Hi, I'm trying to the the camera model information by using:
void cameraModel_cb(const sensor_msgs::CameraInfoConstPtr &info_msg) { image_geometry::PinholeCameraModel model_; model_.fromCameraInfo(info_msg); fx = model_.fx(); fy = model_.fy(); }
Where info_msg is /camera/depth_registered/camera_info from the openni.launch node. I need the IR camera focal lenght in order to get range images using:
range_image_.setDepthImage(depthImage,depth_msg->width, depth_msg->height, (depth_msg->width)/2, (depth_msg->height)/2, fx, fy, angular_resolution_);
The problem is that I keep getting this error:
CMakeFiles/keypointsplanar.dir/src/keypointsplanar.o: In function cameraModel_cb(boost::shared_ptr<sensor_msgs::CameraInfo_<std::allocator<void> > const> const&)': /home/jumpei/fuerte_workspace/tesis/src/keypointsplanar.cpp:26: undefined reference to image_geometry::PinholeCameraModel::PinholeCameraModel()'
/home/jumpei/fuerte_workspace/tesis/src/keypointsplanar.cpp:27: undefined reference to `image_geometry::PinholeCameraModel::fromCameraInfo(boost::shared_ptr<sensor_msgs::CameraInfo_std::allocator<void > const> const&)'
collect2: ld returned 1 exit status
when trying to compile my program. I linked the libraries in the CMakeList file like this:
FIND_PACKAGE( OpenCV REQUIRED ) rosbuild_add_executable (keypointsplanar src/keypointsplanar.cpp) TARGET_LINK_LIBRARIES( keypointsplanar ${OpenCV_LIBRARIES} )
I'd really appreciate some help with this problem, thanks in advance.
