| 设计了一种新型
带有自标定的数字准直瞄准测量系统。系统采用测微准直望远镜与CCD视觉系统相结合的方式，将测微准直望远镜的目视测量视场转换成数字测量视场，进而实现在整个数字视场范围内取样测量。通过对CCD相机的角度当量和位移当量进行标定，可直接计算出线位移和角位移，实现了数字化测量。通过实验验证，该系统的定位测量不确定度优于激光跟踪仪，定向测量不确定度优于经纬仪，可用于工业大尺寸测量。 |
| 英文摘要: |
| A novel digital
collimation telescope with self-calibration is presented. By combining micrometric collimation telescope with CCD camera which is used to collect the visual field of the micrometric collimation telescope instead of eyes, it realizes measurement in the whole digital visual field. Through the calibration of the CCD camera's angular equivalent and position equivalent, the positions and angles can be calculated directly. The experimental results show that the position uncertainty of the system is superior to a laser tracker; the angular uncertainty of the system is superior to a theodolite. Therefore, the digital collimation telescope can be used for industrial large-scale measurement. |
