Hi, when reading [the code about calculating 3D points in lidar frame](https://github.com/ankitdhall/lidar_camera_calibration/blob/master/src/find_velodyne_points.cpp#L168), defined in [Corners.cpp](https://github.com/ankitdhall/lidar_camera_calibration/blob/master/src/Corners.cpp), I am confused.The input param **retval** fo function getCorners(), has been transformed into camera frame...

When launch author's aruco_mapping(not the original aruco_mapping) on Ubuntu16.04 + ROS(kinetic), add a Marker in RVIZ, outputs: > [ERROR] [1572071396.201426506]: Client [/rviz] wants topic /aruco_markers to have datatype/md5sum [visualization_msgs/Marker/4048c9de2a16f4ae8e0538085ebf1b97], but...

Hi, everyone! Before publish calculated TF, author changes rotation as follows [Link is here.](https://github.com/laboshinl/loam_velodyne/blob/master/src/lib/LaserOdometry.cpp#L300) > geometry_msgs::Quaternion geoQuat = tf::createQuaternionMsgFromRollPitchYaw(transformSum().rot_z.rad(), -transformSum().rot_x.rad(), -transformSum().rot_y.rad()); _laserOdometryMsg.pose.pose.orientation.x = -geoQuat.y; _laserOdometryMsg.pose.pose.orientation.y = -geoQuat.z; _laserOdometryMsg.pose.pose.orientation.z = geoQuat.x;...

Hi author, After make installed teaser in `/usr/local/`, when using in other project CMakeLists.txt with `find_package(teaserpp REQUIRED)`, it comes out: > CMake Error at hdl_global_localization_noted/CMakeLists.txt:45 (find_package): By not providing "Findteaserpp.cmake"...

lidar_pure_odom_factor

Hi doctor jiao, Thanks for your hard work firsly! I'm curious about the jacobians in `lidar_pure_odom_factor.hpp` and `lidar_online_calib_factor.hpp`, so i carefully calculate them, according to right pertubation of `SO(3)` and...

NDT_CUDA crash

Hi author, I build fast_gicp with `option(BUILD_VGICP_CUDA "Build GPU-powered VGICP" ON)`. Set `reg_method` is `NDT_CUDA_D2D` or `NDT_CUDA_P2D`, hdl will crash when received laser points. But when using with [`FastVGICP_CUDA` and...

Hello author, Dr. @koide3, When we creating predicted measurement sigma points from predicted measurement normal distribution N(mu, sigma), should we add measurement noise covariance into it, in code is [here](https://github.com/koide3/hdl_localization/blob/master/include/kkl/alg/unscented_kalman_filter.hpp#L147)....

can not use hdl_global_localization to init hdl

Hi @koide3, Thanks for your hard wok. I run hdl with `use_global_localization = true, specify_init_pose = false`, then in the terminal `rosservice call /relocalize`, hdl can not be initialized with...

Hi, author, The similar question [issues/44](https://github.com/hyye/lio-mapping/issues/44).  I don't figure out why the code is written like above. It seems that the code in `EstimateGyroBias()` is the approximate expression....
