摘要
采用无人机倾斜摄影测量技术,对某项目进行“多测合一”作业,获取研究区实景三维模型,采用EPS软件进行内业数据处理,生成研究区“多测合一”测绘成果,并对其进行精度评定。经验证,倾斜摄影测量成果坐标中误差为0.013 54 m,满足小于0.05 m的限差要求,界址边长中误差为0.050 3 m,满足小于0.1 m的限差要求。故表明,倾斜摄影测量精度满足相关技术标准,可以作为“多测合一”测绘中的一个辅助作业手段。
This article uses drone tilt photogrammetry technology to carry out "Integration of Multi-measurements" operation on a project. It obtains the real three-dimensional model of the study area, uses EPS software for internal data processing, generates the "Integration of Multi-measurements" surveying results of the study area, and evaluates the accuracy. Based on verification, the RMES of tilt photogrammetric results is 0.013 54 m, which meets the tolerance requirement of less than 0.05 m, and the RMES of the boundary length is 0.050 3 m, which meets the tolerance requirement of less than 0.1 m. Therefore, it shows that the accuracy of oblique photogrammetry meets the relevant technical standards and can be used as an auxiliary operation method in "Integration of Multi-measurements".
