Dam body vertical line displacement calculation method and device and photoelectric vertical line coordinatograph

The invention discloses a dam body vertical line displacement calculation method and device and a photoelectric vertical line coordinatograph, a direction observation sensor is embedded into a vertical line CCD, real-time synchronous observation is carried out on the direction observation sensor and vertical line radial tangential displacement data, and the data of a vertical line are corrected to a designed azimuth by calculating an azimuth angle, so that the vertical line displacement is calculated. Therefore, it is ensured that the radial tangential displacement data direction of the vertical line is consistent with the design direction, and the operation state of the hydraulic structure or the slope structure can be evaluated more accurately. 本发明公开了一种坝体垂线位移计算方法、设备及光电式垂线坐标仪，将方向观测传感器嵌入到垂线CCD中，并与垂线径切向位移数据进行实时同步观测，通过计算方位角，将垂线的数据修正到设计的方位上，从而保证垂线的径切向位移数据方向与设计方向一致，能够更加准确的评价水工建筑物或边坡结构运行性态。
