template<typename PointT >
std::string pcl::PCDWriter::generateHeader ( const pcl::PointCloud< PointT > & cloud,
const int nr_points = std::numeric_limits<int>::max ()
)
static

Generate the header of a PCD file format.

Parameters
[in] cloud the point cloud data message
[in] nr_points if given, use this to fill in WIDTH, HEIGHT (=1), and POINTS in the header By default, nr_points is set to INTMAX, and the data in the header is used instead.

setMapSynchronization()

void pcl::PCDWriter::setMapSynchronization ( bool sync )

Note
This option should be used by advanced users only!
Please note that using msync() on certain systems can reduce the I/O performance by up to 80%!
Parameters
[in] sync set to true if msync() should be called before munmap()

write() [1/4]

int pcl::PCDWriter::write ( const std::string & file_name,
const pcl::PCLPointCloud2 & cloud,
const Eigen::Vector4f & origin = Eigen::Vector4f::Zero (),
const Eigen::Quaternionf & orientation = Eigen::Quaternionf::Identity (),
const bool binary = false
)
inlineoverridevirtual

Save point cloud data to a PCD file containing n-D points.

Parameters
[in] file_name the output file name
[in] cloud the point cloud data message
[in] origin the sensor acquisition origin
[in] orientation the sensor acquisition orientation
[in] binary set to true if the file is to be written in a binary PCD format, false (default) for ASCII

Caution: PointCloud structures containing an RGB field have traditionally used packed float values to store RGB data. Storing a float as ASCII can introduce variations to the smallest bits, and thus significantly alter the data. This is a known issue, and the fix involves switching RGB data to be stored as a packed integer in future versions of PCL.

As an intermediary solution, precision 8 is used, which guarantees lossless storage for RGB.

Implements pcl::FileWriter.
