E57 to CGM Conversion
What are E57 files?
E57 is a vendor-neutral file format for data from 3D imaging systems such as laser scanners, standardized as ASTM E2807 by the ASTM E57 committee. A file of this type can hold point clouds, 2D images, and the metadata that describes how they were captured. Its image part stores the photographs taken at each scan station, including panoramic, flat, and cylindrical views, together with the camera type, position, and orientation of every picture. The images are kept as compressed JPEG or PNG blocks, and an optional mask can mark the pixels that contain valid data. A file begins with the ASTM-E57 signature, includes an XML section that describes its structure, and stores the binary data in checked pages. The format is used in surveying, construction, and heritage documentation to exchange scan data between different programs.
What are CGM files?
CGM (Computer Graphics Metafile) is a format that contains vector graphics information (clip art, drawings) associated with graphics design or CAD programs. As opposed to other types of metafiles, such as EMF or WMF, CGM files are not only supported by Windows, but can be used on different platforms too. They are encoded using binary, character-based of clear-text encoding.
