Hello, I think I found a bug in the file point_cloud2.py I wrote a python ros node for reading a bag with a pointcloud2 format (and 4 fields, x,y,z,intensity). When I read the 3 first fields, it works fine, but when I read "intensity", i...

A point cloud is a set of data points in 3-D space. The points together represent a 3-D shape or object. Each point in the data set is represented by anx,y, andzgeometric coordinate. Point clouds provide a means of assembling a large number of single spatial measurements into a dataset...
