3D Point Cloud to 2D depth image
显示 更早的评论
Hi
I have a 3D point cloud.
Now I want to convert it to 2D depth image of say 240*320. Does anyone has anything to share?
It will be a good addition to Matlab.
Best Regards Wajahat

X = XYZ(:,1); Y = XYZ(:,2); Z = XYZ(:,3);

Thank u sir for your fast response,
after executing this the final output is point cloud only but while saving that image i am not able to save in .xyz or .ply format (bcoz point cloud should be in .xyz or .ply only) anyway it is saving in .fig format only. but i need to extract x,y,z coornidates for any pointcloud image for further processing like getting surface model for that point cloud data. so please give any solution for my question.

https://www.mathworks.com/help/vision/ref/pcwrite.html writes to ply format.
When you get down to the part of the example that has
% Create the point cloud
ptCloud = pointCloud(points3D, 'Color', color);
then ptCloud.Location will exist.
