The action principle of the frock is：In terms of the coordinate of the coordinate and the 3rd target 43 that measure the first target 41 by total powerstation comes
Exemplified by the coordinate for calculating hidden point to be measured, if the coordinate of target point 8 is（x,y,z）, it is assumed that total powerstation measures the coordinate of the first target 41
For（x1,y1,z1）, it is assumed that the coordinate that total powerstation measures the 3rd target 43 is（x3,y3,z3）, because the target center of the first target 41 arrives
The distance of the target center of 3rd target 43 is equal with the distance of target center to the target point 8 of the 3rd target 43, and the target center of the first target 41,
The target center and target point 8 of 3rd target 43 are on same straight line, so the target center of the 3rd target 43 is in the target of the first target 41
Between the heart and target point 8 on the midpoint of line, so:x=2x3-x1,y=2y3-y1,z=2z3-z1, so the coordinate of target point 8 is
（2x3-x1,2y3-y1,2z3-z1）.Because target point 8 and hidden point to be measured contact, the coordinate of target point 8 and hidden point to be measured
Coordinate is equal, so the coordinate of hidden point to be measured is（2x3-x1,2y3-y1,2z3-z1）.
