The Techniques of Cultural Heritage: Literature Review

Documentation of cultural heritage is basically a computerized or digital representation of objects contains the realistic portrayal of objects in 2.5 or 3D and other details. It is an unquestionable reality that the most vital thing for transmitting cultural heritage to posterity is a delicate documentation. Up to the present there have been numerous advancements in documentation of cultural heritage through technology development, and contemporary documentation techniques have progressed speedily. In time, current techniques have turned out to be desirable over conventional methods in engineering in the existent state and in assurance of disfigurements and preparation of measured drawing projects of historical edifices. Over the most recent ten years, direct 3D documentation techniques are very well known and that great advancement. Generally several main geomatics approaches are using for documentation , in first approach, image based such as close range photogrammetry, unmanned aerial vehicles, infrared (IR) images, second approach are non-image-based such as conventional measurements, terrestrial laser scanning, and In third approach, many researcher are using hybrid method that companied between different techniques. With ongoing improvements in PC and information technologies, this notable customary method has been change with digital close-range photogrammetry. This new technique offers us new open doors, for example, automatic orientation and procedure of the measurement, create of 3D vector information, advanced ortho-image and digital surface model. Laser scanning is another innovation that lately has turned out to be progressively well known for documentation which gives exceptionally thick 3D points on an object surface with high exactness. Also, the 3D model and ortho-photo can be effortlessly created utilizing produced 3D point clouds and recorded digital pictures. This paper gives an overview about the techniques related with documentation of cultural heritage and the uses of cultural heritage.
