Embodiment Construction

[0041] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0042] See figure 1 As shown, a method for generating a cultural heritage three-dimensional scene is characterized in that it comprises the following steps:

[0043] Step 1, cultural heritage remote sensing data preparation step, to obtain geographic information data in the cultural heritage area, and establish a three-dimensional base database of the area:

[0044] Step 2, cultural heritage terrain modeling and cultural heritage scene modeling steps, obtain the texture and geometric shape data of each object in the cultural heritage area, and generate a three-dimensional model of the ground objects in the area;

[0045] Step 3, the cultural heritage 3D spherical system integration step, obtains the architectural process data of the cultural heritage area, and embeds the measured information of the area's topography and scenes into the 3D model of the a...

Abstract

The invention discloses a culture-heritage three-dimensional-scene generation method which includes the following steps: step1: a culture-heritage remote-sensing data preparation step: obtaining geographic information data in a culture-heritage region and establishing a three-dimensional base database of the region; step2: a culture-heritage landform modeling and culture-heritage scene modeling step: obtaining texture and geometrical shape data of different objects in the culture-heritage region so as to generate a ground-object three-dimensional model of the region; step3: a culture-heritage three-dimensional spherical-system integrating step: obtaining building process data of the culture-heritage area and insetting landform and scene real-time measurement information of the area into the ground-object three-dimensional model according to a building process sequence and environment background information. The culture-heritage three-dimensional-scene generation method is capable of improving the speed and precision of large-scale culture heritage modeling and providing an integrated dynamic index of a culture-heritage single-body model and an environment model so that the method has complete management and update capabilities.

Description

technical field [0001] The invention relates to the field of modeling and management of cultural heritage, in particular to a system and method for generating a three-dimensional scene of cultural heritage. Background technique [0002] The modeling and management of cultural heritage has been a long-studied issue, but most cultural heritage modeling stays at the fine modeling level of small scales such as a temple, a mountain, and a single cultural relic. The construction of three-dimensional scenes of large-scale cultural heritage Insufficient research on modeling and integrated management. However, large-scale cultural heritage such as the Grand Canal, the borders of the Roman Empire, and the Silk Road are famous for their large geographical scale, numerous cultural relics along the route, and uneven digitization. [0003] Existing methods cannot quickly establish a 3D model of large-scale cultural heritage, nor can they add and integrate new local cultural heritage mode...
