process has died,terminate called after throwing an instance of 'std::runtime_error' ,what(): Unsupported type of detector SURF
After I run:
roslaunch tiago_opencv_tutorial keypoint_tutorial.launch
The error Tips:

Here is my launch File:
<launch> <node name="gui" pkg="tiago_opencv_tutorial" type="gui_find_keypoints.py"/> <node name="vision_code" pkg="tiago_opencv_tutorial" type="find_keypoints" output="screen"/> </launch>
this is unfortunately not an opencv error (and we usually can't help with ROS problems, -- different universe ;(
however, please show your code here (or link us to the tutorial), we cannot do anything without.
then, SURF is usually disabled (nonfree), and you have build the contrib modules using the
-DOPENCV_ENABLE_NONFREE=ONcmake flagopencv version ?
if it's actually this, you could try with another keypoint detector, like "ORB"
