基于模糊综合评价的倾斜摄影三维建模质量评估方法研究

Research on evaluation method of oblique photography 3D modeling quality based on fuzzy comprehensive evaluation

由于地面工程建设地形起伏较大,采用传统的倾斜摄影技术得到的三维模型质量精度可能存在较大差异,因此需要设计一种客观而准确的模型质量评估方法。文章首先对无人机倾斜摄影的影像进行了三维建模,然后分析了三维模型的成果精度,最后构建了三维模型成果质量模糊综合评价体系,实现了对倾斜摄影三维建模质量成果的客观化评价。该方法为地面工程的数字化移交提供了准确的参考依据,对确保工程施工阶段和生产运营阶段的顺利进行起到了重要作用。

Due to the significant terrain fluctuations in ground engineering construction,there may be significant differences in the quality accuracy of 3D models obtained using traditional oblique photography techniques.Therefore,it is necessary to design an objective and accurate model quality assessment method.This article first conducted a 3D modeling of the images captured by drone oblique photography,then analyzed the accuracy of the 3D model results,and finally constructed a fuzzy comprehensive evaluation system for the quality of the 3D model results,achieving an objective evaluation of the quality of oblique photography 3D modeling results.This method provides accurate reference for the digital handover of ground engineering and plays an important role in ensuring the smooth progress of the construction and production operation stages of the project.
