How to convert unstructured data to structured data point cloud ?

sara
Hi ,

I have a pcd file , result of 3D reconstruction. It is an unstructured point cloud. I can use structured RGBD point cloud and I know their differences . My Question is about How to do this :
 I wants to convert an unstructured point cloud to structured one , Or in another words who to convert an unstructured point cloud to the RGBD images , Or to a point cloud with structured data ?

My point cloud has 307200 points and it is not result of RGBD . I obtained it with 3D reconstruction and there is not any rule for the place of points in pcd file.

Thanks in advance
Sarah

You can create a range image from point cloud and then convert it to an organized point cloud.

http://docs.pointclouds.org/1.7.0/classpcl_1_1_range_image.html#a82f6a143de2d73a0ad9fea6c527a2efb

I use an interpolation technique.

Can you please explain to me how did you use interpolation technique and how did you make the range image from the cloud ? and did you get a good result ?
thank you so much for the help.
