The Study Of The Application Of The Digital Close-range Photogrammetry In3D Reconstruction Of Cultural Relics

Valuable cultural relics are digitized, built network based digital museum system,what can better solve the problem what is the space and time about the exhibits, and further explore the museum protection, research and display a new field, also can realize the museum management ideas and modern management tools. More important is the precise relics digital model recorded relics primitive true3D information and texture information, for the restoration of cultural relics and recovery and provide important data model support. As a result of antiquities, not easy to contact with contour complex, rich texture information and other features, so how to quickly and accurately obtain antiquities DSM became a key point. Digital close-range photogrammetry technology, low cost, small data quantity, processing speed, accuracy and fully meet the demand, therefore, digital close-range photogrammetry in antiquities three-dimensional reconstruction have incomparable advantages.In this paper,through to the general photography measurement software and professional close-up software for exploration and research, the successful realization of the application of close-range photogrammetry software general data fast and high accuracy processing. In this paper, the use of non-metric digital camera and total separated operation method, obtain the antiquarian three-dimensional coordinates, based on the analysis of close-range data pretreatment process, using the optimal calibration algorithm and the calibration reference for accurate calibration of camera, get the camera parameters, then use the general photogrammetry software rapid establishment of artifacts in the DEM, to generate contour lines and ortho image, then solve the problem of image registration, texture mapping and model of seamless splicing, finally will generate a3D model into3DMAX, gave the corresponding materials, thereby realizing the three-dimensional modeling of antiquities. The big wild goose pagoda antiquities group as an example, describes the acquisition of artifacts close-range data the way and the method, and the use of general photogrammetry software PixelGrid for close-range modeling data process. And analysis of the relevant level of precision, as well as the imaging accuracy factors, finally improve the accuracy of the effective suggestion.
