1， VS2015 PCL1.8.0 相關配置參考 PCL 點雲初識

再根據debug or realse新增 lib

3， 顯示小白兔的程式

#include<pcl/visualization/cloud_viewer.h>
#include<iostream>//標準C++庫中的輸入輸出類相關標頭檔案。
#include<pcl/io/io.h>
#include<pcl/io/pcd_io.h>//pcd 讀寫類相關的標頭檔案。
#include<pcl/io/ply_io.h>
#include<pcl/point_types.h> //PCL中支援的點型別標頭檔案。


using namespace std;
using namespace pcl;



void viewerOneOff(visualization::PCLVisualizer& viewer) {
	viewer.setBackgroundColor(0, 0, 0);   //設定背景顏色為黑色
}

int main() {

	PointCloud<PointXYZ>::Ptr cloud(new PointCloud<PointXYZ>);

	char strfilepath[256] = "rabbit.pcd";
	if (-1 == io::loadPCDFile(strfilepath, *cloud)) {
		cout << "error input!" << endl;
		return -1;
	}

	cout << cloud->points.size() << endl;
	visualization::CloudViewer viewer("Cloud Viewer: Rabbit");     //建立viewer物件

	viewer.showCloud(cloud);
	viewer.runOnVisualizationThreadOnce(viewerOneOff);
	system("pause");
	return 0;
}
 

4, rabbit

5 ，Eigen

#include <iostream>  
#include <Eigen/Dense>  
using namespace Eigen;
int main(int argc, char* argv[])
{
	MatrixXd m(2, 2);
	m(0, 0) = 83;
	m(1, 0) = 10;
	m(0, 1) = -10;
	m(1, 1) = m(1, 0) + m(0, 1);
	std::cout << "Here is the matrix m:\n" << m << std::endl;
	VectorXd v(2);
	v(0) = 4;
	v(1) = v(0) - 1;
	std::cout << "Here is the vector v:\n" << v << std::endl;

	system("pause");
	return 0;
}
