Welcome to the libE57 website

Welcome to the libE57 reference implementation library of the ASTM E57.4 data interchange standard for 3D laser scanning.

What is it?

The E57 file format specified by the ASTM E57.4 committee provides a compact, vendor-neutral format for storing point clouds, images, and metadata produced by 3D imaging systems, such as laser scanners. The reference library is an implementation of this standard in C++ language, intended to lower the barrier to adoption of the standard and provide a reference to compare other implementations against. It is not expected to be the only implementation and it is not expected to be the fastest implementation that is possible.

Overview

The library provides functionality to create 3D data interchange files and to read from such files. The typical use is for sensor vendors to use the file creation or writer functionality and for software vendors to use the reader part. It is essential to obtain a copy of the standard in order to understand and make full use of the library.

The library is provided in source code form as well as a prebuilt binary for some compilers and operating system platforms. Since the library is written in C++ it is essential to use a binary version that matches your compiler and platform. If there is no version matching your compiler it might be possible to use the source code and compile the library yourself. Instructions for both uses are provided.

The library makes use of some additional libraries that need to be obtained separately:

• boost, a general purpose library

• xerces, a XML library
