基于点云数据的传统村落 VR 展示研究 # ——以井陉于家石头村为例

VR Display of Traditional Villages Based on Point Cloud Data:A Case Study of Yujia Stone Village

摘要:

随着传统村落数字化保护进程的日益开展，利用虚拟现实技术（VR）对传统村落进行展示宣传契合现实需求。本文针对目前传统村落 VR 展示存在的场景建模效率低、真实感缺失等问题，提出结合地面三维扫描与低空倾斜摄影技术融合建模、高效建立村落实景模型，以增强虚拟现实场景的真实性。以于家石头村为例，阐述点云数据的采集路线，着重探讨模型的融合方法，然后将融合后的模型进行虚拟现实展示，最后对展示效果进行评价，并提出修正建议，以期为传统村落 VR 展示的场景建立提供借鉴与参考。

Abstract:

With the development of digital protection of traditional villages, the use of virtual reality technology (VR) to display and publicize traditional villages meets the practical needs.Aiming at the low efficiency of scene modeling and lack of realism in the current traditional village VR display, this paper proposes to combine 3D scanning and photogrammetric surveys to integrate modeling, and to efficiently establish a village scene model to enhance the authenticity of the virtual reality scene. The Case Study of the Yujia Stone Village, it elaborates the collection route of point cloud data, focuses on the model fusion method, then displays the model in virtual reality, and finally evaluates the display effect and proposes correction suggestions.
