velo2cam_gazebo /velo2cam_calibration 仿真标定测试

1、下载velocam_gazebo /calibration 项目源码
github网址：
https://github.com/beltransen/velo2cam_gazebo
https://github.com/beltransen/velo2cam_calibration/issues

速度慢或者访问异常，推荐国内gitee、gitcode 镜像；

2、编译平台及要求

ros notic opencv 3.4.15  opencv_contrib(3.4.15) opencv_app
推荐源码编译安装

catkin_ws/src 下编译启用;

3、编译异常处理：

1）、velo2cam_gazebo ：

math::Pose pose; GitHub - beltransen/velo2cam_gazebo: Repository including Gazebo models, plugins and worlds to test calibration algorithms for Lidar-camera setups.中的issues#13，修改为#include <ignition/math/Vector3.hh>

ignition::math::Pose3d pose;和pose.Pos().X()

2）、编译后加载仿真
