As for the not intervisible cylinders, you can measure the angles of station point
with cylinder in Hz Left and Hz Right and the shortest distance of station point to
cylinder firstly. Then calculate the coordinate of cylinder center and radius of
cylinder through the geometric relationships. The shortest distance between station
point and cylinder is in the bisector of angle of station point with cylinder in Hz Left
and Hz Right. Turning the instrument to make the collimation axis in the bisector of
