Well after some thinking, I guess I found an answer to that now. Probably the answer is just a point in the frame of the sensor. I just have polar coordinates then and I have to transform them into cartesian coordinates.
So I think it will be geometry_msgs/PointStamped then, with frame_id sensor_link.
Where x is looking in the direction of the sensors front.
Yes, but actually in the sensors frame it would result in one. Thinking of the sensor as origin. You get an angle for the z axis and a distance to it -> so it is like a polar coordinate you could translate in x and y. Actually I am also not sure if this resolves my problem. Because it is not ...
really a heading I get. It is the ir-sensor from the EV3 which can detect it's infrared beacon. I need to test around with it how this works out. I think it could be used as a source for localization when using two of the beacons. http://www.ev3dev.org/docs/sensors/le... ...
