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?
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.
Hi, I tried your algorithm with my ToF camera rgbd image, but it didn't show me point cloud instead it open white screen. Can you describe what can be a problem here?
@@NicolaiAI thank you for your answer :) i am new on your channel is there a video or github link with code for such a transformation. I need a solution for my thesis as this step is only a small part of the whole work.

Just wow, i'm excited about stitching multiple cloud points which you have mentioned in this video.
Hey! Did you try Nerf(Nvidia Instant-NGP) + Open 3D? Coul be a great tutorial :)

@@NicolaiAI Hi have you released a video for that yet?

You reproject a 3d point cloud to an image with opencv
@@NicolaiAI I tried that but it is taking only x,y coordinates into account. Do you know any other method or open3d funtion for that? Thank you
@@NicolaiAI Hi Nicolai, do you know how to convert the 3d point cloud to range image instead?
I'm working on something similar. Have you made any progress yet?
Can you provide the notebooks that you used in these videos? I cannot find them in the repo. Thanks :)
Is the Jupyter notebook available for download somewhere?
Should be available on my GitHub
So with this method if we have a depthmap ( grayscale 2d depthmap from kinect) we can get a cloudpoint? ???
Yeah that's correct
@@NicolaiAI Thx for the quick answer and interesting video = I subscribed to your chan
@@nobodyelse-h6h thanks for watching!
Where can i acquire the jupyter nootbook files use in the course?
Thnanks for the nice video! How can I generate one whole indoor room reconstruction? Like 360 degree indoor room
Thanks for your video! I want to ask a question about how can I transform jpg or png files to 3d model with color?
我也想知道如何把颜色信息加入到模型中去
did u find how plz reply me ????????????????
Outstanding!!!
Thanks a lot! Really appreciate it

is it possible to classify objects using point clouds that are created from Depth maps
How do you get all the sample data in the first place? I tried to find where to download it and no luck :(
Hey,
great video is there a way to bring a point cloud array to 2d Image oder a depth map. Im asking for a object detection with with point cloud data
Thank you so much! u can just project the 3d points down on the image plane again and do it in that way
@@NicolaiAI thank you for your answer :) i am new on your channel is there a video or github link with code for such a transformation. I need a solution for my thesis as this step is only a small part of the whole work.
@@NicolaiAI please how do you do the projection, both from 3d to 2d and vise versa
@@moseschuka7572 I have videos about that on my channel in the computer vision playlist
Thank you, how do we do it with multiple images and deapths?
We are going to do that in future videos!
Hi, How do you access the pages you show in your video?
the videos is great ! ! !😁
Thank you very much! Really appreciate it
Hey can we export point cloud into fbx file format
will you do 3d Segmentation ?
I have that covered very shortly in one of the videos. But there will definitely be more videos about it in the near future
i am not able to use open3D without GPU 😢
