d point cloud to an image with opencv
