三维激光在古建筑测绘中测点布置的模糊评价方法

Fuzzy Evaluation Method of Measuring Point Arrangement of 3D Laser in Surveying and Mapping Ancient Buildings

传统测绘技术难以实现古建筑测绘的三维可视化以及测量过程的无接触化和无损伤化,而三维激光扫描测绘技术在这方面具有特别优势。本文针对现有三维激光测绘方法在现场测绘中未能考虑如何合理确定测点布置的问题,将引入模糊数学方法和层次分析方法建立出测点布置的评价方法,以期对实际工程中的测点布置情况进行合理性评价,为测点的布置提供建议和意见,从而提高野外测绘的工作效率与成果质量。

It is difficult for traditional surveying and mapping technology to realize the three-dimensional visualization of surveying and mapping of ancient buildings and the non-contact and non-destructive testing of the surveying process. The 3 D laser scanning surveying and mapping technology has particular advantages in this respect. In this paper, the existing three-dimensional laser mapping method in the on-the-spot surveying and mapping can not consider how to rationally determine the layout of measuring points, the introduction of fuzzy mathematics and analytic hierarchy process to establish the method of measuring point layout, in order to measure the actual project The rationality of the layout of the situation assessment for the arrangement of measurement points to provide advice and opinions, thereby enhancing the efficiency of field mapping and the quality of results.
