Detailed Description
PCL-LZF 16-bit depth image format writer.
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.

Save a 16-bit depth image into PCL-LZF format.
- Parameters
-
[in] data the array holding the depth image [in] width the with of the data array [in] height the height of the data array [in] filename the file name to write (preferred extension: .pclzf)
- Returns
- true if operation successful, false otherwise
Implements pcl::io::LZFImageWriter.
writeParameters()
|
overridevirtual |
Write camera parameters to disk.
- Parameters
-
[in] parameters the camera parameters [in] filename the file name to write
- Returns
- true if operation successful, false otherwise This overwrites the following parameters in the xml file, under the <depth> tag: <focal_length_x>...</focal_length_x> <focal_length_y>...</focal_length_y> <principal_point_x>...</principal_point_x> <principal_point_y>...</principal_point_y> <z_multiplication_factor>...</z_multiplication_factor>
Implements pcl::io::LZFImageWriter.
