open3d读取、显示和保存点云数据

1、从文件中读取点云

接口1

bool open3d::io::ReadPointCloud	(	const std::string & 	filename,
geometry::PointCloud & 	pointcloud,
const ReadPointCloudOption & 	params = {
   
   } 
)	

接口2

bool open3d::io::ReadPointCloud	(	const std::string & 	filename,
geometry::PointCloud & 	pointcloud,
const std::string & 	file_format,
bool 	remove_nan_points,
bool 	remove_infinite_points,
bool 	print_progress 
)	

接口3

从扩展名中读取点云

bool open3d::io::ReadPointCloudFromPCD	(	const std::string & 	filename,
geometry::PointCloud & 	pointcloud,
const ReadPointCloudOption & 	params 
)	

bool open3d::io::ReadPointCloudFromPLY	(	const std::string & 	filename,
geometry::PointCloud & 	pointcloud,
const ReadPointCloudOption & 	params 

2、保存点云

WritePointCloud()

bool open3d::io::WritePointCloud	(	const std::string & 	filename,
const geometry::PointCloud & 	pointcloud,
const WritePointCloudOption & 	params = {
