Detailed Description
PCL-LZF 24-bit RGB 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()
| bool pcl::io::LZFRGB24ImageReader::read | ( | const std::string & | filename, |
| pcl::PointCloud< PointT > & | cloud | ||
| ) |
Read the data stored in a PCLZF RGB 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

readOMP()

| pcl::PointCloud< PointT > & | cloud, | ||
| unsigned int | num_threads = 0 |
||
| ) |
Read the data stored in a PCLZF RGB file and convert it to a pcl::PointCloud type.
Note that, unless massively multithreaded, this will likely not result in a significant speedup and may even slow performance.
- 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

readParameters() [1/3]
| bool pcl::io::LZFImageReader::readParameters |
Read camera parameters from a given file and store them internally.
- Returns
- true if operation successful, false otherwise
readParameters() [2/3]
|
inline |
Read camera parameters from a given stream and store them internally.
- Returns
- true if operation successful, false otherwise

readParameters() [3/3]
|
overridevirtual |
Read camera parameters from a given stream and store them internally.
The parameters will be read from the <rgb> ... </rgb> tag.
- Returns
- true if operation successful, false otherwise
