Change the orientation of a PointCloud
Hello, I'm trying to change the orientation of a pointcloud topic, I want to change it according to the following equation :
let's say (x,y,z) are the original pointcloud coordinates, and (x',y',z') are the pointcloud cooridnates after the transformation. I want :
x' = -y | y' = -z | z' = x
How can I do that please ?
The transformation you describe is a proper rotation (I.e. not a reflection or distortion of the cloud. The question is why do you need to do this and what format is your point cloud in?
All point cloud types used by ROS describe the frame that the points are represented in. It's possible you just need to update this depending on your application. Can you tell us why you need to rotate the points in this cloud and we can let you know what the best solution will be.
