摘　　要：提出一种从井下二维摄影图像中提取深度信息的方法 ,用于对油井管壁的缺陷探测。首先讨论摄影测量学的公式和算法 ,导出适用于柱体测量的公式 ;然后采用两点定位的思想 ,确定摄影测量学中坐标系统的三个旋转角 ,计算旋转矩阵。The paper sets up a method which can be used to pick up particular information from the planar images taken in the oil well to detect the lacunas in the tube well. At first the formula of measuring the cylinder is deducted from the basic formulas and algorithms of photogrammetry. Then a way of computing rotation matrix of coordinate system is introduced in this paper, in which three rotation angles are decision through choose tow certain points from image of oil well. Finally, the result of the software emulation is given.
