Detailed Description

Library for laser scanned data access, compression and analysis.

Implements both common formats, such as LAS and novel algorithms like laserlib::walz.

Todo:

Well, it does not implement very much by now.

Enumeration Type Documentation

enum laserlib::ECompressionType

Compression type.

How to compress the possibly wavelet transformed vectors. Note that you can not combine laserlib::ECT_HUFFMAN with laserlib::EWT_NONE, since Huffman assumes that a wavelet transform has been applied.

Enumerator:

ECT_PACKBITS	=1, Pack bits to a constant length per coordinate, defined by accuracy
ECT_HUFFMAN	=2, Huffman encode

enum laserlib::EFileType

Enumerates laser point file types.

Enumerator:

EFT_UNKNOWN	Unknown file type.
EFT_WALZ	WAvelet Laser Zipper. See laserlib::walz.
EFT_LAS	ASPRS LAS format. Todo: Not implemented.
EFT_XYZ	ASCII XYZ file with arbitary number of entries per point. Todo: Not implemented
EFT_BIN	TerraSolid binary file format. Todo: Not implemented

enum laserlib::EVarType

Type of variable.

Enumerator:

EVT_DOUBLE	Floating point double.
EVT_INT	Integer.
EVT_STRING	String.

enum laserlib::EWaveletType

Wavelet type.

The mother function of the wavelet transform.

Enumerator:

EWT_NONE	=0, Do not do wavelets at all
EWT_DAUB4	=1, DAUB4
EWT_HAAR_UNSYMMETRIC	=2, Haar with forward divided by 0.5 and backward divided by 1.0
EWT_HAAR	=3, Haar with forward and backward divided by sqrt(2.0)
