Detailed Description

PCL-LZF 8-bit Bayer image format reader.

The main advantage of using the PCL-LZF image I/O routines is a very good file size versus I/O speed ratio. Tests performed using LZF, Snappy, ZIP, GZ2, BZIP2, as well as PNG, JPEG, and TIFF compression have shown that the internal PCL LZF methods provide the best score for the types of applications PCL is suited for.

Member Function Documentation

◆ read()

template<typename PointT >

bool pcl::io::LZFYUV422ImageReader::read	(	const std::string &	filename,
		pcl::PointCloud< PointT > &	cloud
	)

Read the data stored in a PCLZF YUV422 16bit file and convert it to a pcl::PointCloud type.

Parameters

[in]	filename	the file name to read the data from
[out]	cloud	the resultant output point cloud

Definition at line 312 of file lzf_image_io.hpp.

References pcl::io::LZFImageReader::decompress(), pcl::io::LZFImageReader::getHeight(), pcl::io::LZFImageReader::getImageType(), pcl::io::LZFImageReader::getWidth(), pcl::PointCloud< PointT >::height, pcl::io::LZFImageReader::loadImageBlob(), pcl::PointCloud< PointT >::resize(), and pcl::PointCloud< PointT >::width.

◆ readOMP()

template<typename PointT >

bool pcl::io::LZFYUV422ImageReader::readOMP	(	const std::string &	filename,
		pcl::PointCloud< PointT > &	cloud,
		unsigned int	num_threads = `0`
	)

Read the data stored in a PCLZF YUV422 file and convert it to a pcl::PointCloud type.

Note that, unless massively multithreaded, this will likely not result in a significant speedup

Parameters

[in]	filename	the file name to read the data from
[in]	num_threads	The number of threads to use
[out]	cloud	the resultant output point cloud
