从std::vector of 3转换成pcl::PointCloud<PointXYZ>::Ptr？

#include <pcl/point_cloud.h>
#include <pcl/point_types.h>

std::vector<std::array<float, 3>> pointData; // 假设这是包含点坐标数据的std::vector of 3

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

for (const auto& point : pointData) {
    pcl::PointXYZ pclPoint;
    pclPoint.x = point[0];
    pclPoint.y = point[1];
    pclPoint.z = point[2];
    cloud->push_back(pclPoint);
}

#include <pcl/point_cloud.h>
#include <pcl/point_types.h>
#include <array>
#include <vector>

int main() {
    std::vector<std::array<float, 3>> pointData = { {1.0f, 2.0f, 3.0f}, {4.0f, 5.0f, 6.0f}, {7.0f, 8.0f, 9.0f} };

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

    for (const auto& point : pointData) {
        pcl::PointXYZ pclPoint;
        pclPoint.x = point[0];
        pclPoint.y = point[1];
        pclPoint.z = point[2];
        cloud->push_back(pclPoint);
    }

    // 使用转换后的点云数据cloud进行后续操作

    return 0;
