摘要
针对倾斜摄影测量技术在测图精度验证方面研究较少的情况,本文利用前方交会原理对倾斜摄影测量测图精度进行验证。首先,采用消费型飞马D200无人机搭载D-OP400倾斜摄影像机获取多视影像数据;其次,用垂直数据构建垂直实景三维模型,采用多视倾斜数据构建倾斜实景三维模型;最后,通过在立体模型、垂直实景三维模型及倾斜实景三维模型上量测检测点坐标,验证成果精度。结果表明,利用前方交会法进行倾斜摄影测量测图精度优于垂直摄影和双片前方交会立体模型测图精度。
In view of the lack of research on mapping accuracy verification of oblique photogrammetry,a method of accuracy verification of oblique photogrammetry mapping based on forward intersection is proposed in this paper.Firstly,the consumer Feima D200 UAV carrying with D-OP400 tilt camera is exploited to obtain multi view image data.Secondly,vertical data is used to construct vertical real scene 3D model,and multi view oblique data is used to construct oblique real scene 3D model.Finally,the accuracy of the results is verified by measuring the coordinates of the detection points on the stereo model,vertical real 3D model and tilted real scene 3D model.The results show that the mapping accuracy of oblique photogrammetry based on forward intersection is better than that of vertical photography and two slice forward intersection model.
