无人机倾斜摄影测量在农房地调查中的应用

Application of UAV Tilt Photogrammetry in the Investigation of Rural Houses

以农村房地测图为研究对象,介绍了调查项目的基本情况,利用无人机倾斜摄影测量完成影像获取和处理,并进行精度检测工作。利用相关软件建立了三维模型,与测图成果进行比对,计算模型和测图成果的点位误差。根据计算结果可知,模型和测图成果的精度满足数据处理要求,可用于农村房地调查中的地籍图测绘,但也存在一定的局限性,有待改进。

Through taking the rural house mapping as the research object,the study introduces the basic situation of the investigation projects,utilizes UAV tilt photogrammetry to complete images acquisition and process,and does accurate measurement.Through utilizing related software,3D model is established,mapping achievements are compared,and the error in point measurement of the model and mapping achievements are calculated.According to the calculation results,the precision of model and mapping achievements can meet the requirements of data processing.It is can be used in cadastre mapping in the investigation of rural houses.But there are some limitations,and it needs improvement.
