为了解决大型装备中隐藏区域的空间坐标测量问题，提出一种基于光学标靶与测距仪的激光测头，该测头与全站仪或激光跟踪仪构成非接触测量系统。测量时，激光测距仪发出的激光对准被测点测得其距离，用全站仪或激光跟踪仪瞄准光学标靶，实时获取激光测头的空间坐标，同时激光测头测得其自身的空间姿态角，然后通过坐标变换得到被测点的空间坐标；并进行了实验验证。结果表明，该测量系统可以使得组合测量的量程扩大并保持较高的空间坐标测量精度。

In order to solve the coordinate measurement of hidden parts in large equipment , a laser probe based on optical target and rangefinder was proposed , which was combined with a total station instrument or a laser tracker to form a non-contact measurement system .During the measurement , the laser beam from the rangefinder was set to touch the measurement point and the distance between the rangefinder and the point was measured .And then, the optical target was aimed at by the total station instrument or the laser tracker .The spatial coordinates and the attitude angles of the laser probe were gotten.Finally, the spatial coordinates of the measured point was calculated by coordinate transformation .After theoretical analysis and experimental verification , the results show that the measurement system could expand the measurement range and achieve reliable and higher measurement precision .
