Convert geometry_ msgs/Pose to Point

Hey all!,

i got a Posestd::vector<geometry_msgs::Pose> waypoints and now i would like to transform it to geometry_msgs::Point. I tried to convert it to Eigen and afterwards in Point. My first step would be something like:

std::vector<geometry_msgs::Pose> m;
m = waypoints;
Eigen::Affine3d e;
tf::poseMsgToEigen(m,e);

and i get an error: no matching function for call to poseMsgToEigen. Do you have any suggestions ?

Greetings mutu

Hi Mutu,

A geometry_msgs::Pose actually contains a geometry_msgs::Point as you can read in the documentation.

to get the pose just type:

geometry_msgs::Point pt = waypoints[i].position;

for the index i that you want. Do note that you lose the orientation information that is also contained in the pose.
