Abstract
Abstract. Building the fine 3D model from outdoor to indoor is becoming a necessity for protecting the cultural tourism resources. However, the existing 3D modelling technologies mainly focus on outdoor areas. Actually, a 3D model should contain detailed descriptions of both its appearance and its internal structure, including architectural components. In this paper, a portable four-camera stereo photographic measurement system is developed, which can provide a professional solution for fast 3D data acquisition, processing, integration, reconstruction and visualization. Given a specific scene or object, it can directly collect physical geometric information such as positions, sizes and shapes of an object or a scene, as well as physical property information such as the materials and textures. On the basis of the information, 3D model can be automatically constructed. The system has been applied to the indooroutdoor seamless modelling of distinctive architecture existing in two typical cultural tourism zones, that is, Tibetan and Qiang ethnic minority villages in Sichuan Jiuzhaigou Scenic Area and Tujia ethnic minority villages in Hubei Shennongjia Nature Reserve, providing a new method and platform for protection of minority cultural characteristics, 3D reconstruction and cultural tourism.

The system is applied to the indoor-outdoor seamless modelling of distinctive architecture existing in two typical cultural tourism zones in China, that is, Tibetan and Qiang ethnic minority villages in Sichuan Jiuzhaigou Scenic Area and Tujia ethnic minority villages in Hubei Shennongjia Nature Reserve
4.2 Results and Discussions This study mainly focuses on the 3D reconstruction of the outdoor surface and indoor structure for two typical cultural tourism resources
Summary
With the rapid development of Chinese tourism, cultural tourism resources become a new direction. In the recent years, new residential construction in Jiuzhaigou are mainly made of brick or reinforced concrete structure, while traditional cedar chips roof is replaced by tile roof, and rammed earth walls were changed to brick This type of building has a richer exterior decoration and colour and integrates more Han Chinese architectural elements. The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XL-4/W5, 2015 Indoor-Outdoor Seamless Modelling, Mapping and Navigation, 21–22 May 2015, Tokyo, Japan measure the geometry and attribute information by the acquired images, and automatically model based on this information It solves the problems of indoor-outdoor data acquisition and integrated modelling, and provides a new method and platform for the protection of minority cultural characteristics, 3D reconstruction and cultural tourism
