Detailed Description

template<typename T>
class sensor_msgs::PointCloud2Iterator< T >

Class that can iterate over a PointCloud2.

T type of the element being iterated upon E.g, you create your PointClou2 message as follows:

  setPointCloud2FieldsByString(cloud_msg, 2, "xyz", "rgb");

For iterating over XYZ, you do :

  sensor_msgs::PointCloud2Iterator<float> iter_x(cloud_msg, "x");

and then access X through iter_x[0] or *iter_x You could create an iterator for Y and Z too but as they are consecutive, you can just use iter_x[1] and iter_x[2]

For iterating over RGB, you do:

sensor_msgs::PointCloud2Iterator<uint8_t> iter_rgb(cloud_msg, "rgb");

and then access R,G,B through iter_rgb[0], iter_rgb[1], iter_rgb[2]
