以下是使用PCL库将一个点云旋转45°的示例代码:
```cpp
#include <iostream>
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>
#include <pcl/common/transforms.h>
int main(int argc, char** argv)
{
// 读取点云数据
pcl::PointCloud<pcl::PointXYZ>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZ>);
pcl::PCDReader reader;
reader.read("input_cloud.pcd", *cloud);
// 定义旋转矩阵
Eigen::Matrix4f transform = Eigen::Matrix4f::Identity();
float theta = M_PI / 4; // 旋转角度为45度
transform(0, 0) = cos(theta);
transform(0, 1) = -sin(theta);
transform(1, 0) = sin(theta);
transform(1, 1) = cos(theta);
// 执行点云旋转
pcl::PointCloud<pcl::PointXYZ>::Ptr transformed_cloud(new pcl::PointCloud<pcl::PointXYZ>);
pcl::transformPointCloud(*cloud, *transformed_cloud, transform);
// 保存旋转后的点云数据
pcl::PCDWriter writer;
writer.write("output_cloud.pcd", *transformed_cloud);
return 0;
}
```
注意,上述代码中旋转角度为45度,可以根据需要进行修改。同时,需要将点云数据保存为PCD格式,可以使用PCL中的PCDWriter类进行保存。
