pcd Viewer and visualizer problem RGB Color

This post was updated on .

Hi all,

My current pcl installation is 1.6 on mac osx snow leopard.
i have a problem when display a point cloud with RGB values into pcd viewer or visualizer. The colors are strange and not represent the real color of the point. You will see the problem in a image that i have uploaded. Why this issue? The same point cloud display correctly into a windows machine.
Please help me, thanks.

Hi,

This is a rather known problem. You are using pcd files in ASCII format, right? Try saving as binary and the problems will go away.

Cheers,
Alex

Did you convert the file on the Windows machine? As Alex mentioned, the problem is with Mac OS systems with PCL <= 1.6.
The bug got fixed in trunk and will be released as part of PCL 1.7.

Cheers,
Radu.

I have converted the .pcd ASCII into binary format on mac machine and on windows machine but nothing change.

So i will have to wait the 1.7 release.

But the strange behavior is only at visualization level or it can affect the algorithms logic? (for example calculating the keypoints, features and correspondences)?
