基于三维激光扫描与无人机倾斜摄影技术的古建筑重建

Modeling ancient architectures by traditional methods can hardly obtain high precision 3D spatial information and the texture information of the target object at the same time. This study proposes to combine the 3D laser scanning technology and tilt photography measurement technology to quickly restore the 3D information of ancient architectures. This method fuses multi-source data by feature matching and establishes the complete 3D model of the ancient architecture (inside and outside). The validation using the Li's family temple in a traditional Chinese village in Fujian province, China, shows that the relative mean error of the established 3D model is 5 mm. Furthermore, this method increases the modeling efficiency greatly. In addition, the constructed model is used for 3D printing and indoor and outdoor display in different scales, and the availability of model is further verified. This research will provide technical support for the restoration and protection of ancient architectures.
