| 摘 要： | 针对近景摄影测量中影像与地面坐标系间存在大旋转角的问题,在分析现有绝对定向算法的基础上,提出了一种适合大旋转角影像的绝对定向方法,采用奇异矩阵分解获取较准确的角元素初值,并结合最小二乘平差进行粗差剔除和绝对定向精确参数解算。试验表明,本算法计算简单、收敛速度快,具有很好的实用价值。

| Abstract: | Absolute orientation is one of the fundamental issues in Photogrammetry and Remote Sensing. It is also an important topic in computer vision and three-dimensional reconstruction. To overcome the problem of large rotation angles between model coordinates of images and the corresponding world coordinates in close range applications, a new method of absolute orientation which is suitable for large oblique angle image is proposed. Singular value decomposition of rotation matrix is used to obtain accurate initia... |
