Abstract

Historical villages bear historical, cultural, architectural, aesthetic, and landscape values, but they are facing a series of dangers and problems during the process of urbanization. Digital survey for traditional villages plays a crucial role in the preservation, planning, and development of this kind of heritage. The introduction of the terrestrial laser scanning technique is essential for heritage surveying, mapping, and modeling due to its advantages of noncontact measurement, accurate sensing of complex objects, and efficient operation. In recent years, TLS and related processing software (“SCENE”) have been widely presented as effective techniques for dealing with the management and protection of historical buildings in Fenghuang village. Thus, this paper highlights the process of using laser scanning to obtain architectural data, process point clouds, and compare the characteristics of historical buildings in Fenghuang village. The cloud-to-cloud registration technique is applied to build point clouds. As a result of model construction, some architectural patterns are summarized in this village, such as the spatial sequence of ancestral halls, the dominant position of memorial halls, and the character of building decorations and roof slopes. Furthermore, a BIM model is also explained to fulfill the statistical function for architectural components. In the future, more research can be fulfilled based on the built point cloud model, which will be beneficial for the development of the whole village.

Highlights

In the age of fast economic development and urbanization, traditional villages and rural lifestyles are confronted with a series of crises, especially in developing countries such as China
The survey method focuses on using territorial land scanning (TLS) to acquire comprehensive architectural data of the diverse elements of historical buildings in Fenghuang, including five steps: designing the scanning scheme, obtaining site data, processing point clouds, and comparing the historical buildings
The internal and external parts of the buildings are both recorded by TLS, and the roof parts are scanned

Summary

Introduction

In the age of fast economic development and urbanization, traditional villages and rural lifestyles are confronted with a series of crises, especially in developing countries such as China. The values of historical villages have been gradually reconsidered. In China, more than 4000 villages are acknowledged as national traditional villages due to their historical, cultural, architectural, aesthetic, and landscape values [1]. There is an increasing number of scholars involved in studies on the protection of traditional villages [2], rural landscape [3], tourism of historical villages [4], and revitalization of the rural economy [5]. The protection of rural architectural heritage remains a topical issue among architects, landscape architects, and urban planners. Rural areas are peculiar owing to their characteristics in architectural forms
