利用vs pcl库将多个PCD文件合并成一张PCD地图
主机环境:win10系统,pcl库1.11.1,
vs2019 pcl库安装以及环境配置如下连接:

代码很简单,主要是做个坐标转换,如下:
#include <io.h>
#include <fstream>
#include <string>
#include <vector>
#include <iostream>
#include <iostream> //标准输入输出流
#include <pcl/io/pcd_io.h> //PCL的PCD格式文件的输入输出头文件
#include <pcl/point_types.h> //PCL对各种格式的点的支持头文件
#include <pcl/visualization/pcl_visualizer.h>
#include <pcl/common/transforms.h>
#include <pcl/visualization/cloud_viewer.h>
#include <fstream>
#include <string>
#include <vector>
#include <iostream>
#include <iostream> //标准输入输出流
#include <pcl/io/pcd_io.h> //PCL的PCD格式文件的输入输出头文件
#include <pcl/point_types.h> //PCL对各种格式的点的支持头文件
#include <pcl/visualization/pcl_visualizer.h>
#include <pcl/common/transforms.h>
#include <pcl/visualization/cloud_viewer.h>
