【摘要】 该文利用数字近景摄影测量的方法,对构成立体影像的近景目标序列影像进行数字摄影测量处理,以提取目标模型的三维空间坐标。给出了自由网模型的构建方法和大角度模型拼接的方法,解决了三维空间模型在没有控制点,仅有相对控制条件下,光束法自由网平差解算的空间基准问题。并给了三维网空间定位的实现过程和结论。更多还原

【Abstract】 This paper chooses close -range target stereo image data as main topic of3DCM,and carries through comprehensive and systemic study on photogrammetry of free network bundle adjustment from theory to practice.On the data processing of spatial model location,free network bundle adjustment are introduced to solve the base of spatial location.Photogrammetry and non-photogrammetry information are integrated to develop a union adjustment system with self-calibration parameter.Simultaneously solved problems of the big angle linked between different models of a building around taking photo,and free network adjustment with none-control point and only relation controls used.Process of realization and results are given.更多还原
