摘要
针对传统风貌街巷测绘方法和成果展示体系不足,研究采用三维激光扫描技术、无人机倾斜摄影技术等非接触式测绘技术获取传统风貌街巷高精度、高密度、全方位的测绘数据,在此基础上制作准确、完整的图形成果和精细的实景三维模型,形成一套完整的成果展示体系。基于木洞镇传统风貌街巷的实验结果表明,空地一体非接触式测绘技术方法既提高了测绘工作效率、又保证了测绘成果精度、还丰富了测绘成果形式,可以广泛应用于传统风貌街巷保护测绘工作中,为其留下宝贵的历史信息。
In view of the deficiency of mapping method and results display system in protection of traditional streets,the study applies non-contact surveying and mapping technologies such as 3D laser scanning technology,UAV aerial survey technology and tilt photography technology to obtain high-precision,high-density,omni-bearing surveying and mapping data of traditional streets.On this basis,accurate and complete graphics results and fine real-scene 3D models were produced to form a complete set of results display system.The result of this case study shows that the new method applied in surveying and mapping work improves efficiency,ensures accuracy,and enriches the form of results.It can be extensively used in traditional streets,surveying and mapping,leaving valuable historical information for traditional streets protection.
