[0027] Prism connecting rod is directly connected with a pair of measuring small prisms, and the connecting rod has sufficient strength and rigidity while maintaining lightness. The length and coaxiality of the connecting rod are accurately calibrated to improve the accuracy of calculating the coordinates of the target to be determined through the double prism coordinate extension line. A rotating fixed mechanism is designed on the lower measuring small prism, which includes a sleeve, the lower measuring small prism is bolted to the upper part of the sleeve, a fixed part is clamped in the sleeve, and the fixed part is arranged to be freely rotatable in the sleeve, so that the double prism centering rod can be rotated by 360° around the shaft to any desired angle. After rotating to the set angle, a common hexagonal fixing bolt is used to clamp the fixed part through the threaded connection mouth, and the rotation to the desired angle can be fixed and maintained.

By tightening the fixing bolt, the measurement can be started.

[0029] Positioning method: double-prism extension line is used to measure the calibration feature points: the direction of the double-prism is adjusted by using the sleeve type rotating fixing mechanism to align the direction of the total station, because the upper prism A, the lower prism B and the point C to be measured are on the same straight line in the space, the three-dimensional coordinates of the centers of the prisms A and B are measured by the total station, and the three-dimensional coordinates of the point C to be measured are accurately calculated according to the extension line method.
